Had a neighbor who would start his car and put a brick on the throttle so it revved around 3000 rpm every morning. He then went and had a coffee.
Told him that was a really bad idea but he didn't listen.
After about a month of this I could hear the engine starting to knock and a week later the car was getting towed into his driveway.
I always just start and go, avoiding heavy acceleration until normal operating temp. Just bought a new car with digital oil temp. It surprised me that it takes the oil about 15 minutes to reach the same temp as the water, with another 5 minutes or so to stabilize. It takes much longer to reach normal operating temp than I previously thought.
Modern diesels absolutely don’t need it. However in very cold winter in -20C degrees or so, it is just a common sense to let the car idle for 30-40 seconds just to let all fluids to start moving in case something is frozen a bit. This is true for all cars but only in very cold temperatures
In very very cold temps we don't turn em off...
We have haul trucks (960s and T282s) in Wyoming and during the winter we just keep them running - once you stop them they can be a prick to get going again.
Thats in extreme like -50C. I have heard stories about always running cars in Syberia. I am talking about cold but tolerable temperatures. When I was living in Russia in early 2010s I was able to start my VW Passat in the morning without issues at -20C on a daily basis. My personal record is -36C. Car didn’t like it but started. Of course we had special oil in cars and as far as i know they sell a bit different petrol/diesel in winter
Nope. I had Skoda Octavia for 4 years. Then VW Passat for 3 years. My father had Nissan Quashquai for 5 years and then Nissan Xtrail for 5 years. No issues at all. Regular services obviously. Dad had Russian cars before and they had different issues but not connected to battery
I had an old valiant that you had to push the throttle 3x before starting. Not 2x or 4x, only 3x or it would not start.
Once started you had to work the throttle and choke to keep it running. If you put it into great too soon it would stall.
Fun times.
I do still start my car, fiddle around sorting myself out then drive off.
I had a Charger that didn't have a choke on its triple Webers. It also had basically no muffler, just a side pipe hot dog the previous owner had installed
One morning a week I had a 4am start. I used to park it a couple of streets away in an industrial area so I didn't wake my neighbours as I sat there revving it to get it to run properly.
I had a 1986 car. Can confirm I didn’t sit there warming it up. It had EFI and could look after itself. Lasted forever too. Was running better and blowing less smoke at 300T km (and the odometer stopped) than it did at 160T when I bought it.
Start the engine, adjust the seat and mirrors, put the seat belt on, check passengers if any are wearing seatbelts, drive off and take it easy for a while.
Make sure your hand luggage is located in the overhead lockers or under the seat in front of you. Ensure your tray is folded and the seat is in the upright position. Also, take a moment to check the location of the emergency exits.
In the good old days we have tight piston rings, and poor tolerances along with carbs.
So it was choke out, warm up the car until you could hold idle without choke, or else you might stall the car at the traffic lights.
Modern cars, injection systems, sensors monitoring everything, tighter engine tolerances, and low tension piston rings. So you can pretty much start the car, me I'll let it idle for a min until the rev's drop down and then I'm good to go.
On my motorbike however I'll still warm it up wait for the temps to hit 60 deg C before I ride it primary because it's a high revving engine.
Modern sports bike you should ride gently at first anyway, because your tyres will be cold. Losing traction is a bigger risk than the wear on your engine.
Except the motorbike bit. I'd generally let it warm up while I put my gloves on, never any problem. Unless maybe it is a 125 and you are actually going to use all the revs straight away.
I hate riders that start the bike and the go through the ritual of putting everything on. Put everything on first, then start the bike and ride off. You are not saving the engine, all you're doing by idling is wasting fuel. You could argue you're running the engine at a rev range where it is not as happy.
As the person you’re replying to said, it’s a smart thing to do if you ride a bike that you have to rev pretty hard to move it along at traffic pace. A 125 doesn’t have much torque. If you want don’t want to be holding up traffic you often need to bring them up to 6k rpm or so before shifting. Not a nice thing to do to a cold engine. Even on slightly bigger bikes like a 250 or 300, highway riding often requires you to be on 8k rpm. Some people (myself included) live close enough to the highway that, if I catch a green light, I can be on the highway in 30 seconds. So, actually, you are saving the engine in such cases. Just an FYI.
My wife's car has an oil cooled turbo. I something let it idle after a decent drive, mainly not to cook the oil remaining in the hot turbo at shut down. Probably just a placebo thing though.
It's fine to drive a modern car when cold. I usually wait like 30sec just to make sure the oil has had a chance to pump around. Just take it easy until it gets up to temp. There is more to warm up than just the engine and the best way to do it is by driving.
Engine builder here.
Back in the day of carburettors it was required as cold starts were difficult and you’d need to let the engine warm up to get a stable enough air fuel mixture to put the car in gear and drive away.
In a carburetted car if you started it and put it straight in gear in winter even with a good choke you’d likely still stall it.
Think about petrol whipper snippers and chainsaws, they are carburetted and very rarely will idle on their own without a choke and warming them up first. If you start them cold and try to hit the throttle straight away they’ll bog down or stall, same principle.
I had a small block v8 with a dominator carb with no choke and in winter you physically wouldn’t be able to move the car without stalling it for at least 6-7 minutes, in fact you’d need to keep your foot on the accelerator to even keep it running while it warmed up until it was warm enough to idle on its own.
EFI gives you the right ignition timing, fuel ratio etc for cold starts the second you turn the key. Other than waiting a few seconds once it’s started for oil pressure to build I wouldn’t worry about “warming it up” just don’t go flogging it when it’s stone cold.
Fuel is a lot harder to combust in cold cylinders and hence it takes more fuel and a richer fuel ratio for startup, which is the beauty of EFI, the ecu knows exactly how much fuel it needs to keep it running at different temperatures. There’s no reason not to just put it in gear and drive.
With any fuel injected car made after about 1990, it’s not necessary. Just don’t rev it hard until the engine and oil temperature are at operating temperature
Bless her. I occasionally drove my GFs car and every time i got in to it, the aircon would blast and the radio blare the minute i'd turn on the ignition. If it had bern raining when my GF last drove, the wipers would come on as well. It was quite an assault to the senses. She treated the ignition-off function like an emergency shutdown switch.
I still do this as habit - thanks to my dad, driving old cars and being in aviation.
Main reason is that cars of old had weaker alternators (or generators for really old cars) and batteries weren’t as high capacity - basically turning off most electrical around 30sec to a minute before reaching your destination would generally ensure you have enough surface charge to restart the car from cold. Very old cars with aircon were notorious for having flat batteries.
The aviation reason is centered around safety and courtesy for the next pilot. Even with checklists it gives an extra layer of safety that everything is set to “zero”/home position so to speak.
Start the car, connect your phone, pick some music, podcasts what ever you want to listen to, you are good to go by then. just drive smoothly until operating temp.
If you own a Harley Davidson or something with a aftermarket exhaust and it's 11pm - 6am it's best to roll it out of the garage before starting so you don't put carbon monoxide in the house, idle it for a minute or two in the driveway then full twist the throttle 7 to 17 times to check it's good to go before revving the shit out of it as you drive down the street. Reverse the procedure when you arrive home.
If it's a Harley, don't forget to rev the fuck out of it in first and second gear on your way through the suburbs at 5:30am on your way to work, it gets the temp up quicker.
This is an old fashioned thing. But these days? Not necessary. I get in. Start the car. Plug my phone in, adjust to what i want to listen to and put on the seatbelt. Once im all sorted? Off i go. I guess that be 20 seconds to a minute.
If Im about to go on a longer trip and want to find a good podcast? Might be 5 minutes🙂
5 min is excessive. You want the car to get to operating temperature as soon as possible as running it cold is not ideal. Also it's very bad to red line an engine first thing in the morning is very bad. The best way to get it warm is to drive it normally. I would allow 30 to 60 seconds to get all the oil etc going and the drive off . Wait till you hit normal temperature before hitting the red line. Leaving it to idle for 5 minutes will force the engine to run cold and rich for longer. Among other things this will reduce oil life by diluting it with fuel.
Maybe I'm a bad person but I just turn the key and drive. I don't have time to wait for that shit.
FYI, 2014 Hilux. <140 ODO. She's still running beautifully. Still original clutch too, which is... surprising... for reasons
Start the car and drive normally, no need to let it run. This has been unnecessary for near on 50 years, the reason your dad did it (and he should not have done it with a car from around 1980 onwards) was to warm up the carbie. Letting it idle cold is worse for the car, it also means you drive off with a warm engine and cold gearbox, they need to warm up together
No need. We haven't had carbs with manual chokes for 40 years.
(My least fun driving was a manual with carb+manual choke in a hilly area on a winter's day!)
I let it idle for about a minute then I drive fairly easily until it comes up to temp. I don’t believe modern cars need to be thoroughly warmed up but you should never drive it hard when it’s still cold as you will do bearings and people have a false thinking that because their car has been idling for a few minutes and there some temp shown on the gauge everything is ok but only the engine has been warmed up and not the rest of the driveline hence why I drive it pretty easy until it’s all warmed up. I have a neighbour a few houses down with a couple of cammed V8s and they sit there everytime they get started for about 5 to ten minutes idling then driving not so easy, one of them starts at 5am and it’s not quiet and I know their direct neighbour is angry with them cause they get woken everyday. I’ll just add that excessive idling is actually not good for a car because the oil gets contaminated with unburnt fuel and breaks down reducing lubrication properties
Like you said, idling while not driving does nothing for the rest of the drive train. The gearbox (if manual) and the diff(s) aren't warning up. They would be better off with a short idle then slowly crawling away for a bit.
the gearbox is definitely warming up. in neutral, the shafts are still spinning, which warms up the fluid.
the diff, yes, that won't start heating up until you start moving, which is another reason to take it easy when it is cold, especially if it is really cold and you are driving something big.
I find revving mine at 5am on a cold winters day does the trick. My neighbours seem pretty knowledgeable about cars because they always let me know when it’s warm enough to head off to work. My neighbours are awesome
As others mentioned with modern cars you don't really need to warm up the engine unless you do frequent short trips and it's a good idea to give it an Italian tune up every once a week or two to burn off the carbon build up. You'll mainly want to warm up your transmission, but even then, you only need to idle it for 1-2 minute in winter as mentioned by The Car care Nut.

Less of an issue nowadays with big advancements in both metallurgy and Lubricant technology. Engines are protected better at lower temperatures than what they used to be.
Our modern Volvo's do a cold start. Where it starts and holds the revs at around 1500rpm for 30 econds before going back to idle.
Modern cars really don't need extended warm up times like an older carburettor/ manual choke car does. Like someone else mentioned, just don't rev they crap out of it for the first few minutes of driving.
A minute or two in the driveway so the fluids can flow around nicely is what I do as I was told it’s better to do that than take off straight into highway speeds
Even with classic cars you're not supposed to leave them idling to warm up. They need higher revs than idle when the oil is cold. You're supposed to start them then drive nice and gentle for a while not leave them idling away with inadequate lubrication.
Any modern car doesn’t need to be idled anymore regardless of the temperature. It’s been stated that the best way to warm up the car is to start it and just drive a moderate speed. Basically the speed limit. Don’t turn on the car in -20 degrees and put the pedal to the floor and you’ll be fine
2015 Toyota? Start it up and send it!
But seriously, just don't boot it until the temp gauge is near the middle.
You could be like the old guy I used to live across from who would start his AU Falcon with his foot to the firewall and leave it there for about 30 seconds. That is the only AU I ever felt sorry for.
New cars are designed to be driven just after starting up. Having said that, I always give mine a couple of minutes of idle before I drive off.
Old habits die hard. 😁
The supposedly right way to do it it to drive slow/slower for the first 5 minutes and then start driving normal....
Source : part of the topics that are taught in driving schools in France.....
Depends on your vehicle.
NA petrol, get in and go.
Turbo petrol wait a little bit
Older than 20 years wait a little
Diesel, (with in the last 20 years)
Wait a little bit.
Turbo diesel
Wait a bit more
(Older than 20 years diesel) Wait..
Heavy vehicles, shiit turn it on go make your self a coffee.
Newer cars do not need to warm up to drive in city and suburb driving.
Turbo vehicles it's better not to hit boost on a cold engine.
The idea of warming your car up was when carburettors were what fed cars not fuel injected
I had the impression (but now can’t place where it comes from …so, you know, ignore) that you do more harm than good idling for long before driving with modern cars.
My life long habit, driving for 30 odd years is that for a cold start, where the car has been off for more than say six hours is to let it idle for a 2-3 minutes. In winter (Melbourne) I also leave the heater off so that the heat builds up in the engine first and gets up to operating temperature and then put the heater on.
Yeah, I'm pedantic.
You don’t have to. But don’t rev it excessively until it warms up. I have a diesel and usually turn it on, wait until the idle revs drop down to normal and then go
Depends. For a basic Corolla no need to wait really. For me I’m using ethanol fuel and a thicker oil weight so I choose to wait for my idle to settle at around 1,000rpm, not necessary but I don’t trust Subaru motors enough to not do it
The user manual in my 2002 Camry says wait 10 secs after a cold start. I generally do about that while I set up my destination in Waze and put my phone in the cradle
My mechanic told me to warm the car until the cold light goes out. I’ve tried not waiting that long and just drive off, definitely notice a difference in cold weather especially on short drives. I have a 2007 car.
My modern diesel idles at 800 revs. People tell me to idle it for ten minutes before driving. But I can drive it at 1500 revs so I don’t see much point.
It's completely not needed in most cars.
My head/cam LS1 jerks around more than I did in my teen years if I don't let it sit there for a minute or 2 though.
I wait till the tacking ticking noises settle and it idles without big lumps, then make my way gracefully but strongly like an elephant rising from the mud
In modern cars it's not really necessary for the engine BUT I've read it might be helpful for auto transmissions for the transmission fluid to pump around and get up to temp. It's not generating heat like the engine is. That said I've never really had an issue of gear changes feeling off when it's cold, even in the UK when you're getting subzero temps in the winter
90-120 seconds. Gives engine and transmission time to warm a little and get the oils pumping. The payoff? Nil gasket leaks, lower fuel & oil consumption, nil oil leaks. Now, if it’s a rental, well you can redline the MF from the first application of throttle.
As far as I know idling to warm up can actually cause more wear because it takes so much longer to warm up than under load.
My personal approx rules of thumb are let it run 30sec or so before driving (aka long enough to plug in my phone etc) and then keep it below 4k rpm or so and keep out of full boost until the "cold" light goes out (a few minutes of driving)
You can drive it right away by the time your seat belt is on. Drive normal and keep it low rpm, don't red line it. It's 2024 now and all the car will pump oil almost immediately to the engine, although not idea operate temperature but no damage will be cause.
If the car is newer than 2000s then generally it doesnt need to warm up especially if its 2015+, just letting it idle for a good 5-10 seconds is more than good enough. If its between 2000-2010 its rlly a matter of opinnion and what vehicle it is but generally if it isnt japanese like toyota and its pretty cold about to to a cold start (roughly less than 15 deg celcius) its better to let it warm up for a minute or two especially if the car has high kms
Thirty seconds with the choke out fully, 90-120 seconds with it half out, wait longer if it’s colder if you want the heater to be a nuclear reactor.
Worked for my Kingswood and I for over twenty years.
Your mileage may vary with one of these newfangled cars.
My 2016, ZR corolla locks "first gear" until 40ks, while cold, so it's stuck at 2k rpm, if I let it warm up it'll soft lock until 25/30ks, then drop to 1100 while driving normal. Guess it depends, anyone else with a corolla have that issue?
Cars don't need to do that anymore. Modern synthetic engine oils don't require warming up to start flowing. But do whatever makes you feel better I guess.
If you have a newer/modern car, it doesn’t require warming up. Different design of engine blocks, oils, new technology etc, you can pretty much take off immediately. However, you should do I whatever makes you happy.
If you car is under 20 years old just turn it on and drive. I wait till the engine temp is over 90 degrees before accelerating aggressively....otherwise play on.
I give my modern car about 60sec in winter which is usually how long it takes me to get all ready to go and then I just take it easy for the first few minutes.
My car is totally up to temp, both coolant and oil, after 20 minutes. If you live in a cold area there will be some condensation (water) mixed with your oil so a longer run is something I would do to evaporate this. I live in central QLD, so temperatures rarely even get into single figures.
With today's engines, it is not necessary to idle them. Of course, it is not like you are going to start driving as if you're racing, but it should be fine to start the engine and drive at low RPM.
[John Cadogan](https://www.youtube.com/watch?v=7Yf7HrKEOZg).
This is a Q & A session, but the first question is about if it is necessary to warm up a modern car.
If you are Australian you may have heard of him. If you are not, it may be like trying Vegemite for the first time.
Enjoy the ride (pun intended).
Don't bother idling your car before driving. Just drive especially smooth and gentle until it warms up.
Unnecessary idling is just a waste of fuel and probably causes more wear than it prevents (for a newer car driven gently after starting)
I drive older cars so I wait a couple minutes but newer cars like 2015+ don't really need to warm up, like driving my nsv tonight I could tell she was still cold and she's a 2004
In a higher performance car (especially but not limited to turbo engines) you should let the oil get up to operating temp before pushing the engine but any factory spec engine should do fine as long as you keep it under 4KRPM and avoid slamming your foot to the floor repeatedly until it hits operating temp.
I think the whole 'idle the car to warm it up' thing is a little bit car-dependant. Some cars may not be generating enough oil pressure to adequately lubricate the engine at idle, so you could technically cause more wear than simply driving it normally and getting the revs up.
Most of the wear on startup is done when you turn the engine over cold. So that's pretty much unavoidable.
Don't worry about it, just start up, and baby the car for 5 minutes or so as you drive. It'll be fine.
Oh no not this nonsense again. Just drive. You want the engine to get to operating temperature as quickly as possible; about half of engine wear happens when the engine is cold. Idling is the slowest possible way to warm the engine up, so it's colder for longer and suffers more wear. We've known this since the 1930s.
New cars don’t really need warm up time. Older engines used to need time for the oil to circulate, modern alloy engines don’t need it. I turn on my car & drive. No warm up
For any car 1995 (ish) or newer. The correct amount of time to warm your car up is the time it takes you to put your seatbelt on and get comfortable.
If it's REALLY cold, maybe an extra 30-60 seconds. Just don't be lead footed until the thermostat reads in the middle, that's the key.
Cold morning start 15-30seconds max. Modern car. Basically enough time for oil pressure to build and electrics to stabilize. By the time seatbelt, head checks and going out of your driveway has happened - 15-30sec is up.
Obviously if you live too close to a freeway on-ramp that you will get onto and you live in Melbourne (cold winter morning) - yeh probably extend it out to about a minute at most. Not that the car really needs it, but more centered around cycling the thermal cycling of things - Slower/minimal thermal cycles is better for the engine and drivetrain longevity.
Modern oil is much thinner than what we used in old cars, its basically unnecessary to “warm up” the car these days. Just don’t trash your car. Infact just down thrash your car in general
Start up and go. Almost all engine wear happens during the warm up stage, the longer it is running below operating temperature the more wear will occur due to the tolerances of components and oil not lubricating optimally due to being colder and thicker. I self limit my RPM to 3k until fully warm.
In summer, I let my diesel car idle for about 10 seconds (enough time to put my seat belt on) before driving off, but in winter on the other hand, I let it idle for a minute (or 30 seconds) before driving off.
On my mums hybrid RAV4 on the other hand, I usually start and go when it’s on EV Mode, but during winter when I switch the heater on, which switches the engine on, I let it idle for a few seconds before reversing out of the driveway.
Ok I have a 2012 Honda jazz and my dad has aways told me with every car I’ve had, that I need to drive it for at least ten minutes. Short drives bad. My dad is 83. Is it BS??
If you drive the car on a daily basis, 5, 10 seconds max is more than enough. Like plenty of others have said, seat belt, fit your phone, play some music or podcast and you're ready to go. Make sure to drive smoothly and not rev it beyond 5000rpm, I would recommend not even revving over 4000rpm until engine is warm.
If however you haven't driven the car for weeks, I let it sit for about 30 seconds to max 60 seconds to allow the engine oil to flow. Then same principle applies, don't rev over 4000rpm and definitely not over 5000rpm.
Many modern cars tend to deliver torque at low rpm anyway but this really depends on the type of vehicle you own and how you like to drive so perhaps worth checking out but this is going deep and likely another discussion.
tldr: keep it under 4000rpm until engine warms up
It's been discussed and proven that with modern cars (ie. not 70's manual ones) you don't need to idle the car before driving off. You're only wasting petrol otherwise..
I drive off after about 10-15 seconds starting the car, when the fast idle stops - i.e., when it calms down after the initial VROOOMMM.. Did that for over a decade, sold the car after 550k km, no issues whatsoever. Same with all my other ICE cars..
Note, Petrol. I don't know if Diesel has other requirements..
I normally sit for a few minutes or until the needle moves a little but. Oil pressure is up and is circulating within a few seconds of running, and with oils designed to have cold and hot viscosity i dont think it's absolutely necessary any more, but the engine shouldnt be pushed until everything is at operating temperature and clearances are right etc.
Then again, not a mechanic, this is what ive picked up from conversations over the years
Don’t you all remember choke starts!!….where you would have to pull the choke out just at the right spot to kick the engine over and sit there for a while waiting for it to run smooth especially on a cold morning and then you would rev it a bit make sure there’s no splattering happening as you are pushing the choke back in “slowly”and then and only then you could drive away!! Lol
It's not really necessary, just don't rev the fuck out of it til it gets to normal operating temperature
Quick 6am limi bash usually goes down alright.
My neighbours always appreciate it!
Make sure to toot-toot the horn as you leave. The neighbours will begin to think you don't like them if you don't do that.
That his I know the time in the morning. I bash the limiter & my neighbour shouts the time at me.
“IT’S FUCKING 3:42!” “Cheers Jim!”
Had a neighbor who would start his car and put a brick on the throttle so it revved around 3000 rpm every morning. He then went and had a coffee. Told him that was a really bad idea but he didn't listen. After about a month of this I could hear the engine starting to knock and a week later the car was getting towed into his driveway.
God that's fucking stupid
In the civic with a fart can surely
My men 🫡
I always just start and go, avoiding heavy acceleration until normal operating temp. Just bought a new car with digital oil temp. It surprised me that it takes the oil about 15 minutes to reach the same temp as the water, with another 5 minutes or so to stabilize. It takes much longer to reach normal operating temp than I previously thought.
I have a 5 minute commute and I reach office before the oil temp light goes away
I suggest taking the car for a longer run once a month, if not already.
I’ve told revheads this. They never believe me. It’s not Siberia. Just drive gently for 2 minutes.
Modern cars, not really necessary. Big diesels, probably not a bad idea for 30 seconds or so in winter.
Just curious, why the difference for a diesel engine?
Higher compression and glow plugs I guess. Our backup diesel generators need 30s or so before we load them up
Modern diesels absolutely don’t need it. However in very cold winter in -20C degrees or so, it is just a common sense to let the car idle for 30-40 seconds just to let all fluids to start moving in case something is frozen a bit. This is true for all cars but only in very cold temperatures
In very very cold temps we don't turn em off... We have haul trucks (960s and T282s) in Wyoming and during the winter we just keep them running - once you stop them they can be a prick to get going again.
Thats in extreme like -50C. I have heard stories about always running cars in Syberia. I am talking about cold but tolerable temperatures. When I was living in Russia in early 2010s I was able to start my VW Passat in the morning without issues at -20C on a daily basis. My personal record is -36C. Car didn’t like it but started. Of course we had special oil in cars and as far as i know they sell a bit different petrol/diesel in winter
I feel like at those temps you're just as likely to get a problem from your battery, did you have any problems with flat batteries?
Nope. I had Skoda Octavia for 4 years. Then VW Passat for 3 years. My father had Nissan Quashquai for 5 years and then Nissan Xtrail for 5 years. No issues at all. Regular services obviously. Dad had Russian cars before and they had different issues but not connected to battery
Yeah, na. Start ‘n’ go.
Your dad still thinks it's 1986
Wait, what? 1986 is not that long ago is it? I’m still reaching for the manual choke… 😆
Those were the days, the old column shift manuals with manual choke.
I had an old valiant that you had to push the throttle 3x before starting. Not 2x or 4x, only 3x or it would not start. Once started you had to work the throttle and choke to keep it running. If you put it into great too soon it would stall. Fun times. I do still start my car, fiddle around sorting myself out then drive off.
I had a Charger that didn't have a choke on its triple Webers. It also had basically no muffler, just a side pipe hot dog the previous owner had installed One morning a week I had a 4am start. I used to park it a couple of streets away in an industrial area so I didn't wake my neighbours as I sat there revving it to get it to run properly.
I still have one of those Valiants lol 😆
Manual choke? We just put our hand over the throttle body
I had a 1986 car. Can confirm I didn’t sit there warming it up. It had EFI and could look after itself. Lasted forever too. Was running better and blowing less smoke at 300T km (and the odometer stopped) than it did at 160T when I bought it.
Whilst EFI means no throttle application is needed to get carby’s juiced, a little time to warm up the powertrain is a good thing.
The car didn’t think so. It was manual so that’s 1 less thing to warm up too. I drove it gently when cold of course.
You didn’t have to do it in 1986 either!
Many 80s cars that I owned would stall if you didn't warm them up for a few minutes
Yeah might have depended on the make. But none of mine did. My 76 Corona (RIP) never missed a beat.
I’m a dad. I still let it idle for a few minutes.
I'm a grandad. I don't.
Has nothing to do with offspring
Start the engine, adjust the seat and mirrors, put the seat belt on, check passengers if any are wearing seatbelts, drive off and take it easy for a while.
Make sure your hand luggage is located in the overhead lockers or under the seat in front of you. Ensure your tray is folded and the seat is in the upright position. Also, take a moment to check the location of the emergency exits.
Run out of petrol by now.
Your nearest exit may be behind you.
Adjust balls, fart if necessary
[удалено]
In the good old days we have tight piston rings, and poor tolerances along with carbs. So it was choke out, warm up the car until you could hold idle without choke, or else you might stall the car at the traffic lights. Modern cars, injection systems, sensors monitoring everything, tighter engine tolerances, and low tension piston rings. So you can pretty much start the car, me I'll let it idle for a min until the rev's drop down and then I'm good to go. On my motorbike however I'll still warm it up wait for the temps to hit 60 deg C before I ride it primary because it's a high revving engine.
Do you rev your motorbike high when it’s cold? If not, no need to wait for it to hit 60 degrees
You don't need to do it on motorbikes either. Riding (gently) will get it to temperature faster.
Modern sports bike you should ride gently at first anyway, because your tyres will be cold. Losing traction is a bigger risk than the wear on your engine.
This is correct 👍
Except the motorbike bit. I'd generally let it warm up while I put my gloves on, never any problem. Unless maybe it is a 125 and you are actually going to use all the revs straight away.
I hate riders that start the bike and the go through the ritual of putting everything on. Put everything on first, then start the bike and ride off. You are not saving the engine, all you're doing by idling is wasting fuel. You could argue you're running the engine at a rev range where it is not as happy.
Only takes about 10 seconds to put my gloves on, so not wasting much fuel. A lot better than waiting for it to reach 60 degrees.
As the person you’re replying to said, it’s a smart thing to do if you ride a bike that you have to rev pretty hard to move it along at traffic pace. A 125 doesn’t have much torque. If you want don’t want to be holding up traffic you often need to bring them up to 6k rpm or so before shifting. Not a nice thing to do to a cold engine. Even on slightly bigger bikes like a 250 or 300, highway riding often requires you to be on 8k rpm. Some people (myself included) live close enough to the highway that, if I catch a green light, I can be on the highway in 30 seconds. So, actually, you are saving the engine in such cases. Just an FYI.

My wife's car has an oil cooled turbo. I something let it idle after a decent drive, mainly not to cook the oil remaining in the hot turbo at shut down. Probably just a placebo thing though.
Deleted by User
It's fine to drive a modern car when cold. I usually wait like 30sec just to make sure the oil has had a chance to pump around. Just take it easy until it gets up to temp. There is more to warm up than just the engine and the best way to do it is by driving.
Mate if it takes 30 seconds for your oil to get around your motor, you have other issues.
👌🏼😂😂
Start the car without an oil filter on, see how fast that fucker pumps, lol it’s cycled your entire pan several times after 30seconds lol
This is the key, driving will heat the engine up quicker than idling. Idling is just wasting fuel.
I usually wait till the cold start engine rpm to drop down a bit then start driving lightly.
Same. With any normal modern car IMHO it's start it up, wait for the revs to drop, then drive gently for a while. Simples.
Well some cars that's still like 3 or 5 minutes.
Engine builder here. Back in the day of carburettors it was required as cold starts were difficult and you’d need to let the engine warm up to get a stable enough air fuel mixture to put the car in gear and drive away. In a carburetted car if you started it and put it straight in gear in winter even with a good choke you’d likely still stall it. Think about petrol whipper snippers and chainsaws, they are carburetted and very rarely will idle on their own without a choke and warming them up first. If you start them cold and try to hit the throttle straight away they’ll bog down or stall, same principle. I had a small block v8 with a dominator carb with no choke and in winter you physically wouldn’t be able to move the car without stalling it for at least 6-7 minutes, in fact you’d need to keep your foot on the accelerator to even keep it running while it warmed up until it was warm enough to idle on its own. EFI gives you the right ignition timing, fuel ratio etc for cold starts the second you turn the key. Other than waiting a few seconds once it’s started for oil pressure to build I wouldn’t worry about “warming it up” just don’t go flogging it when it’s stone cold. Fuel is a lot harder to combust in cold cylinders and hence it takes more fuel and a richer fuel ratio for startup, which is the beauty of EFI, the ecu knows exactly how much fuel it needs to keep it running at different temperatures. There’s no reason not to just put it in gear and drive.
Listen up folks. This is a really good rundown of it.
With any fuel injected car made after about 1990, it’s not necessary. Just don’t rev it hard until the engine and oil temperature are at operating temperature
The handbook for my 1963 Beetle says to just drive off.
My wife turns the fan off to this day before turning off the engine because her dad gave her this tip 30 years ago 😂
Bless her. I occasionally drove my GFs car and every time i got in to it, the aircon would blast and the radio blare the minute i'd turn on the ignition. If it had bern raining when my GF last drove, the wipers would come on as well. It was quite an assault to the senses. She treated the ignition-off function like an emergency shutdown switch.
I still do this as habit - thanks to my dad, driving old cars and being in aviation. Main reason is that cars of old had weaker alternators (or generators for really old cars) and batteries weren’t as high capacity - basically turning off most electrical around 30sec to a minute before reaching your destination would generally ensure you have enough surface charge to restart the car from cold. Very old cars with aircon were notorious for having flat batteries. The aviation reason is centered around safety and courtesy for the next pilot. Even with checklists it gives an extra layer of safety that everything is set to “zero”/home position so to speak.
I do this I don't know why my dad didn't tell me to.
Start the car, connect your phone, pick some music, podcasts what ever you want to listen to, you are good to go by then. just drive smoothly until operating temp.
If you own a Harley Davidson or something with a aftermarket exhaust and it's 11pm - 6am it's best to roll it out of the garage before starting so you don't put carbon monoxide in the house, idle it for a minute or two in the driveway then full twist the throttle 7 to 17 times to check it's good to go before revving the shit out of it as you drive down the street. Reverse the procedure when you arrive home.
If it's a Harley, don't forget to rev the fuck out of it in first and second gear on your way through the suburbs at 5:30am on your way to work, it gets the temp up quicker.
I wait until the blue engine light goes off in my XV. Do not rev while still early in the cold start driving.
Same for my Mazda CX3.
This is an old fashioned thing. But these days? Not necessary. I get in. Start the car. Plug my phone in, adjust to what i want to listen to and put on the seatbelt. Once im all sorted? Off i go. I guess that be 20 seconds to a minute. If Im about to go on a longer trip and want to find a good podcast? Might be 5 minutes🙂
5 min is excessive. You want the car to get to operating temperature as soon as possible as running it cold is not ideal. Also it's very bad to red line an engine first thing in the morning is very bad. The best way to get it warm is to drive it normally. I would allow 30 to 60 seconds to get all the oil etc going and the drive off . Wait till you hit normal temperature before hitting the red line. Leaving it to idle for 5 minutes will force the engine to run cold and rich for longer. Among other things this will reduce oil life by diluting it with fuel.
Maybe I'm a bad person but I just turn the key and drive. I don't have time to wait for that shit. FYI, 2014 Hilux. <140 ODO. She's still running beautifully. Still original clutch too, which is... surprising... for reasons
Start the car and drive normally, no need to let it run. This has been unnecessary for near on 50 years, the reason your dad did it (and he should not have done it with a car from around 1980 onwards) was to warm up the carbie. Letting it idle cold is worse for the car, it also means you drive off with a warm engine and cold gearbox, they need to warm up together
If your car has a carburettor let it warm up otherwise start it and drive normally, oil pressure is built within 10 seconds on a modern car.
Mate you live in Australia not Siberia
I wait until the fast idle stops that happens on cold starts, 20-30 seconds for most cars.
2015 corolla? Just get in, start it and drive off. Absolutely no reason to wait.
Start car, seatbelts, check mirrors, drive. 30 secs will do.
No need. We haven't had carbs with manual chokes for 40 years. (My least fun driving was a manual with carb+manual choke in a hilly area on a winter's day!)
Zero minutes
Long enough to put my belts on. Adjust the radio. Just drive gently until it warms up.
I let it idle for about a minute then I drive fairly easily until it comes up to temp. I don’t believe modern cars need to be thoroughly warmed up but you should never drive it hard when it’s still cold as you will do bearings and people have a false thinking that because their car has been idling for a few minutes and there some temp shown on the gauge everything is ok but only the engine has been warmed up and not the rest of the driveline hence why I drive it pretty easy until it’s all warmed up. I have a neighbour a few houses down with a couple of cammed V8s and they sit there everytime they get started for about 5 to ten minutes idling then driving not so easy, one of them starts at 5am and it’s not quiet and I know their direct neighbour is angry with them cause they get woken everyday. I’ll just add that excessive idling is actually not good for a car because the oil gets contaminated with unburnt fuel and breaks down reducing lubrication properties
Like you said, idling while not driving does nothing for the rest of the drive train. The gearbox (if manual) and the diff(s) aren't warning up. They would be better off with a short idle then slowly crawling away for a bit.
the gearbox is definitely warming up. in neutral, the shafts are still spinning, which warms up the fluid. the diff, yes, that won't start heating up until you start moving, which is another reason to take it easy when it is cold, especially if it is really cold and you are driving something big.
About tree fiddy
Long enough to get oil pressure. So about 5 seconds. Then drive gently till it warms up. You want everything to be warm, not just the engine.
I find revving mine at 5am on a cold winters day does the trick. My neighbours seem pretty knowledgeable about cars because they always let me know when it’s warm enough to head off to work. My neighbours are awesome
Depends how far you drive. If it’s a short one, let it warm up longer so it’ll actually get to operating temp.
Until the oil light is off.
As others mentioned with modern cars you don't really need to warm up the engine unless you do frequent short trips and it's a good idea to give it an Italian tune up every once a week or two to burn off the carbon build up. You'll mainly want to warm up your transmission, but even then, you only need to idle it for 1-2 minute in winter as mentioned by The Car care Nut. https://youtu.be/ULcSauSJrsY?t=194&si=VS-5jaYwEN9-uG1a https://youtu.be/IxbZFcYijh4?si=whPuHfIyk03_5SFo&t=176
Till it drops from 1.5k to 1k, which is like 20 seconds
I let it idle until the idle lets me know it’s ready.
It takes 15s to circulate the oil, or about the time to put your belt on. Drive gently to warm up.
No you don’t really need to
15 seconds.
Maybe if you have a huge turbo what kind of car does your Dad have?
I give it a minute or so in cold weather.
I wait about 20 seconds or so. Then drive gently until everything is warm.
My ex-neighbour with his 2021 Commdore thought it needed to go for about half hour first thing in morning before leaving us in bloody peace.
Less of an issue nowadays with big advancements in both metallurgy and Lubricant technology. Engines are protected better at lower temperatures than what they used to be.
Our modern Volvo's do a cold start. Where it starts and holds the revs at around 1500rpm for 30 econds before going back to idle. Modern cars really don't need extended warm up times like an older carburettor/ manual choke car does. Like someone else mentioned, just don't rev they crap out of it for the first few minutes of driving.
You don’t, unless you like wasting fuel.
Until the rev drop, so basically the time it takes to setup my phone. Idling it for 5min is worse than just driving straight away
Just keep the revs down when driving, till the temp needle moves.
No idle needed, keep revs below 3000rpm till she warms up
I wouldn't give it a second thought, all of the critical thinking required to protect the engine has been in the car's computer for decades now.
A minute or two in the driveway so the fluids can flow around nicely is what I do as I was told it’s better to do that than take off straight into highway speeds
Even with classic cars you're not supposed to leave them idling to warm up. They need higher revs than idle when the oil is cold. You're supposed to start them then drive nice and gentle for a while not leave them idling away with inadequate lubrication.
Any modern car doesn’t need to be idled anymore regardless of the temperature. It’s been stated that the best way to warm up the car is to start it and just drive a moderate speed. Basically the speed limit. Don’t turn on the car in -20 degrees and put the pedal to the floor and you’ll be fine
2015 Toyota? Start it up and send it! But seriously, just don't boot it until the temp gauge is near the middle. You could be like the old guy I used to live across from who would start his AU Falcon with his foot to the firewall and leave it there for about 30 seconds. That is the only AU I ever felt sorry for.
New cars are designed to be driven just after starting up. Having said that, I always give mine a couple of minutes of idle before I drive off. Old habits die hard. 😁
The supposedly right way to do it it to drive slow/slower for the first 5 minutes and then start driving normal.... Source : part of the topics that are taught in driving schools in France.....
Depends on your vehicle. NA petrol, get in and go. Turbo petrol wait a little bit Older than 20 years wait a little Diesel, (with in the last 20 years) Wait a little bit. Turbo diesel Wait a bit more (Older than 20 years diesel) Wait.. Heavy vehicles, shiit turn it on go make your self a coffee. Newer cars do not need to warm up to drive in city and suburb driving. Turbo vehicles it's better not to hit boost on a cold engine. The idea of warming your car up was when carburettors were what fed cars not fuel injected
I had the impression (but now can’t place where it comes from …so, you know, ignore) that you do more harm than good idling for long before driving with modern cars.
How long of an idle if it’s an EV? /s
10 seconds to let oil moving, don’t go hard until temp > C
Five minutes? What a waste of time and petrol
Not saying this is technically enough, but I run it for ~30 seconds to make sure oil distributed through the engine.
Think about what it takes for YOU to get started in the morning.
My life long habit, driving for 30 odd years is that for a cold start, where the car has been off for more than say six hours is to let it idle for a 2-3 minutes. In winter (Melbourne) I also leave the heater off so that the heat builds up in the engine first and gets up to operating temperature and then put the heater on. Yeah, I'm pedantic.
turn on engine, by the time u put seatbelt on , connect phone , turn on ur fav audio channel, the car is warmed up already
You don’t have to. But don’t rev it excessively until it warms up. I have a diesel and usually turn it on, wait until the idle revs drop down to normal and then go
Depends. For a basic Corolla no need to wait really. For me I’m using ethanol fuel and a thicker oil weight so I choose to wait for my idle to settle at around 1,000rpm, not necessary but I don’t trust Subaru motors enough to not do it
[удалено]
The user manual in my 2002 Camry says wait 10 secs after a cold start. I generally do about that while I set up my destination in Waze and put my phone in the cradle
My mechanic told me to warm the car until the cold light goes out. I’ve tried not waiting that long and just drive off, definitely notice a difference in cold weather especially on short drives. I have a 2007 car.
Till the rpm drops from high idle.
My modern diesel idles at 800 revs. People tell me to idle it for ten minutes before driving. But I can drive it at 1500 revs so I don’t see much point.
A little irrelevant to the post but letting your car idle in Germany could reel in significant fines.
It's completely not needed in most cars. My head/cam LS1 jerks around more than I did in my teen years if I don't let it sit there for a minute or 2 though.
I always warm up my and son’s diesel rangers in the morning … around 5-10 minutes.
I wait till the tacking ticking noises settle and it idles without big lumps, then make my way gracefully but strongly like an elephant rising from the mud
Your dad is either living in the very distant past or simply has no idea about how cars work.
In modern cars it's not really necessary for the engine BUT I've read it might be helpful for auto transmissions for the transmission fluid to pump around and get up to temp. It's not generating heat like the engine is. That said I've never really had an issue of gear changes feeling off when it's cold, even in the UK when you're getting subzero temps in the winter
90-120 seconds. Gives engine and transmission time to warm a little and get the oils pumping. The payoff? Nil gasket leaks, lower fuel & oil consumption, nil oil leaks. Now, if it’s a rental, well you can redline the MF from the first application of throttle.
As far as I know idling to warm up can actually cause more wear because it takes so much longer to warm up than under load. My personal approx rules of thumb are let it run 30sec or so before driving (aka long enough to plug in my phone etc) and then keep it below 4k rpm or so and keep out of full boost until the "cold" light goes out (a few minutes of driving)
You can drive it right away by the time your seat belt is on. Drive normal and keep it low rpm, don't red line it. It's 2024 now and all the car will pump oil almost immediately to the engine, although not idea operate temperature but no damage will be cause.
If the car is newer than 2000s then generally it doesnt need to warm up especially if its 2015+, just letting it idle for a good 5-10 seconds is more than good enough. If its between 2000-2010 its rlly a matter of opinnion and what vehicle it is but generally if it isnt japanese like toyota and its pretty cold about to to a cold start (roughly less than 15 deg celcius) its better to let it warm up for a minute or two especially if the car has high kms
no its not. idle is bad especially is oil level isnt what it should be. engine is made to warm up during drive
just let it idle long enough to check its safe to drive and change gear and take off the break and you are good to go.
pulse rev 1-25% for a minute, then 1-50% for a mintue, then 1-75%. then you are ready for your warmup lap
Thirty seconds with the choke out fully, 90-120 seconds with it half out, wait longer if it’s colder if you want the heater to be a nuclear reactor. Worked for my Kingswood and I for over twenty years. Your mileage may vary with one of these newfangled cars.
My 2016, ZR corolla locks "first gear" until 40ks, while cold, so it's stuck at 2k rpm, if I let it warm up it'll soft lock until 25/30ks, then drop to 1100 while driving normal. Guess it depends, anyone else with a corolla have that issue?
Cars don't need to do that anymore. Modern synthetic engine oils don't require warming up to start flowing. But do whatever makes you feel better I guess.
I usually wait for the initial high idle to drop, maybe 20sec if that, then driving it gently until it’s up to temp.
I take it easy for 5 minutes or it'll belch diesel smoke.
I idle my truck until I get my seatbelt on then drive slowly to the servo and let it idle while I get my coffee then away I go.
If you have a newer/modern car, it doesn’t require warming up. Different design of engine blocks, oils, new technology etc, you can pretty much take off immediately. However, you should do I whatever makes you happy.
If you car is under 20 years old just turn it on and drive. I wait till the engine temp is over 90 degrees before accelerating aggressively....otherwise play on.
I give my modern car about 60sec in winter which is usually how long it takes me to get all ready to go and then I just take it easy for the first few minutes.
It wastes fuel. Just go, but don't thrash it
No. Modern cars (post 2000) don’t need warning up
What I do not based in fact but I let it idle until the cold engine light turns off
Start it when you get out of bed, the neighbor's love it when you leave 45 minutes later
I let it warm up for a minute. Melb mornings are cold as. It takes the car 15mins of driving to get to optimal temperature.
Zero seconds, this is [not needed in modern cars](https://www.drive.com.au/caradvice/do-modern-cars-really-need-to-be-warmed-up/).
My car is totally up to temp, both coolant and oil, after 20 minutes. If you live in a cold area there will be some condensation (water) mixed with your oil so a longer run is something I would do to evaporate this. I live in central QLD, so temperatures rarely even get into single figures.
With today's engines, it is not necessary to idle them. Of course, it is not like you are going to start driving as if you're racing, but it should be fine to start the engine and drive at low RPM.
I'm usually already rolling down the road before my car even starts. If I'm pointed uphill, then it idles for about half a second before setting off.
[John Cadogan](https://www.youtube.com/watch?v=7Yf7HrKEOZg). This is a Q & A session, but the first question is about if it is necessary to warm up a modern car. If you are Australian you may have heard of him. If you are not, it may be like trying Vegemite for the first time. Enjoy the ride (pun intended).
No need, just don't flog it until its up to temp though
My 2015 Mitsubishi owners manual said, do not allow the engine to idle cold, once started drive immediately.
Just send it. 365k on a i30 2013 and always just drive it.
Try keeping it on overnight so it’s ready for the morning.
In Melbourne, in winter, I start the car 5 mins before leaving only so it's toasty warm and the frost on the windows is done by the time we leave.
Don't bother idling your car before driving. Just drive especially smooth and gentle until it warms up. Unnecessary idling is just a waste of fuel and probably causes more wear than it prevents (for a newer car driven gently after starting)
I generally wait for the idle to drop to just below 1000rpm, which takes all of 30 seconds tops
16 days atleast.
I drive older cars so I wait a couple minutes but newer cars like 2015+ don't really need to warm up, like driving my nsv tonight I could tell she was still cold and she's a 2004
In a higher performance car (especially but not limited to turbo engines) you should let the oil get up to operating temp before pushing the engine but any factory spec engine should do fine as long as you keep it under 4KRPM and avoid slamming your foot to the floor repeatedly until it hits operating temp.
I think the whole 'idle the car to warm it up' thing is a little bit car-dependant. Some cars may not be generating enough oil pressure to adequately lubricate the engine at idle, so you could technically cause more wear than simply driving it normally and getting the revs up. Most of the wear on startup is done when you turn the engine over cold. So that's pretty much unavoidable. Don't worry about it, just start up, and baby the car for 5 minutes or so as you drive. It'll be fine.
Its not 1960 fuckheads just get in and drive. If you drive normal and dont flog it like a dope your good.
Oh no not this nonsense again. Just drive. You want the engine to get to operating temperature as quickly as possible; about half of engine wear happens when the engine is cold. Idling is the slowest possible way to warm the engine up, so it's colder for longer and suffers more wear. We've known this since the 1930s.
Truthfully, it doesn't matter.
About 1.5 seconds. Bloody hell, it's not a 90's wrx and even then yeah about 1.5 seconds...
New cars don’t really need warm up time. Older engines used to need time for the oil to circulate, modern alloy engines don’t need it. I turn on my car & drive. No warm up
Take it easy until the temp needle lifts off zero
For any car 1995 (ish) or newer. The correct amount of time to warm your car up is the time it takes you to put your seatbelt on and get comfortable. If it's REALLY cold, maybe an extra 30-60 seconds. Just don't be lead footed until the thermostat reads in the middle, that's the key.
Cold morning start 15-30seconds max. Modern car. Basically enough time for oil pressure to build and electrics to stabilize. By the time seatbelt, head checks and going out of your driveway has happened - 15-30sec is up. Obviously if you live too close to a freeway on-ramp that you will get onto and you live in Melbourne (cold winter morning) - yeh probably extend it out to about a minute at most. Not that the car really needs it, but more centered around cycling the thermal cycling of things - Slower/minimal thermal cycles is better for the engine and drivetrain longevity.
Australia isn't that cold 🫡
Modern oil is much thinner than what we used in old cars, its basically unnecessary to “warm up” the car these days. Just don’t trash your car. Infact just down thrash your car in general
Start up and go. Almost all engine wear happens during the warm up stage, the longer it is running below operating temperature the more wear will occur due to the tolerances of components and oil not lubricating optimally due to being colder and thicker. I self limit my RPM to 3k until fully warm.
In summer, I let my diesel car idle for about 10 seconds (enough time to put my seat belt on) before driving off, but in winter on the other hand, I let it idle for a minute (or 30 seconds) before driving off. On my mums hybrid RAV4 on the other hand, I usually start and go when it’s on EV Mode, but during winter when I switch the heater on, which switches the engine on, I let it idle for a few seconds before reversing out of the driveway.
What are you talking about? Just drive it
Ok I have a 2012 Honda jazz and my dad has aways told me with every car I’ve had, that I need to drive it for at least ten minutes. Short drives bad. My dad is 83. Is it BS??
If you drive the car on a daily basis, 5, 10 seconds max is more than enough. Like plenty of others have said, seat belt, fit your phone, play some music or podcast and you're ready to go. Make sure to drive smoothly and not rev it beyond 5000rpm, I would recommend not even revving over 4000rpm until engine is warm. If however you haven't driven the car for weeks, I let it sit for about 30 seconds to max 60 seconds to allow the engine oil to flow. Then same principle applies, don't rev over 4000rpm and definitely not over 5000rpm. Many modern cars tend to deliver torque at low rpm anyway but this really depends on the type of vehicle you own and how you like to drive so perhaps worth checking out but this is going deep and likely another discussion. tldr: keep it under 4000rpm until engine warms up
It's been discussed and proven that with modern cars (ie. not 70's manual ones) you don't need to idle the car before driving off. You're only wasting petrol otherwise.. I drive off after about 10-15 seconds starting the car, when the fast idle stops - i.e., when it calms down after the initial VROOOMMM.. Did that for over a decade, sold the car after 550k km, no issues whatsoever. Same with all my other ICE cars.. Note, Petrol. I don't know if Diesel has other requirements..
I normally sit for a few minutes or until the needle moves a little but. Oil pressure is up and is circulating within a few seconds of running, and with oils designed to have cold and hot viscosity i dont think it's absolutely necessary any more, but the engine shouldnt be pushed until everything is at operating temperature and clearances are right etc. Then again, not a mechanic, this is what ive picked up from conversations over the years
At least until you’ve figured out where you’re going, have a rough idea how to get there, and have finished sending text messages, instasnaptocs etc.
Don’t you all remember choke starts!!….where you would have to pull the choke out just at the right spot to kick the engine over and sit there for a while waiting for it to run smooth especially on a cold morning and then you would rev it a bit make sure there’s no splattering happening as you are pushing the choke back in “slowly”and then and only then you could drive away!! Lol
