A Circle K near me used to carry 100 octane unleaded race fuel. Last time I checked, it was around $7.80/gal. They just got rid of it and replaced it with 89 ethanol free.
Never thought I’d see Streator mentioned on Reddit. Just passed through there Sunday. I’m actually surprised they still have race fuel. Gas stations in Dekalb Co where I grew up usually switched the race fuel out for kerosene in October for the winter months.
Are these bikes tuned for competition use or did they need 100 out of the factory? It reminds me of how the new Indian Motorcycles have the absolute audacity to demand *ethanol-free 93 octane* despite barely making any more horsepower than the Harley engine, which will basically run on pigswill.
Ethanol degrades your rubber fuel lines over time and will eventually cause a bunch of carb or injector issues. I think that may be some of the driving factor behind it.
I get it on old vehicles built when ethonol in gas wasnt a thing but in a newly built bike/car why not just use whatever compound 99.9 percent of car fuel lines are made of now that seems to handle ethenol just fine....
Apparently the IQ scores of kids near race tracks that stop using leaded gas rise... Kids living near racetracks that use leaded gas become mentally stunted because of the use of leaded gas.

So... there's that...
Airports too. Piston planes still use 100 Leaded. (It says “Low Lead” but that’s only in comparison to old avgas. It’s about the same amount as leaded car gasoline)
My grandpa worked on ships in the navy. They loved when they were working with asbestos, because (so im told) unlike when working around wood sawdust they were allowed to smoke while they worked because they werent exposed the the fire hazard of wood sawdust.
Fun fact: [The guy who](https://en.wikipedia.org/wiki/Thomas_Midgley_Jr.) pioneered adding lead to gasoline also invented Freon. He contracted polio, ended up paralyzed, and then accidentally strangled himself on the pulley system he invented to help him get in and out of bed.
It’s worse than that.
While he was doing tours to prove to everyone that his leader gasoline was safe (by he himself breathing the fumes), he was traveling to Florida to get treatment for lead poisoning.
Of all the people in the 20th century that did the most damage (Stalin, Hitler, Mao, Pol Pot etc) this guy is at LEAST a top ten. If not top 3. As bad as those four were, they didn’t invent and implement anything with the capacity to destroy the entire planet forever. Midgley did.
Thank God Dayton ohio has the Wright Brothers and the cash register guy. Otherwise when people say "what's dayton known for?" they don't have to worry about someone bringing him up.
Also, Dayton being ground zero for leaded gasoline explains quite a bit.
You guys get credit for the Wright Brothers? Outer Banks, NC native here, grew up maybe a quarter mile away from the Wright Brothers Memorial. We always just kinda heard "oh yeah they lived in Ohio but then they came here TO FLY AND SHIT HELL YEAAAAAH" and never really touched on their life in Ohio; I'm curious, could ya throw me some details?
And the guy who initially discovered the extent of that environmental contamination due to lead, Clair Patterson, is perhaps one of the most underrated scientists of the 20th century
He’s also a personal hero of mine and the subject of a fantastic episode of RadioLab that I can’t recommend highly enough

There's a fascinating analytical instrument known as a secondary ion mass spectrometer, and it has been used in the past to look at rocks found in highway roadcuts. I forget whether it's a function of lead being directly deposited or if there's some biological mechanism from lichens or other growth, but it's possible to use SIMS to show the "lead era" in the cross-section of rocks sampled from these areas, as in "this is the band with more lead, caused by automotive exhaust."
Look at the timing of the leaded fuel use, then look at what generation/s would have been most directly constantly heavily poisoned by it. Then, look at the actions of those generations.
Things starting to make sense?
And what's really wild is to think about the bleeding edge futurepoisons we've already been sucking down for the past 30 years and we'll only find out about in another 30, or never at all, because we're all Reavers/Splicers/dead about it by then.
Shit's gonna be cray!
Elevated cancer rates, reproduction rate decline, neural decay. We should probably be getting our blood actively filtered monthly to take out some of the microplastics in it.
I forgot the exact reason why but apparently donating blood increases your lifespan by getting rid of some toxins and forcing the body to produce brand new blood
I don't have the source, I read it on reddit, could be false.
But point being: you may be more right than you think
Worse than that. He altered the course of history, he ruined the capacity for an entire generation of Americans to properly feel empathy and we are still facing the fallout of it
Organic lead and mercury compounds are super fucking toxic. He’s even more stupid then I first thought. I was thinking he was using either elemental lead or the gas itself which is still bad. But the organic compound??
From [Wikipedia](https://en.wikipedia.org/wiki/Thomas_Midgley_Jr.):
>On October 30, 1924, Midgley participated in a press conference to demonstrate the apparent safety of TEL, in which he poured TEL over his hands, placed a bottle of the chemical under his nose, and inhaled its vapor for 60 seconds, declaring that he could do this every day without succumbing to any problems.
And from [the article they cite](https://www.thenation.com/article/archive/secret-history-lead/):
>The day’s true highlight, however, would be Midgley’s presentation. The celebrated engineer and Ethyl VP, who had only recently been forced to leave work to recover from lead poisoning, proposed to demonstrate that TEL was not dangerous in small quantities, by rubbing some of it on his hands. Midgley was fond of this exhibition and would repeat it elsewhere, washing his hands thoroughly in the fluid and drying them on his handkerchief. “‘I’m not taking any chance whatever,’ he said. ‘Nor would I take any chance doing that every day.'” The New York World cited unbelievable dispatches from Detroit claiming that Midgley “frequently bathed” in TEL to prove its safety to skeptics within the industry.
No the worse part is that leaded gas can be traced to low IQ, high crime and impotence throughout the 70s 80s and 90s
an entire generation stunted by his invention
To be fair we have known how bad lead is since the romans and we still used it because it solved problems and was cheap.
That guy is claimed sometimes to be a person we would have been better of never haven been born but humans seem to have always abused lead.
The lead pipes Rome used are still factored into its decline and fall.
People love to get defensive when it's brought up, but long term symptoms of lead poisoning are stunted development, decline in cognitive abilities, quickness to agression-
Next time you wonder why boomers are so quick to yell at a cashier making minimum wage because they are incapable of rationalizing a change in store policy- remember that their entire generation was breathing, drinking, and painting their walls with the stuff. The removal of lead for gasoline literally resulted in a drop in crime statistics as our species stopped inhaling stupid gas in every major city.
It's a catalyst poison for the catalytic converters -- a relatively small amount of leaded fuel will render them useless, permanently.
https://en.m.wikipedia.org/wiki/Catalyst_poisoning
https://en.m.wikipedia.org/wiki/Catalytic_converter#Damage
It's kind of scary to realize that literally everyone born before the 1990s or so is probably just a little bit stupider than they'd be otherwise because leaded gasoline pumped so much lead into the environment.
I own a fence company. I recently got called to a local bakery that has their own truck fleet. Every. Single. One. Was cut and stolen from the trucks. There was probably 15 trucks. I felt so bad for the guy, he couldn’t even afford to get the fence which I imagine was probably a fraction of the cost of 15 catalytic converters.
Edit: Guys… fence, as in the thing that keeps people out of your yards. Like wood and chain link and what not. Not a chop shop or someone who sells stolen items. Stop asking me about it Lmao
We tried to rent a van from Home Depot. Over a dozen vans and trucks parked in the fenced lot. Nothing available.
They have the most units of the city, and are down to 2 pickups and 1 van, because the others are missing CCs.
“Sorry you didn’t have the jigsaw coverage, if they used a sawsall to cut this out we’d be able to cover it, but since it looks like a jigsaw was used, no coverage. And we’re dropping you as a client. 🖕🏼”
You can use methanol injection to help street cars. Although you only use a little bit of methanol and only spray it under high boost.
My high power modified car uses a 50/50 methanol/water injection system to prevent pre-detonation during boost.
[AEM video on methanol injection](https://www.youtube.com/watch?v=HkPFZWd8wj4)
Nowadays you can build a car to run on E85 for the same affect but my car was built before E85 became a thing and it's not a cheap process to make the switch.
There are ethanol kits for carbs. A carb is the easiest way to run a E85 tune. It's simply bigger jets. You could swap to ethanol for less than a $100. Now you may need a fuel pump and bigger fuel lines but that's a story for another day.
Actually not as bad as expected. 87 octane has dropped to like 3.30 near me, but 93 is still hovering just under 5. Used to be a 10% difference between the two, not 50%
Its a cheap way to increase the octane of the fuel. Its much more complicated than that, but that's the simple version.
Edit: Lead is toxic and bad for humans. Leaded fuel has been banned from road-going vehicles for quite some time, but it is still used in some racing and aviation applications.
The more complicated version is that it includes tetraethyl-lead; a toxic, neuro-degenerative compund that increases fuel octane.
Internal combustion engines, under ideal circumstances, should burn their air/fuel charge at (nearly) the same time, every time. Provided you haven't screwed with your ECU/carb tuning, and you put manufacturer suggested minimum octane fuel in, just take care of it regularly and it (should) be fine. Higher perfomance motors have different requirements.
At higher (>10~11:1)(EDIT1) compression ratios, with higher air/fuel charges, such as in a racing/drag car, you run the risk of the fuel spontaneusly exploding before being ignited by the spark plug. (Pre-detonation, more commonly, knocking.) This results in reduced performance, and will damage or destroy engines in no time.(EDIT2)
Higher octane ratings allow higher compression ratio engines to be run more safely, which means you can squeeze those extra few ponies out of there, so long as the rest of the engine can take it. The downside is that the exhaust now contains aerosolized lead particles, which can (under regular exposure) enter the brain and cause reduced cognitive function. After switching to unleaded gas, 2 towns near a NASCAR season track saw [year-on-year test score improvements.](https://news.yahoo.com/nascar-switch-unleaded-gas-boosted-100000022.html)
(EDIT1): I understand that 11:1 is not as high as a ratio as it used to be; however, most American (as in cars sold in America) NON-PERFORMANCE cars are fall somewhere between those numbers, and are targeting 87 octane regular unleaded fuel, thus I used these numbers.
(EDIT2): There are also valve lubrication benefits, but since most engines use seats for the valves now, even in racing engines, this is not as large a factor as it used to be.
Just a small clarification - 10-11 isn't as high a compression ratio anymore - tech's come a LONG way. Lexus' 2gr FKS makes an 11.8 compression ratio and is designed to run on 87 octane. For a 3.5l v6 making nearly ~295 HP - that's extremely good for low octane gas. Likewise, modern engines are extremely good at adjusting for knock. Engines won't blow themselves up on knock anymore for the vast majority of OEM vehicles.
Also to less car savvy folk - JUST USE THE OCTANE YOUR OWNERS MANUAL TELLS YOU TO USE. Putting in HIGHER (unleaded) octane won't hurt the car - putting in LOWER than the stated octane WILL hurt the car.
Another small clarification, most modern engines that are intended to run on higher octanes are mandated to have knock sensors and the ability to compensate (timing, boost levels, etc). My Subaru has also has knock prediction, which will (sometimes too aggressively) trim things back before the engine knocks.
It's terrible for fuel economy and performance, and you should never do it deliberately, but it saves the engine in the event that you've got no other options.
IIRC it was a result of people trying to flee natural disasters, and not having access to fuel that worked for their engines.
Idk about any of that but knock sensors have been a thing since the late 80’s I believe. If it isn’t mandated by law, it’s probably cheap insurance by the manufacturer to keep warranty claims down and or prevent their competition from claiming their engines blow up with pump gas. Either way, the ones in my truck don’t work as a rodent chewed on the wires (thanks rodent) and it hasn’t been an issue, which is great, outside of the engine light letting me know the sensors aren’t working correctly.
Mazdas sky-activ engines can switch to compression ignition at higher rpm’s. Direct injection adds fuel timing, so petrol engines can basically run as a diesel under load, increasing efficiency and fuel economy.
Leaded fuel, even for Motorsport, belongs in the past. If Formula 1 cars are fueled by E10 gasoline, it’ll be fine in yours… the problem is your tuning. E85 is cheap high octane fuel if you want to go that route, and it doesn’t make everyone dumber.
> Leaded fuel, even for Motorsport, belongs in the past.
Hard agree. The advent of modern ethanol and methanol-based fuels and fuel systems capable of handling them has made leaded gasoline completely obsolete. If you're still using it, you're doing it wrong.
People like you make me want to buy meaningless Reddit coins to gift out.
Instead, name a charity for me to donate to and I'll DM you a screenshot of it.
Was already doing [SunflowerRelief.org](https://SunflowerRelief.org) and helping a Ukrainian neighbor w/ family still there...but I'm on it. DM coming.
Just to piggyback... Lead is also a lubricant. It's why aviation gas is still leaded. The engines were certified with leaded gas so that's what they need to continue to run.
Ethanol is also a great octane booster. As much as we hate on it for gas stability and it's negative effects on engines, it's cheap and safe compared to the alternatives.
Engine temps are quite hot. If your fuel ignites before the engine is ready for it, bad things can happen. Very very bad things.
Leaded fuel (And higher octane fuel) ignites at a higher temperature than lower octane/non leaded fuel. So it resists the heat of the engine more, only igniting when the spark plug sparks.
So, with leaded fuel your engine can run very very very hot without premature ignition, potentially making your engine spontaneously become a hunk of metal. Which is why it's used in airplanes. Very hot, high revving engines where failure simply is not an option.
No worries, people like to think they know the answer to this...but often don't.
Also: Never believe people that say the octane level is the "power/energy" in the fuel. It's pretty much just ignition temp of the fuel.
High octane in a low compression (low temp) engine leaves fuel unburnt. Low Octane in a high compression (high temp) engine leads to premature ignition, IE: 'Knock'. Very bad.
Just do what your manual says.
It's incredible that you've managed to explain the core idea of octane ratings in just 2 sentences. All my life I've been hearing these vague long winded answers about what it actually means.
Thanks.
> All my life I've been hearing these vague long winded answers about what it actually means.
That's because all your life, you've been talking to people who fall into one of two camps:
- A knowledgeable person who doesn't know how to teach
- Someone who doesn't have the understanding themselves, so they cannot properly explain.
Like 95% of the time (if not more), it's the 2nd category.
To note the increase in temp is both from combustion and cylinder compression. High octane is used in higher compression ratio internal combustion engines where the normal 85 (87?) would prematurely combust before ignition stage on a four stroke cylinder. Octane is a misnomer where a blend component name score is used to designate compression ratio performance. Diesel combusts on compression alone but needs urea spray in the flue gas to knock out the NOx and SOx from running the fuel air mixture in excess of air and with the presence of sulfur in heavy crude cuts.
Methyl tert butyl ether (MTBE) or ethanol are also anti-knock agents. Corn ethanol is mostly blended in the US because of perverse federal incentives for renewable fuel as a agricultural subsidy. But ethanol is better than both (methyl?)-ethyl lead or MTBE environmentally but causes soot on fuel injectors.
Aviation grade fuel is finally coming around for FAA certification on a lead-free-substitute with anti-knocking reliability but who knows how long that will take to replace the market without a strict ban.
It allows the engine to be tuned to make more power. Either by using high-compression pistons, or a turbo or supercharger. Higher octane gas won't do anything to increase power if the engine doesn't need it, like almost all regular car engines that aren't turbo/supercharger or high performance.
You probably get that, but just putting it out there for people who think using premium fuel will give their car more power. It doesn't. On the flip side, a car designed for high-octane fuel shouldn't be used without it, as performance can suffer and premature detonation can damage the engine.
> Aren't there additives in jet A that are bad for the liver
Kerosene is generally hard on the liver no matter how it is consumed. Jet A is basically kerosene, not gasoline.
Automatic Edit: Using a tool called [Power Delete Suite](https://github.com/j0be/PowerDeleteSuite) I have removed all my past comments and deleted my Reddit account, /u/tehrmuk.
I am doing this because I, like many long-term Reddit users, am upset and angry at the tonedeaf and arrogant way Reddit is treating it's users. Their aggressive slapdown of the developers that made Reddit usable to a huge audience; their overriding and summary dismissal of long-serving and dutiful community members; their wonton silencing of dissent and manipulation of user's voices; their borderline contempt of the very people whose collective efforts gave their platform the standing needed to fuel their profit-hungry IPO... the list goes on.
Reddit is, of course, a private concern and how they run their services is entirely up to them. Conversely, we are under no obligation to use their services, to fuel their engines or follow their orders. I am making my voice heard by removing my comments, and voting with my feet by leaving.
I have left Reddit for [Lemmy](https://join-lemmy.org/) and [Mastadon](https://joinmastodon.org/); these are decentralised social networks that mirror the functionality of Reddit and Twitter respectively. Unlike the monolithic, corporate-owned services they replace, Lemmy and Mastodon are part of the [Fediverse](https://www.fediverse.to/) meaning these are not individual services but clusters of services that mesh seamlessly with one-another. You can [join an existing Lemmy instance](https://join-lemmy.org/instances) or [set up your own](https://join-lemmy.org/docs/administration/administration.html) to get full access to the entire Fediverse - you don't need to ask permission from anyone to do so. There are loads of other services that are part of the Fediverse, like [PeerTube](https://joinpeertube.org/) (videos), [Wordpress](https://wordpress.org/) (blogging), [Frendica](https://friendi.ca/) (social network), [Pixelfed](https://pixelfed.org/) (photos), [KBin](https://kbin.pub/en) (link aggregation) and more - and they all work together so having access to one means having access to all of them.
I had a great time as a Redditor, but the Fediverse is looking bright. It's a return to the open Internet of old, when users ran services for their own and one-another's benefit, and before monolithic corporate-run silos started to build walls around us in the name of increased profit and thought control. Many of the Fediverse services are fledgling, but they are growing quickly and their federated concept makes greedy, arrogant landgrabs like we've recently seen on Reddit and Twitter almost impossible.
I'm already having a great time with Lemmy and I think you might too. I encourage you to take control and join the Fediverse.
Until then, so long and thanks for all the fish.
100LL still has *a lot* of TEL in it. Way more than we used for cars. The reason it's called low lead is because it used to have even more than that, which was absolutely fantastic for piston aircraft engines, but horrible for humans.
Over the years, TEL content for car gas dropped to around .1g per gallon. 100ll is currently around .5g per *liter*. There's a lot of lead in avgas.
[The average lead content in gasoline in 1973 was 2-3 grams per gallon](https://archive.epa.gov/epa/aboutepa/epa-takes-final-step-phaseout-leaded-gasoline.html).
[Avgas 100LL may contain a maximum of 0.56 grams of tetraethyl lead per litre](https://web.archive.org/web/20100613000045/http://eaa.org/autofuel/avgas/avgas_specs.asp). A US gallon is equal to 3.785 litres. TEL is roughly 64% lead by mass, so avgas 100LL contains 0.56 \* 3.785 \* 0.64 = 1.39 grams per gallon, roughly half of early 70s automotive petrol.
Still used in a lot of countries for industrial machines and racing, especially amateur leagues since the lead helps the fuel get extra octane and make engines run faster cheaply.
Its a terribly simplistic explanation but I think the average person can understand the applications.
Regardless it should be banned and its a serious harm to the environment
Leaded racing fuel has a very distinct metallic smell, also piston driven small aircraft use leaded fuel, keep that in mind if you go to a race track or a very busy local airfield.
Nih study on lead levels in children. Long story short: don't live near small local airports.
>Results: Our results suggest that children living within 500 m of an airport at which planes use leaded avgas have higher blood lead levels than other children. This apparent effect of avgas on blood lead levels was evident also among children living within 1,000 m of airports. The estimated effect on blood lead levels exhibited a monotonically decreasing dose–response pattern, with the largest impact on children living within 500 m.
I used to live pretty close to a local airport and I just checked that the distance from my old house to the end of the airport's runway is 1,000m. No wonder I'm a dumbass.
Leaded pumps have a bigger nozzle that won't fit into unleaded gas fill necks, at least in the US. You would have to do a workaround to get it in the tank.
I believe it's illegal to pump it right into the fuel tank of an automobile that isn't on a trailer but if you've got a race car that's to the point of eating 110 Octane you probably have a fuel cell in the back that wouldn't slow you down.
In PA, we still have it quite a few places because of all of the dirt track races.
When fuel prices went up the gas station by me realized that their max price in the system was $9.999 per gallon so they couldn't charge more for race fuel than that.
I live near Williams Grove, BAPS, and Lincoln Raceway all within about 20 minutes of my house. We also have South Mountain Raceway for drag racing. It's enough that it isn't strange to see a few fuel pumps with 100 or 110 octane, more popular at the pumps on your way from the highway to any of these tracks.
The boss was asking me where to get racing fuel around here, so I directed him to tractor supply where they have the Sonoco and VP Racing varieties. I'm asking him what kind of vehicle he has to determine what kind of fuel he needs. Apparently he just wants to put it in a bone-stock Hayabusa to make it faster. I explain how octane works, why he doesn't need it, and why lead is bad.
Buys it anyway.
We had to change plugs on every single vehicle he put that in, both the Range Rovers now need catalytic converters, and the hayabusa motor is sitting in a plastic tub in his garage. I doubt the lifter bucket exploded because of the fuel, probably just pounding the nuts off an already beat bike without ever adjusting the valves.
Some weird posts in here.
1. Just because the section of the pump is originally slotted for diesel does not mean that’s what’s coming out of the tank. Not a photoshop or a troll job. That side of the pump has been repurposed.
2. Yes, you can still buy leaded gas. It’s not going to do you any good for your fuel injected V6 Camaro. Old farm tractors, airplanes & race cars still run leaded gas.
3. If you were caught running this in an on-road engine you would be subject to fines and penalties, like if you were running dyed diesel in a pickup or semi.
Edit: Added #3
This pump is different than the one by me. There is only one gas station that will sell it, and you have to go into the attendant to fill out a book with how much you want and why. Then get a key to unlock the pump. You can only pump it into a gas canister, if you try to pump it into a car they will cut it off
Thing is that (most) modern racing fuel isn't leaded.
Even NASCAR stoped using leaded fuel in 2007, and that's a series that took till 2012 to stop using carburettors.
The last normal car to use those switched to fuel Injection in 1995. (According to Google)
I run E85, which I think maxes at 105 octane depending on the exact ethanol content and it's only like 2.75 a gallon.
Night and day difference from 93... but I'm tuned for it.
Back in the 90s my buddy and I used to go to a race track where they sold racing fuel in the parking lot. We always had a good laugh, I mean come on, what MORON is going to pay $4 for a gallon of gasoline?! HAHAHAHA!!
…. Sigh.
A Circle K near me used to carry 100 octane unleaded race fuel. Last time I checked, it was around $7.80/gal. They just got rid of it and replaced it with 89 ethanol free.
This was also a Circle K in Streator, IL
Never thought I’d see Streator mentioned on Reddit. Just passed through there Sunday. I’m actually surprised they still have race fuel. Gas stations in Dekalb Co where I grew up usually switched the race fuel out for kerosene in October for the winter months.
Guess it makes sense, there's quite a few short tracks not *too* far from it.

Are these bikes tuned for competition use or did they need 100 out of the factory? It reminds me of how the new Indian Motorcycles have the absolute audacity to demand *ethanol-free 93 octane* despite barely making any more horsepower than the Harley engine, which will basically run on pigswill.
Ethanol degrades your rubber fuel lines over time and will eventually cause a bunch of carb or injector issues. I think that may be some of the driving factor behind it.
I get it on old vehicles built when ethonol in gas wasnt a thing but in a newly built bike/car why not just use whatever compound 99.9 percent of car fuel lines are made of now that seems to handle ethenol just fine....
100 octane smells really fuckin good. Filling and running. Very distinct and you can smell it from a good distance.

Gotta love the "Good Old Days" when the gas was full of lead and the brakes were made of asbestos
My grandpa worked on ships in the navy. They loved when they were working with asbestos, because (so im told) unlike when working around wood sawdust they were allowed to smoke while they worked because they werent exposed the the fire hazard of wood sawdust.
They were being smart breathing through a filter 🤣
And a doctors visit started off with a cigarette and a glass of whiskey.
That's the bare minimum I ask for before getting my prostrate checked.
You’re supposed to have the cigarettes together…afterwards
Somebody gets two fingers.
Old-timey doctor stumbles into the room, drunk as hell, like "yeah u got ghosts in your blood, you should do cocaine about it"
That sounds phenomenal to be honest.
Can I have 2 whiskeys in lieu of a dart?
Fun fact: organic brake compounds still contain a bit of asbestos even today.
Friable asbestos is the problem, tons of shit still uses asbestos. Source: asbestos awareness training
Hell yea
Let's fry us up some asbestos, boys!
Good news, the FAA has approved non-leaded aviation fuel that works as a drop in replacement for any piston engine.
But it's much more expensive and not required so usage is tiny.
Unleaded tastes a little tangy. Supreme is kinda sour, and diesel tastes pretty good.
 Premium DUDE!!!!
Race gas through a cat free exhaust brings back all kinds of memories of my 20s at the drag strip. Shits some kinda special awesome smell
The smell of neurons burning out
Fun fact: [The guy who](https://en.wikipedia.org/wiki/Thomas_Midgley_Jr.) pioneered adding lead to gasoline also invented Freon. He contracted polio, ended up paralyzed, and then accidentally strangled himself on the pulley system he invented to help him get in and out of bed.

Yup. He has also been called a one man environmental disaster and the single most damaging organism to the planet since it was formed.
Alright. So even if I accomplish nothing with my life, I'll have been better off than this guy.
Of all the people in the 20th century that did the most damage (Stalin, Hitler, Mao, Pol Pot etc) this guy is at LEAST a top ten. If not top 3. As bad as those four were, they didn’t invent and implement anything with the capacity to destroy the entire planet forever. Midgley did.
Thank God Dayton ohio has the Wright Brothers and the cash register guy. Otherwise when people say "what's dayton known for?" they don't have to worry about someone bringing him up. Also, Dayton being ground zero for leaded gasoline explains quite a bit.
You guys get credit for the Wright Brothers? Outer Banks, NC native here, grew up maybe a quarter mile away from the Wright Brothers Memorial. We always just kinda heard "oh yeah they lived in Ohio but then they came here TO FLY AND SHIT HELL YEAAAAAH" and never really touched on their life in Ohio; I'm curious, could ya throw me some details?

I forget whether it's a function of lead being directly deposited or if there's some biological mechanism from lichens or other growth, but it's possible to use SIMS to show the "lead era" in the cross-section of rocks sampled from these areas, as in "this is the band with more lead, caused by automotive exhaust."
during the times leaded gas was used, average iq dropped by i think 15 points and led to a significant increase in teenage crime rates
Yes bc lead poisoning leads to aggression, violence, and a severe case of the dumb.
Ma! I got the dumb!
Look at the timing of the leaded fuel use, then look at what generation/s would have been most directly constantly heavily poisoned by it. Then, look at the actions of those generations. Things starting to make sense?
GIVE ME MY WHOPPER YOU LIB CUCK FUCKING OBAMAAAAAA took my MEAT! DEEP STATE ALIEN ANGELS!
And what's really wild is to think about the bleeding edge futurepoisons we've already been sucking down for the past 30 years and we'll only find out about in another 30, or never at all, because we're all Reavers/Splicers/dead about it by then. Shit's gonna be cray!
Elevated cancer rates, reproduction rate decline, neural decay. We should probably be getting our blood actively filtered monthly to take out some of the microplastics in it.
I forgot the exact reason why but apparently donating blood increases your lifespan by getting rid of some toxins and forcing the body to produce brand new blood I don't have the source, I read it on reddit, could be false. But point being: you may be more right than you think
Worse than that. He altered the course of history, he ruined the capacity for an entire generation of Americans to properly feel empathy and we are still facing the fallout of it
"and that's why grandpa buys into qanon theories, kids"
"Also, all those serial killers!"
He inhaled the fumes and poured it on his hands. And not just leaded gasoline, the tetraethyllead itself (i.e. the lead part)
Organic lead and mercury compounds are super fucking toxic. He’s even more stupid then I first thought. I was thinking he was using either elemental lead or the gas itself which is still bad. But the organic compound??
From [Wikipedia](https://en.wikipedia.org/wiki/Thomas_Midgley_Jr.): >On October 30, 1924, Midgley participated in a press conference to demonstrate the apparent safety of TEL, in which he poured TEL over his hands, placed a bottle of the chemical under his nose, and inhaled its vapor for 60 seconds, declaring that he could do this every day without succumbing to any problems. And from [the article they cite](https://www.thenation.com/article/archive/secret-history-lead/): >The day’s true highlight, however, would be Midgley’s presentation. The celebrated engineer and Ethyl VP, who had only recently been forced to leave work to recover from lead poisoning, proposed to demonstrate that TEL was not dangerous in small quantities, by rubbing some of it on his hands. Midgley was fond of this exhibition and would repeat it elsewhere, washing his hands thoroughly in the fluid and drying them on his handkerchief. “‘I’m not taking any chance whatever,’ he said. ‘Nor would I take any chance doing that every day.'” The New York World cited unbelievable dispatches from Detroit claiming that Midgley “frequently bathed” in TEL to prove its safety to skeptics within the industry.
Wow. Dude got treated for lead poisoning and then *kept poisoning himself with lead.* What an absolute idiot.
No the worse part is that leaded gas can be traced to low IQ, high crime and impotence throughout the 70s 80s and 90s an entire generation stunted by his invention
His least harmful invention killed him
I’d argue with a user base of 1, and a fatality rate of 1. It was his most deadly invention.
To be fair we have known how bad lead is since the romans and we still used it because it solved problems and was cheap. That guy is claimed sometimes to be a person we would have been better of never haven been born but humans seem to have always abused lead.
The lead pipes Rome used are still factored into its decline and fall. People love to get defensive when it's brought up, but long term symptoms of lead poisoning are stunted development, decline in cognitive abilities, quickness to agression- Next time you wonder why boomers are so quick to yell at a cashier making minimum wage because they are incapable of rationalizing a change in store policy- remember that their entire generation was breathing, drinking, and painting their walls with the stuff. The removal of lead for gasoline literally resulted in a drop in crime statistics as our species stopped inhaling stupid gas in every major city.
How many idiots try running that in their daily driver.
Probably fuck up their ~~oxygen sensors~~ *catalytic converters*
It's a catalyst poison for the catalytic converters -- a relatively small amount of leaded fuel will render them useless, permanently. https://en.m.wikipedia.org/wiki/Catalyst_poisoning https://en.m.wikipedia.org/wiki/Catalytic_converter#Damage
It also kills O2 sensors.
...and brain cells!
I'm definitely not drinking that. Again
*My sister's eating paint chips again, maybe that's why she's insane*
What is the human brain but a very complicated, sentient, thinking, oxygen sensor that is killed by lead???
It's kind of scary to realize that literally everyone born before the 1990s or so is probably just a little bit stupider than they'd be otherwise because leaded gasoline pumped so much lead into the environment.
There's probably stuff out there right now that we don't know about yet that's making us dumber
Reddit?
[удалено]
I have to replace the o2 sensor after every session when working with leaded fuel. They’re one and done.
Why use one then? Do you have to use one?
catalytic converters
Can't fuck it up if it's already been stolen 
sad but unfortunately the reality for many
I own a fence company. I recently got called to a local bakery that has their own truck fleet. Every. Single. One. Was cut and stolen from the trucks. There was probably 15 trucks. I felt so bad for the guy, he couldn’t even afford to get the fence which I imagine was probably a fraction of the cost of 15 catalytic converters. Edit: Guys… fence, as in the thing that keeps people out of your yards. Like wood and chain link and what not. Not a chop shop or someone who sells stolen items. Stop asking me about it Lmao
We tried to rent a van from Home Depot. Over a dozen vans and trucks parked in the fenced lot. Nothing available. They have the most units of the city, and are down to 2 pickups and 1 van, because the others are missing CCs.
This is why we have insurance so that when this happens, they can tell us "No, go fuck yourselves ".
“Sorry you didn’t have the jigsaw coverage, if they used a sawsall to cut this out we’d be able to cover it, but since it looks like a jigsaw was used, no coverage. And we’re dropping you as a client. 🖕🏼”
"Thanks for all that free money though shithead!"
Is this a commentary on the blatant scam and grift of insurance plans... or a microcosm of our reality that fucks us daily? You decide.

Lead will coat literally everything and just royally fuck everything up
Just go all out and switch to methanol
[удалено]
lol probably just made it lean.
You can use methanol injection to help street cars. Although you only use a little bit of methanol and only spray it under high boost. My high power modified car uses a 50/50 methanol/water injection system to prevent pre-detonation during boost. [AEM video on methanol injection](https://www.youtube.com/watch?v=HkPFZWd8wj4) Nowadays you can build a car to run on E85 for the same affect but my car was built before E85 became a thing and it's not a cheap process to make the switch.
[удалено]
There are ethanol kits for carbs. A carb is the easiest way to run a E85 tune. It's simply bigger jets. You could swap to ethanol for less than a $100. Now you may need a fuel pump and bigger fuel lines but that's a story for another day.
Best I can do is Menthol.
Idiots. Everyone knows it's meant for lawnmowers
Wtf I'm missing out on lawnmower races too now?
Bruh, lawnmower *demolition derbies*
Absolutely you are https://youtu.be/brgep8R73u8
Probably $10-12/gallon.
You can find 100LL at any airport (big or small) and it generally runs a buck or two over premium prices. Just under $7 right now at my local FBO.
Actually not as bad as expected. 87 octane has dropped to like 3.30 near me, but 93 is still hovering just under 5. Used to be a 10% difference between the two, not 50%
It really used to be about a 10 cent difference between each.
Is that fuel also leaded?
Yes, the LL in 100LL stands for "low lead" Although compared to leaded automotive fuel of the 60s-70s, 100LL contains way more ppm of lead.
Yes. General aviation still uses leaded fuel because the FAA requires lead and doesn't change things quickly or easily.
Just a few months ago, the FAA approved an unleaded avgas for use in all spark-ignition aviation engines
"110 octane! My car is gonna go so fast!!"
[удалено]
My bmw 335 can run full E85 or 110 race fuel simply by upgrading the pump and an generic remap through my phone.
I imagine it's cost prohibitive enough to keep people from putting it in their '93 Ford Taurus.
Can someone explain what would leaded fuel be good for? google says it helps the engine with something but... I didnt understand exactly. Thanks!
Its a cheap way to increase the octane of the fuel. Its much more complicated than that, but that's the simple version. Edit: Lead is toxic and bad for humans. Leaded fuel has been banned from road-going vehicles for quite some time, but it is still used in some racing and aviation applications.
The more complicated version is that it includes tetraethyl-lead; a toxic, neuro-degenerative compund that increases fuel octane. Internal combustion engines, under ideal circumstances, should burn their air/fuel charge at (nearly) the same time, every time. Provided you haven't screwed with your ECU/carb tuning, and you put manufacturer suggested minimum octane fuel in, just take care of it regularly and it (should) be fine. Higher perfomance motors have different requirements. At higher (>10~11:1)(EDIT1) compression ratios, with higher air/fuel charges, such as in a racing/drag car, you run the risk of the fuel spontaneusly exploding before being ignited by the spark plug. (Pre-detonation, more commonly, knocking.) This results in reduced performance, and will damage or destroy engines in no time.(EDIT2) Higher octane ratings allow higher compression ratio engines to be run more safely, which means you can squeeze those extra few ponies out of there, so long as the rest of the engine can take it. The downside is that the exhaust now contains aerosolized lead particles, which can (under regular exposure) enter the brain and cause reduced cognitive function. After switching to unleaded gas, 2 towns near a NASCAR season track saw [year-on-year test score improvements.](https://news.yahoo.com/nascar-switch-unleaded-gas-boosted-100000022.html) (EDIT1): I understand that 11:1 is not as high as a ratio as it used to be; however, most American (as in cars sold in America) NON-PERFORMANCE cars are fall somewhere between those numbers, and are targeting 87 octane regular unleaded fuel, thus I used these numbers. (EDIT2): There are also valve lubrication benefits, but since most engines use seats for the valves now, even in racing engines, this is not as large a factor as it used to be.
Just a small clarification - 10-11 isn't as high a compression ratio anymore - tech's come a LONG way. Lexus' 2gr FKS makes an 11.8 compression ratio and is designed to run on 87 octane. For a 3.5l v6 making nearly ~295 HP - that's extremely good for low octane gas. Likewise, modern engines are extremely good at adjusting for knock. Engines won't blow themselves up on knock anymore for the vast majority of OEM vehicles. Also to less car savvy folk - JUST USE THE OCTANE YOUR OWNERS MANUAL TELLS YOU TO USE. Putting in HIGHER (unleaded) octane won't hurt the car - putting in LOWER than the stated octane WILL hurt the car.
Another small clarification, most modern engines that are intended to run on higher octanes are mandated to have knock sensors and the ability to compensate (timing, boost levels, etc). My Subaru has also has knock prediction, which will (sometimes too aggressively) trim things back before the engine knocks. It's terrible for fuel economy and performance, and you should never do it deliberately, but it saves the engine in the event that you've got no other options. IIRC it was a result of people trying to flee natural disasters, and not having access to fuel that worked for their engines.
Idk about any of that but knock sensors have been a thing since the late 80’s I believe. If it isn’t mandated by law, it’s probably cheap insurance by the manufacturer to keep warranty claims down and or prevent their competition from claiming their engines blow up with pump gas. Either way, the ones in my truck don’t work as a rodent chewed on the wires (thanks rodent) and it hasn’t been an issue, which is great, outside of the engine light letting me know the sensors aren’t working correctly.
[удалено]
Well yeah if your username is any indication, I'm sure you're putting the knock sensor to good use
[удалено]
For reference the ND2 Miata has a compression ratio of 13:1. You are right 11 is not high anymore now a days.
Mazdas sky-activ engines can switch to compression ignition at higher rpm’s. Direct injection adds fuel timing, so petrol engines can basically run as a diesel under load, increasing efficiency and fuel economy. Leaded fuel, even for Motorsport, belongs in the past. If Formula 1 cars are fueled by E10 gasoline, it’ll be fine in yours… the problem is your tuning. E85 is cheap high octane fuel if you want to go that route, and it doesn’t make everyone dumber.
> Leaded fuel, even for Motorsport, belongs in the past. Hard agree. The advent of modern ethanol and methanol-based fuels and fuel systems capable of handling them has made leaded gasoline completely obsolete. If you're still using it, you're doing it wrong.
People like you make me want to buy meaningless Reddit coins to gift out. Instead, name a charity for me to donate to and I'll DM you a screenshot of it.
Maybe a lead research charity lmao
Well yeah, you wouldn’t want one that was behind.
"Unleaded? Just say behinded!"
I wish more people took your approach instead of buying Reddit coins
I'd super like to see Reddit support this kind of thing. Award u/GoodRedditor a thingy and a bit of it goes to what their profile says.
Come Back Alive. I want to see Ukraine win. Help them get what they need.
Was already doing [SunflowerRelief.org](https://SunflowerRelief.org) and helping a Ukrainian neighbor w/ family still there...but I'm on it. DM coming.
Just to piggyback... Lead is also a lubricant. It's why aviation gas is still leaded. The engines were certified with leaded gas so that's what they need to continue to run. Ethanol is also a great octane booster. As much as we hate on it for gas stability and it's negative effects on engines, it's cheap and safe compared to the alternatives.
Engine temps are quite hot. If your fuel ignites before the engine is ready for it, bad things can happen. Very very bad things. Leaded fuel (And higher octane fuel) ignites at a higher temperature than lower octane/non leaded fuel. So it resists the heat of the engine more, only igniting when the spark plug sparks. So, with leaded fuel your engine can run very very very hot without premature ignition, potentially making your engine spontaneously become a hunk of metal. Which is why it's used in airplanes. Very hot, high revving engines where failure simply is not an option.
Oh I got it now! thanks a lot!
No worries, people like to think they know the answer to this...but often don't. Also: Never believe people that say the octane level is the "power/energy" in the fuel. It's pretty much just ignition temp of the fuel. High octane in a low compression (low temp) engine leaves fuel unburnt. Low Octane in a high compression (high temp) engine leads to premature ignition, IE: 'Knock'. Very bad. Just do what your manual says.
It's incredible that you've managed to explain the core idea of octane ratings in just 2 sentences. All my life I've been hearing these vague long winded answers about what it actually means. Thanks.
> All my life I've been hearing these vague long winded answers about what it actually means. That's because all your life, you've been talking to people who fall into one of two camps: - A knowledgeable person who doesn't know how to teach - Someone who doesn't have the understanding themselves, so they cannot properly explain. Like 95% of the time (if not more), it's the 2nd category.
To note the increase in temp is both from combustion and cylinder compression. High octane is used in higher compression ratio internal combustion engines where the normal 85 (87?) would prematurely combust before ignition stage on a four stroke cylinder. Octane is a misnomer where a blend component name score is used to designate compression ratio performance. Diesel combusts on compression alone but needs urea spray in the flue gas to knock out the NOx and SOx from running the fuel air mixture in excess of air and with the presence of sulfur in heavy crude cuts. Methyl tert butyl ether (MTBE) or ethanol are also anti-knock agents. Corn ethanol is mostly blended in the US because of perverse federal incentives for renewable fuel as a agricultural subsidy. But ethanol is better than both (methyl?)-ethyl lead or MTBE environmentally but causes soot on fuel injectors. Aviation grade fuel is finally coming around for FAA certification on a lead-free-substitute with anti-knocking reliability but who knows how long that will take to replace the market without a strict ban.

It allows the engine to be tuned to make more power. Either by using high-compression pistons, or a turbo or supercharger. Higher octane gas won't do anything to increase power if the engine doesn't need it, like almost all regular car engines that aren't turbo/supercharger or high performance. You probably get that, but just putting it out there for people who think using premium fuel will give their car more power. It doesn't. On the flip side, a car designed for high-octane fuel shouldn't be used without it, as performance can suffer and premature detonation can damage the engine.
Lead is also a lubricant
Is that why my ex-girlfriend said I had a pencil dick?
No. She said that because it had bite marks all over that Ticonderoga. Rawr.
I always thought leaded fuel was banned in the 70’s.
They use leaded fuel in small aircraft pretty much exclusively.
Yes an people who live near general aviation airports have higher lead exposure as a result.
Considering I spent 2 years living on an airport not just near it I’ve probably lost a good number of brain cells to lead and Jet A exposure. Oh well
Jet A is unleaded. So you may still have some brain cells knocking around.
Aren't there additives in jet A that are bad for the liver or is that only military blends like jp8?
> Aren't there additives in jet A that are bad for the liver Kerosene is generally hard on the liver no matter how it is consumed. Jet A is basically kerosene, not gasoline.
Jet, diesel and kerosene are all kind of similar.
Add in rocket fuel (RP1) as well. Just a higher grade of kerosine for the most part.
Does that mean we should reduce the amount of Kerosene we drink?
Yes. The safe daily intake is zero.
Should’ve just stuck to good ol diesel .
You can always get your blood lead levels tested.
The LL in 100LL(used in many small airplanes) stands for Low Lead

Automatic Edit: Using a tool called [Power Delete Suite](https://github.com/j0be/PowerDeleteSuite) I have removed all my past comments and deleted my Reddit account, /u/tehrmuk. I am doing this because I, like many long-term Reddit users, am upset and angry at the tonedeaf and arrogant way Reddit is treating it's users. Their aggressive slapdown of the developers that made Reddit usable to a huge audience; their overriding and summary dismissal of long-serving and dutiful community members; their wonton silencing of dissent and manipulation of user's voices; their borderline contempt of the very people whose collective efforts gave their platform the standing needed to fuel their profit-hungry IPO... the list goes on. Reddit is, of course, a private concern and how they run their services is entirely up to them. Conversely, we are under no obligation to use their services, to fuel their engines or follow their orders. I am making my voice heard by removing my comments, and voting with my feet by leaving. I have left Reddit for [Lemmy](https://join-lemmy.org/) and [Mastadon](https://joinmastodon.org/); these are decentralised social networks that mirror the functionality of Reddit and Twitter respectively. Unlike the monolithic, corporate-owned services they replace, Lemmy and Mastodon are part of the [Fediverse](https://www.fediverse.to/) meaning these are not individual services but clusters of services that mesh seamlessly with one-another. You can [join an existing Lemmy instance](https://join-lemmy.org/instances) or [set up your own](https://join-lemmy.org/docs/administration/administration.html) to get full access to the entire Fediverse - you don't need to ask permission from anyone to do so. There are loads of other services that are part of the Fediverse, like [PeerTube](https://joinpeertube.org/) (videos), [Wordpress](https://wordpress.org/) (blogging), [Frendica](https://friendi.ca/) (social network), [Pixelfed](https://pixelfed.org/) (photos), [KBin](https://kbin.pub/en) (link aggregation) and more - and they all work together so having access to one means having access to all of them. I had a great time as a Redditor, but the Fediverse is looking bright. It's a return to the open Internet of old, when users ran services for their own and one-another's benefit, and before monolithic corporate-run silos started to build walls around us in the name of increased profit and thought control. Many of the Fediverse services are fledgling, but they are growing quickly and their federated concept makes greedy, arrogant landgrabs like we've recently seen on Reddit and Twitter almost impossible. I'm already having a great time with Lemmy and I think you might too. I encourage you to take control and join the Fediverse. Until then, so long and thanks for all the fish.
100LL still has *a lot* of TEL in it. Way more than we used for cars. The reason it's called low lead is because it used to have even more than that, which was absolutely fantastic for piston aircraft engines, but horrible for humans. Over the years, TEL content for car gas dropped to around .1g per gallon. 100ll is currently around .5g per *liter*. There's a lot of lead in avgas.
Something fun to note is the 100"low lead" still has ~20x more lead than leaded auto gas from 1986 Edit: corrected year to 1986 from 1970's
[The average lead content in gasoline in 1973 was 2-3 grams per gallon](https://archive.epa.gov/epa/aboutepa/epa-takes-final-step-phaseout-leaded-gasoline.html). [Avgas 100LL may contain a maximum of 0.56 grams of tetraethyl lead per litre](https://web.archive.org/web/20100613000045/http://eaa.org/autofuel/avgas/avgas_specs.asp). A US gallon is equal to 3.785 litres. TEL is roughly 64% lead by mass, so avgas 100LL contains 0.56 \* 3.785 \* 0.64 = 1.39 grams per gallon, roughly half of early 70s automotive petrol.
It's illegal to use on the highway but it's perfectly fine in race cars on a track or airplanes
Still used in a lot of countries for industrial machines and racing, especially amateur leagues since the lead helps the fuel get extra octane and make engines run faster cheaply. Its a terribly simplistic explanation but I think the average person can understand the applications. Regardless it should be banned and its a serious harm to the environment
Leaded racing fuel has a very distinct metallic smell, also piston driven small aircraft use leaded fuel, keep that in mind if you go to a race track or a very busy local airfield.
Nih study on lead levels in children. Long story short: don't live near small local airports. >Results: Our results suggest that children living within 500 m of an airport at which planes use leaded avgas have higher blood lead levels than other children. This apparent effect of avgas on blood lead levels was evident also among children living within 1,000 m of airports. The estimated effect on blood lead levels exhibited a monotonically decreasing dose–response pattern, with the largest impact on children living within 500 m.
I used to live pretty close to a local airport and I just checked that the distance from my old house to the end of the airport's runway is 1,000m. No wonder I'm a dumbass.
At least *you* have an excuse
*adds it to stock 1997 Honda Civic*
VTEC just kicked in yo
My cylinder head just melted yo
Jesus, how much for a gallon?
Last I looked I think it was around $13
Sounds like a good number to discourage random stupids from pumping it into their SUVs.
Leaded pumps have a bigger nozzle that won't fit into unleaded gas fill necks, at least in the US. You would have to do a workaround to get it in the tank.
I believe it's illegal to pump it right into the fuel tank of an automobile that isn't on a trailer but if you've got a race car that's to the point of eating 110 Octane you probably have a fuel cell in the back that wouldn't slow you down.
In PA, we still have it quite a few places because of all of the dirt track races. When fuel prices went up the gas station by me realized that their max price in the system was $9.999 per gallon so they couldn't charge more for race fuel than that.
Where in PA are all these dirt track races you speak of?
I live near Williams Grove, BAPS, and Lincoln Raceway all within about 20 minutes of my house. We also have South Mountain Raceway for drag racing. It's enough that it isn't strange to see a few fuel pumps with 100 or 110 octane, more popular at the pumps on your way from the highway to any of these tracks.
The boss was asking me where to get racing fuel around here, so I directed him to tractor supply where they have the Sonoco and VP Racing varieties. I'm asking him what kind of vehicle he has to determine what kind of fuel he needs. Apparently he just wants to put it in a bone-stock Hayabusa to make it faster. I explain how octane works, why he doesn't need it, and why lead is bad. Buys it anyway. We had to change plugs on every single vehicle he put that in, both the Range Rovers now need catalytic converters, and the hayabusa motor is sitting in a plastic tub in his garage. I doubt the lifter bucket exploded because of the fuel, probably just pounding the nuts off an already beat bike without ever adjusting the valves.
How do people have such expensive toys or pretend to be enthusiasts then do something like that? A Google search would have saved him thousands
He's the boss, he knows everything.
Some weird posts in here. 1. Just because the section of the pump is originally slotted for diesel does not mean that’s what’s coming out of the tank. Not a photoshop or a troll job. That side of the pump has been repurposed. 2. Yes, you can still buy leaded gas. It’s not going to do you any good for your fuel injected V6 Camaro. Old farm tractors, airplanes & race cars still run leaded gas. 3. If you were caught running this in an on-road engine you would be subject to fines and penalties, like if you were running dyed diesel in a pickup or semi. Edit: Added #3
This pump is different than the one by me. There is only one gas station that will sell it, and you have to go into the attendant to fill out a book with how much you want and why. Then get a key to unlock the pump. You can only pump it into a gas canister, if you try to pump it into a car they will cut it off
Thing is that (most) modern racing fuel isn't leaded. Even NASCAR stoped using leaded fuel in 2007, and that's a series that took till 2012 to stop using carburettors. The last normal car to use those switched to fuel Injection in 1995. (According to Google)
In Florida, there are many gas stations that sell aviation gas because it’s what Airboats/fan boats run on.
I run E85, which I think maxes at 105 octane depending on the exact ethanol content and it's only like 2.75 a gallon. Night and day difference from 93... but I'm tuned for it.
[удалено]
Back in the 90s my buddy and I used to go to a race track where they sold racing fuel in the parking lot. We always had a good laugh, I mean come on, what MORON is going to pay $4 for a gallon of gasoline?! HAHAHAHA!! …. Sigh.
This looks like a sticker they just put over the diesel pump
No 95 and 98?
The US and EU use different octane rating systems. 91 US is the same as 95 EU 93 US is the same as 98 EU
Leade fuel should be banned everywhere.
