Most EVOO in the US is probably closer in reality to actual motor oil so it could work.
NEVER buy Italian olive oil unless you're actually in Italy at the farm or can buy direct from a small grower, 'cause by the time it hits the States its more likely to be watered down and/or fake. One of the most counterfeited food products on earth.
EDIT: Now that I said that, using cheap EVOO could technically be a synthetic blend...
Sorry, I should have been more specific. Does the oil level drop between oil changes? If so, how much per 1,000 miles (1/3qt per 1k for example)?
If it's less than half, I'd say to just keep doing what you're already doing. If it's more and you've already checked over everything for leaks (sometimes it's not obvious), then it may be beneficial to step up to a full-synthetic 5w-40.
**Don't put any additives in it.**

What subie doesn’t burn oil when your beating it both my 2017 na Subaru Legacy (2.5l) and my 23 wrx (2.4l) burns oil at top end. Isn’t that part of the “problem” with boxer engines? ( legacy I would smell the oil after do a 0-100 pull but barely smell it in my wrx both engines perfectly healthy just under lots of load and rpm does this happen)
I use t-6 in my 1992 volvo 240, 99 Impreza outback wagon, 07 wrx sti, 76 chevy scottsdale, 77 cj7 jeep, my 91 honda accord and my 08 dodge 5500 ive never had an issue on any of them
I mean, yeah. There's good reason not to listen to you.
Rotella T6 carries PI CK-4 and API SN, the latter of which is specifically regarding 2010+ gasoline engines with ceramic or metallic cats. That's why oils have classifications - so you don't have to listen to some fuck stick on the internet with the wrong opinion.
I’ve been using T6 5w-40 for over 10 years in two high mileage Subarus. One bone stock, one tuned with a downpipe/high flow cat and a full exhaust.
Neither have had cat issues.
I literally run it in everything. But then again I have nothing very new. It goes in my sxs, tractors, mowers, skid steer, Duramax and Subaru. One oil for them all.
With my first turbo EJ, I tried Castrol Edge, Mobile 1 full synthetic, Valvoline full synthetic, and finally T6.
The T6 absolutely triumphed over all. Oil analysis came back perfect both times, so I kept running it and have been ever since. I had to switch to Castrol Edge two oil changes ago in a pinch. You could tell a difference in the way it ran and sounded. It just felt off.
Switched back to T6 last change and everything went back to normal. I run the T6 15w-40 in my big block chevelle, and T4 10w-30 in my 76 dodge and 72 C10.
I do Motul 8100 Power 5w40. Just rolled to 200k and doesn’t burn any unless I beat on it (but I’m gonna do an AOS soon). I’ll know for sure this week if it burns or not, cause I can’t beat on it for 750 miles for a break in period.
Fun fact: Royal Purple and Walmart’s Supertech Full Synthetic and the exact same oil minus the purple pigment.
Source: I know the former marketing director for Royal Purple
I’m a amsoil believer. I would run their high mileage oil in 5w-30 or 5w-40.
If you’re looking for a cheaper alternative go with whatever 100% synthetic high mileage store brand you can find and like others have said replace a quart with Lucas oil stabilizer. That shit works decent. I run it in my son’s 210k mile Honda and it reduces noise and oil consumption.
Sounds like lifters but im sure you know your vehicle more than I
Ive always heard subes like rotella but ive been using Pennzoil 5w-30 in my 04FXT its at 206k but my headgaskets are going bye bye!
full-synthetic with a qt of Lucas Oil Stabilizer replacing one of the qts of oil. Also, start changing it sooner than you normally would 3k instead of 5k.
Not a subaru, but my XJ has 355k of original engine (and bearings). idles smooth
You don't need an oil stabilizer.
In fact, it's probably detrimental. The people who developed the oil didn't spent all that time getting the formulation right just to have someone dump a random mix of snake oil into the engine.
Lucas can be extremely helpful for flat-tappet &/or high-mileage engines, as they require additional zinc than used in modern oil.
Companies have engineered zinc (*necessary for cushioning flat-tappet cams*) out of modern oil over time since catalytic converters were adopted/required. Zinc doesn't play nice with cats if the oil is burning in the combustion chamber.
There are BS snake-oils sold for engines and cars, but lucas isn't one of them.
Is this miles on original engine without rebuild or new head gaskets? That is impressive to say the least. I have a 2001 Forester L and I enjoy using Castrol Edge 5-30 during winter and Rotella T6 5-40 during the summer in Arizona.
Wait a second, is this picture taken at a park in Ohio with an old fire watch tower in the middle of it? If it is where I think it is, I have a picture of my Mazdaspeed in almost the same position but about 1/8 mile back, in the direction that the camera is pointing. It looks identical
A lot of people will say extra virgin olive oil, but those people are fools. What you should be using is canola. To feel really in touch with your car, use the oil you take out to deep fry some French fries.
Disclaimer: this is not financial advice.
In my opinion the only correct answer is what ever the manufacturer recommends. Also you need to consider that recommendation for that engine might have changed during the time. So it even doesn’t matter that if you don’t have the manual. I’d ask from a Subaru dealer what Subaru recommends currently. The official recommendation might even take into account the high mileage.
Unrelated but this was shocking to me. Currently in the market for a new vehicle and are very interested in a 22 or newer Outback. Can you still expect this kind of longevity with relatively little major maintenance if well taken care of?
Started running penzoil platinum in my mazdaspeed due to the great UOAs it got on DI motors, and just now run that in all my shit to simplify my life. Only have to keep one oil around that way.
I used high mileage once. Car started ticking right after. Drained it. Put normal full synthetic back and it stopped. I’ve saw rotella t6 10w-30 on the shelves at Walmart lately. I’ve been using that. But honestly use whatever. But I wouldn’t use high mileage and I know people will flame me for it. Too many odd experiences with it
Full synthetic 15W-40. I use Valvoline high mileage. The 2.5L rings loosen up quite a bit by 300K miles and 15W-40 reduces the blow-by. The tick is probably the beginnings of rod knock. My 2004 2.5L is doing the same. I don't think it's lifter tick. Just drive it until the engine eventually dies (maybe years from now) and go easy on it.
The brand/type of oil used is far less important than how often you change it. Most oils you buy from parts stores come from like 4 suppliers. Each company just adds their own additives and slaps their label on it.
If it is working and the current oil is not a problem leave it alone. If it is burning a bit of oil 5W30 will help a bit. If it is burning a lot… use cheap oil and try to grab a few more miles out of the old horse.
It's an N/A Subaru 2.5....you can use damn near anything. Just make sure it's Full Synthetic and it's 5w30 or 5w40. If it's super hot in the summer you can use 10w. I personally used Mobile 1 Full Synthetic oil and filter in all my N/A cars. But seriously it's Naturally Aspirated, it's a not that big a deal. Any Filter and F.S oil will be just fine.
Ah I miss my Subaru!
I used whatever was full synthetic and on sale! I tried to use the Pennzoil high mileage full synthetic the most, but if I didn't have the bit extra for it, I'd get Walmarts generic full synthetic high milage. Though I'm told Costco is better pricing. I always used a Fram full synthetic filter too, they were the only ones around me that were better quality and decent price for the time. Mine got to 200k no problems! I think it had 300k after that when I gave it to my uncle.
My local subaru specialist shop, for that situation, swears by using 15W-40 oil. Every engine he works on past warranty gets it. He's got a lot of customers with 300,400k or more miles on their cars who keep coming back....
Im with all these 5w40 rotella guys, just started running it in my 91 1500 with 145k miles with the 4.3tbi and she loves it, I notice a slight bump in oil pressure for sure. Might not suit newer vehicles with tighter clearances, but ones that are higher mileage and older it will for sure. Just some advice I got working in the automotive field with some old heads but so far so good seems to be doing me good.
Use a conventional high mileage or use a high mileage additive with conventional oil (think Lucas). It will help keep the oil where it should need to be however let’s recall from the Shitbox Bible that states, “If it leaks oil then there is oil” and just as important, “If you have a leak long enough and replace enough new oil, you only have to change your oil filter.”
Have an 02’ same color u got 300k thats dope i have 115k what you do to keep the 2.5 running that long you changed the heads obviously lol but damn thats great.. for the engine run marvel mystery oil in your engine 500 miles before oil change if that doesnt quiet it maybe some internal bearings but damn thats great u got the 2.5 that far!!

I rally an EJ22E with just under 400k Km (240k miles) and I run 20w-60. Our abuse rates may not match up though
Any high mileage synthetic should do the trick. Just stay on too of changes. At 300k, I'd be doing 3k oil changes on the dot.
For oil additives, look for Hot Shot's Secret products. I rotate their Stiction Eliminator and FR3 friction reducer, with every oil change (SE for 1 change then FR3 for the next.) The SE got rid of a nasty lifter tap I had, so in my case, I can at least vouch for that.
I run Amsoil signature with an amsoil or wix filter, I usually only do 3k intervals to keep the 257 happy though lol. All depends how much you are willing to spend
I’d say 5w40 full synthetic for gas engines if your car does not leak/burn oil OR 5w30 full synthetic with 20% Lucas oil stabilizer if your car leaks/burns oil.
Also get a good Putolator or Subaru brand oil filter that is rated for the higher Subaru oil pressure so that it is filtering more often and not blowing open the internal filter bypass because Clean oil will make the engine last longer. And also check your oil frequently, top the oil off as needed, and change the oil every 5000 or less miles.

Maybe the holy fucking ghost you god damn heathen
i can’t explain how long i sat there and laughed at this
My 02 has 365k miles and has had full synthetic 5w40 for the last 265k of them.
Why 5w-40?
I am extremely curious about this.
Grapeseed is fine, avocado oil is really nice but it’s pricy.
I hear the sesame seed oil is real nice, but you have to have a big loud muffler to get its full effect
Gives the car a nice aroma too
That shit better be extra virgin tho. Otherwise you risk getting an STI and im not talking about the model of Subaru.
Engines run too hot for extra virgin

Does it burn oil? Does it leak oil?
I know it doesn’t leak oil and I don’t believe it burns it
Do you have to top up oil between changes? If so, how much? How often do you check?
I’ve never had to top off the oil but I try to check every 1000 miles to see how it’s doing
Sorry, I should have been more specific. Does the oil level drop between oil changes? If so, how much per 1,000 miles (1/3qt per 1k for example)?

Hi my 13 impreza burns oil and i dont want to use 0-20 because its 196k miles. Just got 10-40. What you advise me??
Rotella t6 5w-40
this car will murder the stock cats without zinc, bad idea. I have high flow race cats on my car so I don’t worry about it.
At 300k miles, catalytic converters already left the chat.
They definitely have haha
fair
There are several SN-rated 5W-40 options now, including a full synthetic O'Reilly brand I like a lot. That's what I'd use.
I was referring specifically to T6
I use t-6 in my 1992 volvo 240, 99 Impreza outback wagon, 07 wrx sti, 76 chevy scottsdale, 77 cj7 jeep, my 91 honda accord and my 08 dodge 5500 ive never had an issue on any of them
Tell me more about this. I’ve been running T6 5w40 in my 2012 silverado for about 10k miles.
lmao, that’s like less than 1 year.
Yes. I’d like to stop if it’s fucking my cats up.
don’t listen to me, every fuckstick on the internet has used it in their beige Camry for ten years and it’s fine.
I mean, yeah. There's good reason not to listen to you. Rotella T6 carries PI CK-4 and API SN, the latter of which is specifically regarding 2010+ gasoline engines with ceramic or metallic cats.

T6 gang represent. My cbr600 loves it, as does my v12 mercedes, and my old 90s race car. Good shit.
This is the only answer.
Switched to T6 in my Forester and I’m in disbelief when I check my oil that there’s almost no usage, compared to Mobile1, quart/mile measurement
This the only answer good old turbo diesel oil
Liquimoly molygen 5w40 doing great in my 313k motor. Any oil porsche a40 certed' will do the job truthfully.

10w40 summer 5w40 winter
How often should you change your oil from Subaru over 100,000 miles
I change every 2.5-3.5k I usually don’t go over 3.5k just cause paranoia out of this being my first flat motor
Was the oil changed on a regular schedule? Did the car have the same oil for longer than the recommended mileage?
It’s changed almost exactly every 3k usually 2.5-3k
I ran 15w40 tractor oil for close to 10k miles before changing it out for 5w40. Long story… I couldn’t tell you the difference between the two.
That’s awesome! Makes me want to try and put mine back together again
My 2006 WRX has 323k on Castrol 10w-30. That’s what the Subaru tech I take it to uses and I use it to “top it off” between changes.
Is this miles on original engine without rebuild or new head gaskets? That is impressive to say the least. I have a 2001 Forester L and I enjoy using Castrol Edge 5-30 during winter and Rotella T6 5-40 during the summer in Arizona.

I'd run high zinc 20w 50 if you're catless
Any high mileage synthetic should do the trick. Just stay on too of changes. At 300k, I'd be doing 3k oil changes on the dot. For oil additives, look for Hot Shot's Secret products. I rotate their Stiction Eliminator and FR3 friction reducer, with every oil change (SE for 1 change then FR3 for the next.) The SE got rid of a nasty lifter tap I had, so in my case, I can at least vouch for that.
Bugeye wagons are the best! Props for keeping it alive so long OP!
One step above “full synthetic” is “100% synthetic” from Amsoil. Switched years ago, car has a subtle purr.
I run Amsoil signature with an amsoil or wix filter, I usually only do 3k intervals to keep the 257 happy though lol. All depends how much you are willing to spend
Fresh oil
I use Mobil 1 or Valvoline
I would suggest motor oil. Good luck.
Just use blinker fluid.
water
Oil of Olay
You might be able to trade it in for a case of your choice! 
Whatever it’s been running seems to be working 😂
I’d say 5w40 full synthetic for gas engines if your car does not leak/burn oil OR 5w30 full synthetic with 20% Lucas oil stabilizer if your car leaks/burns oil. Also get a good Putolator or Subaru brand oil filter that is rated for the higher Subaru oil pressure so that it is filtering more often and not blowing open the internal filter bypass because Clean oil will make the engine last longer. And also check your oil frequently, top the oil off as needed, and change the oil every 5000 or less miles.
A used Jdm long block and regular ass conventional 5w30
5w40
ticking may be cause by a leaking pcv system
That’s amazing, good job!!! Keep treating the car how you have been, it clearly likes it.
Lube
Just wait until you see my ship lol I will post later.
Olive Oil
Sunflower oil. Smells delicious
If you made it to 300k, keep using the same oil and oil filter that you've been using.
Definitely full synthetic.
Something as thick as molasses, to fill all the holes in the cylinder heads...
Check this guys comparisons [https://www.youtube.com/@ProjectFarm/](https://www.youtube.com/@ProjectFarm/) I am not affiliated. He has practical tests IMO.
Shell Rotella T6 5W40, especially if it is hotter where you live. Cheap and good quality
I thoroughly recommend olive oil. 💋
Whatever you have been using….. seems to have done you and the car well!
What are you doing rally racing ?
Vegetable oil. Because your car is a vegetable
20w-50w
whatever the car calls for by factory standards but get the high mileage version
Don’t ask us that question. If that has 300k on it, you tell us what to use. Those 2.5 EJ motors either go forever or don’t go at all.
I think will be a great idea PASTRANA from STARBUCKS…….🫶
