Engine oil Mobil or OEM Audi

I've always put Mobil1 High Mileage in my 2013 Scion tC, IIRC Mobil1 is what Toyota uses at the factory. I had a heavy upper oil pan gasket leak that's largely stopped since switching to high mileage oil.

I use 0w40 Mobil 1 all year round. I live in upstate New York, so our winters can get pretty cold at times, and summers can be in the 90s F for days at a time.

My V70 2.5T is almost at 190k miles. I add about 1 quart of oil between oil changes at 5k intervals and my car has been trouble-free since I purchased it at 107k miles in 2017.

Do not cheap out on oil. I use Mobil 1 high mileage but Castrol is also good.

I've been using Mobil 1 0w-30 AFE in my VN for over 18000 miles now. No issues and runs fine.

I just rolled over 200,000 in my 2011 5.7. I change mine every 5,000 miles with Mobil 1 Full Synthetic High Mileage 0W-20.

Mobil1 V-Twin 20W-50 in all three holes.

I heard you can throw 20W-50 (Synthetic, specifically V-Twin Mobil One brand) in all three holes and have no issues.

Mobil1 x1 1000 15w40 in all my cars. My engines are clean and quiet, oil pick-ups don't clog, there's a nice permanent oil coating everywhere.

On my 1.8ts I usually change it when the motor blows up and has to be replaced. They used to last perpetually but builds have progressed to the "Yes it absolutely is going to grenade or window the block before 10k miles???? so really I only ever have to FILL oil 1 time???? I wish this was less true than it actually is. On the rest, (2.7tt and 4.2) 10k miles if you use good full synthetic oil and a nice filter

I burn 1 qt of Mobile 1 0-40 every 1000 miles.
