Engine oil Mobil or OEM Toyota

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.

My 2014 had 226K changed it at toyota every 10K no issues

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.

I'm apparently the least informed person here (never done an oil analysis), but FWIW I seem to be fine with Mobil-1 0w40 on a 996.2 with 208k miles.

Throughout the summer I was averaging a quart every 750-1000 miles, still using Mobil1 15w50 & Viscoplus. This winter it dropped back down to 1 quart every 500 miles, but as the weather has warmed up, my consumption seems to have decreased again. I think that had something to do with the oil, which was admittedly way too thick for cold weather. I would let the car warm up a couple minutes before driving because that oil is syrup in cold weather.

DO NOT use Mobil1 0W40 in the 2.5. I tried it and well before the oil change time, the engine sounded like a diesel with all sorts of valve train rattle.
