Engine oil Mobil or IDEMITSU

I’ve been running mobil delay esp 5w40 it’s been working well for me.

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.

I will say I've done my last 3 oil changes with penzoil platinum and my engine rode rougher and louder than it did before with the Toyota oem oil. So this past time I tried mobil 1 and it's way quieter and rives smoother.

I'm running Amsoil 5w40 or Castrol Syntec 5w40. I ran Mobil1 10W30 a few times and I heard too much valve noise. When I opened the oil cap after driving around on the freeway it was smoking..which I'm not all that happy about. So I stopped using this oil.
