I'm not saying Mobil1 is the best, but it meets all the industry standards. I used it in three previous turbo engines and it always ran clean and never caused any problems. I do uoa every 20K and got well over 100K on the cars without oil burning, coking, engine wear or sludge.

Find one that works for you without busting your wallet.
