Only reason I got off of Mobile1 is I was burning the ends off a couple of intake pushrods on cold starts. I was lectured about not having race oil with more zink. Race oil didn't help the pushrods, I had changed the lifters. Had to file a small groove to add oil upstairs. That fixed that. Just never did change back, but I think I will now. Have used up the race oil I bought. Mobil1 is much cheaper. I have also had very good luck with 5W20 Valvoline VR1 as well. If I have a heads up I'm concerned with, and I am feeling good (don't always anymore), and I think my rings are sealed up, I will still put Royal Purple zero-10wt in it. If ring seal is not good, that zero wt oil will slow you down. Ask me how I know. LOL
