Rotella T and Delo 400 diesel oil work good as long as you can find some of the older stuff, I here the new diesel oil is going lower on the zinc also. I do know that Brad Penn racing oil works good, a friend of mine runs it in his stocker with alot of spring pressure and has had zero problems with his cam. We broke the cam in with Brad Penn and the GM EOS. But I'm sure there are plenty of other good racing oils to use. Shawn
