Comp Cams has a additive also which you get out of Summit. I have installed a new cam not to long ago myself and was told to use the Rotella-T, Valvoline VR-1 Racing oil or add a additive (GM EOS,Comp Cam,etc..) to my oil of choice. I went with the Rotella which I did the cam change in 06 before they did in changes in the oil. It was cheaper than the other methods. Now I really havn't thought about it but when the next oil change comes I think I'm going to go with the Valvoline VR-1. I know that we need more protection for our flat tappet cams than just throwing any oil in like everyone else. I was told this by these guys on here and some of them been around motors longer than I have been alive. Those that just pick a oil and go with it might be asking for trouble. I'd rather be safe than sorry.
