what kind of oil for new rebuild
OK....I read the article that demon seed gave a link to for Hughesengines and they say to use a oil that is CI-4 or CI-4 Plus (Rotella T still falls in this rating if you check out their web site) in order to run with our flat tappet camshafts or use a oil of choice and add the additive that Hughes sell. That is fine and so that gives me two ways of protecting my cam.
Now if I go to Valvoline and check out their VR-1 Racing oil it dose not fall into CI-4 or CI-4 Plus rateing. Check it out:

Now I'm confused a little here. Would you guys go with what Hughes is saying and go with their additive and use my oil of choice or use Rotella T which seems Hughes is saying either is fine? But if I stick to what Hughes has to say then Valvoline Racing oil in out of the question. What do you guys think because my oil change is coming up soon?
