That is alot like asking someone what they think makes a hamburger taste the best. So in no certain order -
Gibbs, Royal Purple, Brad Penn, Mobil 1, Rottella, Valvoline and probably many more.

I've used Schaeffer for 10 years and had not one single oil-related engine failure.

I have heard alot of good things about Schaeffer also.
