It's phillips 66 . I was told it was 112 M. Well, a friend brings me the drum(1.5 hr drive), turns out its T-32 which is 106M and something like 112 R. I was really wanting to try my lubrant 26* race chip which calls for 110. All the info I've found instructs that the motor octane is whats important. Soooooo, do I take it back(arghhh ) or try it? I probably should call the buisness that sold it to me and discuss the situation. Anyone run this fuel?
