Whatever you use, make sure it has the zinc additives. Many of the companies had to switch because of the new govt. laws which caused a lower zinc level. If it is marked racing and NOT FOR STREET USE, then it should be fine.
Some I like:
Red Line
Alisyn
Royal Purple
Joe Gibbs
Champion
Cen-pe-co is another I have heard is good.
