The ones you ought to consider are the ester based ones - Fuchs Pro S, Redline, Motul 300V, Millers CFS or Gulf Competition. They last a lot longer than other oils on track and give better protection. Lee, Rock oil is a basic option and although it's cheap, it really isn't very good. You'd be better off using one of the ester oils and getting the full use out of it (roughly 10 solid hours of track use). Even if the Rock oil is changed every session, the ester oils will be giving better protection even after several hours of use.
