Well, not exactly Larry. My Firebird is set up with a Vortech blower (that scavenges oil from the crankcase for lubrication) and Lingenfelter heads. It gets "used" alot in the summer on the street as well as at the track, therefore your sugestion of rerefined oil would be unacceptable. I subject my cars to extreme use but also pamper them with a lot of tlc. I take pride in being able to endorse products I believe in, and many manufacturers recommend this product by name. Paul
