I switched to Joe Gibbs oil this year. I just bought a stock of it for next year. They have 30 wt Break in oil too. Best price so far is from a fellow SuperStock Racer. David Haag. He has an end of year sale going on right now 15% off of the Gibbs stuff he has. Shoot him an e mail if you need some oil. Jim
