So I have been changing my oil with Motul 5w-40 x-cess 8100. Reason why is because all the local PCAR Cayman racers are using it. I have read that I should use an oil with a 80,000 psi or better and a high ZDDP rating. And I have not found any technical specifications listing Motul 8100. Anything better or stick with it?by JC Costarakis - Main Forum
