on the market right now the two top rated synthetic oils (according to studies, I'm no expert) are Penzoil Platinum and Valvoline Synpower. The old Penzoil that use to leave build up is no longer. Penzoil out preformed almost every oil out there. I don't run Penzoil I'm a Valvoline fan. Here is a good website for all the studies and performance tests of oils. http://www.bobistheoilguy.com/
