I've run Valvoline Synpower, Pennzoil Platnium, and am currently using Q horsepower. I will say that the Pennzoil Platnium is the best oil I have used so far. The Q horsepower is holding up well for having 50 passes on it this year and the oil pressure still hovers around 40 at hot idle. I'm switching to Castrol on the next oil change with the K&N filter(Advanced Auto special ftw!)
