Particularly the Supreme 7000 15w40 Synthetic Blend
I have a friend who has a hot rod shop and he has started carrying it this year and the Schaffer guy comes there and has his siminars. He also has a dyno and has dynoed cars just after a oil change and gained HP. :ast week he did a 350Z and got 6 more RWHP.. I run Royal Purple XPR 10w40 in my car mainly cause of the higher propertys of zinc and moly since I have a flat tappet and also use GM EOS with every oil change. For those who care here is a break down of all the oils Oils: What oil should I use? Which oil is best for my Porsche or aircooled engine? Just scroll down till you see the chart.
