How is switching to synthetic Oil an upgrade? And how the heck does it make a car faster? Lol
do some research on royal purple or mobile1 and you find that the tighter compaced molecules alow moving parts to move free-er with less resistance. the crank does not have to try as hard when the oil in the pan is getting slapped all over the inside of the engine. (this makes less risistance) thus more hp, its only I tiny bit, but its there. I would recomend synthetic just for the life of the engine, not power or anything.
