Geo212 said:Royal Purple is said to have a %10 lower co-efficient drag because it has this thing called synecal. Supposed to give u about 5-10hp, never used it but Miata owners say there engines rev smoother and quieter with the switch. o 20w-50 is way to heavy, eats horses and gas mileage
Flat Black said:bulls***, synthetic oil doesnt increase its viscosity when its gets cold and sits in the crankcase, You could ******* run 50w100 in synthetic and it wouldnt harm anything. I've been running 15w50 Mobil 1 for months now.

Anyway, he said that the same truck fills Valvoline and the other with the same oil, and that Mobil has seperate/different oil.
He said that most oils are the same exact thing except for Mobil, I don't know how much I believe this, but I do know that I am going to go with Mobil.
so do you, according to the impressive list of cars youve got, tool.You drive a station wagon. Nuff said.
