Enduro car, only run in summer/fall, engine loose, 300 laps on it, but doesnt smoke still when you whack it, ... really mostly what I have on hand and I like the smell of Valvoline
It is the racing one too, supposed to change 500 miles .. supposedly better lubrication. Never delved into the reason why. I like the smell of B+M Trickshift too
And Sunoco 260.
