Don't hurt yourself, Richard. Jeez. I'm hardly Mr Sunoco. I don't even use the stuff in my car. Maybe I read this wrong;
So either the race fuel was of benefit over PULP or it had gone off and the car ran like shit?!? Surely they wouldn't run race fuel without tuning for it? That'd just be dumb.
Oh and as for tasty fuel, Sunoco's just wrong, mate!!! Everyone with any taste knows that C16 is where the flava's at!
