I would agree, Palangi.

I don't know what car OP is trying to acquire oil for. If it's one of the early '80's diesels, I'd be looking for something far more robust (ability to suspend soot) than a CF oil.

OP: Why not continue use of the Rotella syn you're already using or step up to the M1 Turbodiesel Truck easily found at Wall'smart for $23/gallon
