<sigh> ... if the issue you're going for is the dry start thing, then all the comparisons I've read between Brad Penn and Joe Gibbs give the
slight edge to Brad Penn on that point. For example, this is fairly typical, from
Circle Track:
Pennsylvania crude oil, which is the base stock for Brad Penn Racing Oils, has a naturally occurring wetting agent that enables the oil to stay put and resist slinging for an extended period of time. Engine Lubricants - Solving The Flat-Tappet Puzzle - Circle Track Magazine Now, is all of the stuff that I read true? Who knows. Basically, if you just do what Chas tells you to do you'll be fine.
