Can't answer your question any better. And if you were expecting a simple answer to this question, you haven't spent much time on these forums. There are hundreds of threads on this topic. This one at least gives some technical background to those that might have the interest.

Agreed. And though I don't agree with JFP on some of the technical points, such as DPN depletion rates, I do bow to his vastly superior apparent resource base and knowledge of this particular engine.

To the point where I'm going to either buy castrol or buy another oil and start doing UOAs, but I'll skip using my 0w40 at this stage.

Yes I'll skip the mobil-1 for the castrol as well--But it seems the discussion got away from the question-try to engender a little humor and get scolded for it--I hope owning a Porsche doesn't "deplete" my sense of humor--

It's a shame that 50% of communication is non-verbal. We couldn't see the wink of your eye...
