The 911 guys love to use it and that is where most of my research on it was done. It may reduce wear and help preserve the engine but you will ever escape the fact that metal is rubbing on metal, it simply will wear out over time.

I politely disagree. Case in point, molybdenum as a kind of unrelated example (not usually in most oils
AFAIK) actually bonds with metal on a molecular level and sacrifices itself to prevent metal on metal contact or wear. Zddp does the same thing, but is only useful in high impact situations, like cam lobes and lifter surfaces.
Molybdenum alone can eliminate metal wear to the point where its undetectable. There is a reason for almost everything they or we add to oil. Almost everything, some of it I do agree is BS.
