It's easy to take a cynical attitude on this, I admit.

But - just suppose whatever's in Marvel or Lucas really does enhance oil. Neither is terribly expensive, certainly no more expensive on an industrial level than the additives they already use. (I know for a fact that the metalloid stuff is extremely costly and often difficult to handle in manufacturing processes.) If those additives really did something useful, they're either in there, or would be in there, or the oil sellers would be purposely avoiding their use. That last makes no sense at all unless you're going to postulate some kind of back-room deal between oil makers and engine sellers. That's easy to dismiss as nonsense, as manufacturers are intent on extending oil change intervals as far as possible and would happily pay a few percent more for oil that keeps their warrantied engines from wearing out prematurely.

Nah. The additives, barring perhaps specific ZDDP boosters, are hokum and (snicker) snake oil.
