A word on Teflon additives.
First: your oil filter will remove all traces of it in a few minutes of engine operation, long before it has any chance (if it were possible) to bond to metal. Teflon does not disperse in oil, it remains in suspension to filtered out.
Second: DuPont, the inventor of Teflon spent literally millions of dollars trying to get Teflon coatings to stick to cookware. We all know how well that worked. There is no way, at least in the realm of known science, that pouring a Teflon laced oil additive in to your engine will cause the Teflon to miraculously bond to metal surfaces....absurd.
It is a futile battle trying to convince people this stuff does nothing for their engine. It's like the control group who receives sugar pills, and feels so much better.
