I believe there are alot of good additives out there not only Auto-Rx. They all serve their purpose. Do you call Nulon, Amsoil and other Solvent flushes snake oil ? They do their job but not as safely as Auto-RX does. Liqui Moly MOS2 is another good additive. Yes there is enough good literature to suggest that Teflon based additives either do not work, or not as effective in the engine, in other areas possibly they work.
If Opti Lube was a site sponsor, would the site managers be coming to their rescue ? Yes i agree some people were bagging out Auto-Rx when it is a fantastic product.
I agree with Molakule, but their claim of 40% could be true, you would hope any oil is reducing it by that much. But what is it compared against, how much wear exactly ??? This is typical marketing confusion....
