Just a little applied logic can tell us a lot, for example, does anyone believe that if such compounds held the magical properties suggested the oil manufacturers wouldn't be falling over themselves to add them to their own oils?
It would be a race to market, a whole new generation of super hype from numerous oil manufacturers would fill roadside signs from end to end of the country.
They don't for a very simple reason, they can't, because most so called wonder additives work on the psyche rather than the engine. They can also cause the actual lubricant itself to break down, I learned many years ago that an engine needs only one lubricant, the best quality oil you can identify and afford.
There may be benefits for those using cheap basic oils which lack any real lubrication qualities anyway, but I doubt a single quality lube manufacturer missed this wonderful opportunity to increase profits! For goodness sake, just look at the lengths some oil companies go to hype their products now, half the "synthetic oils" available are over 90% mineral, they wouldn't miss an opportunity like this!
