For all we know, they DO use it, or at least something like it, as part of their factory fill.. I have never seen the stuff that goes into the engine at the factory. I do know that I've seen UOAs on at least 1 or 2 factory fill oils that look like it's got some sort of extra mojo in it compared to over-the-counter stuff.
Not saying they do, of course, but who is to say they don't?
