Thanks for the data subdriver.
However... (sticking head on chopping block)
what exactly does the data tell us as far as dissolved particles, extended oil change sequences and engine wear are concerned? I don't think it really addresses the issues I've brought up. Were engine tolerances measured before and after the study? Why do the levels of contaminants rise quickly after an oil change then stabilize until it's changed again? Does wear stop? How? Why? Not to mention, what additives keep abrasive particles from wearing out metal to metal surfaces and how do they do that?
(sorry, I'm not trying to be difficult, and hopefully I'm not deriding anyone, I'm a technically minded person and my bs meter is pegged, that's all).
