Hi Mike, glad to hear from another person involved in Tribology and engine testing. I have used Savant in the past as one of many contracted lab testing facilities when developing lubricants.
It will be interesting to see your results of Everglide and the number of engine parameters monitored.
In my view the best set of test results as to wear, albeit expensive and time consuming, is the before and after physical measurements of component parts.
In terms of the effects of friction modification additives, a well monitored operational engine is a good method to determine their effects.
I question any multi-nanoparticle OTC additive until its efficacy has been thoroughly proven by proper and comprehensive testing. On-site Lab tests and simulations only provide a partial answer.
Apparently the Everglide OTC additive contains a Group V base oil, most likely a trimethyl-propionate ester (TMP) and a mix of moly and graphene nano-particles. The question is does this mix provide a synergistic combination, or does the Group V base oil provide provide the major alleged reduction in friction?
Most modern oils today already contain a MoDTC component as well as an ester. As much as the topic of Graphene has captured technical paper main titles, the main application of graphene's seems to be in integrated circuits as of today.
As to volatility, the lower the volatility the less ash and other deposits that will accumulate on valve surfaces, spark plug insulators, and CATs, and is an important specification.
In my view, ashless detergents, dispersants, anti-wear additives, and friction modifiers will do much to reduce deposits until we get to formulations with 1% volatility.
