I hate to be "that guy", but what data to do you have to prove that? I don't mean generically speaking, ie lubing up your kid's pinewood derby car or something, but in this specific application.............M1 formulated a very good oil, seems odd to me to dump some other stuff in with it without a lot of testing.....robert
For my comment about deposits risk with too much moly, specifically in 0w-20 oils, there is some tech evidence:

For my comment about friction and anti-wear functions of moly, notice Mazda Genuine Motor Oil 0w-20 synthetic, made by Idemitsu, uses 600 ppm moly, a high amount, and gets a waiver of TEOST GF-5 requirements, and Mazda claims right on the bottle
"Include high levels moly which reduces wear, especially at low temperatures when the anti-wear agents are inactive." This corroborates what MolaKule (bitoger) has said about moly's function, being primarily a
FM at lower concentrations seen in a typical motor oil, and has
AW properties in heavier concentrations, phasing in past around 200 ppm approximately in some old SAE tech papers I've read and am too lazy right now to list. I'm reaching for a beer now...
