Yeah, I'll get back to this. Someone has tracked me down on a Porsche forum to copy and paste that there, as well. Registered just to ask me that publicly, and the only post made since then. Been out of town and away from internet access but am now replying to it. So I thought I'd check here. Cut and paste, right down to "page 97" of a 7 page PDF.
Have to roll my eyes at the "paper." Long on assertions, way short on data. The only citation they make is about how it is being marketed, and that reference contains data that refutes their claims. Nothing resembling a DoE. Picked 5% and ran with it. That seems like kind if a whole heapin' lot of any kind if EP additive to me, anyway. No explanation of how they did their testing for anything beyond the 4-ball test.
Lots of speculation, "may cause" types of stuff. Right.
OH and hte health thing. It is received in suspension. Small particles are a concern when airborn, and the CDC does call out a question about migration from lungs to other parts of the body. In the environment where they are made. At the user level, given that it is in suspension at the tier 2 level to go into a tier 1 product, it won't really be airborn.
The later linked military one is interesting, given that MIllers has used a Sequence-6 test to show fuel economy improvements from a lab in San Antonio. Hits 6 speed load points meant to simulate a drive cycle. And the results were affirmative (i.e. was a gain).
FWIW, Aston Martin switched to MIllers with NT for their factory fill gear oil in January of this year. Previously specified a 40,000 mile service interval, but now call it a lifetime fill. We have tons and tons of similar feedback from the gear oil, in F1 (quite confidential, unfortunately), WRC (Jipocar - sponsored), IndyCar (Bryan Herta AUtosports last year - tech partnership, NOT a sponsorship). Have a NASCAR supplier (independent) and a team (sponsored by a competitor) testing it right now, but they have not shared any results with us. We have a motorcycle team sponsored by a competitor who hadn't been able to finish a race until they switched to Millers, and as much as I'd love to elaborate, any more detail may reveal who it is, which I cannot do.
Blah, blah, blah. Anyway, will try to get back to more. Have to give a more formal response given we were a site sponsor when I first posted the prior one.
