Watched a demo last night on Schaeffer 15w-40 w/ moly. It would plate up on the roller when others would not, just like a moly grease. My question is, is having a moly that plates up a desirable trait to have on the inside of an internal combustion engine? I kinda figure if there's no oil long enough the the moly to plate up, you've got other problems.... I also know that Molybdenum disulfide is a type of clay..... Again, doesn't bother me in a grease, but in an engine?
Opinions?
