Standard filters (Im in Europe so cant give you names), filter particles over 40 microns. That is tens of times larger than 1,5 microns. Imperfections (scratches) less than a micron are minor at best.
A dry lube by definition cannot be abrasive. Oil cannot be abrasive.
The real breakthrough Lm supposedly made is keeping moly floating around(as part of the oil). It goes all the way back to 1940's, maybe earlier. How much better are todays oils and dispersant packages.
While the chemistry is over my head, I fail to see any issue using "standard grade" moly powder, other than the fabled clumping at the bottom of the pan.
This point also seems incorrect. Oil is not being poured it is pumped. So the oil pump would keep it in suspension. Moly is attracted to surfaces with increased temperature and friction. It is also EP additive.
So sitting it should remain inert and even if it does nothing, it certainly cant clog anything at 3gr per 5l of oil.
Moreover it would not stick to the first point of friction, as we know, it layers itself under the above conditions over time.
A neighbor of mine swears by the stuff, I guess I talk to him a lot
Hopefully someone knowledgeable would shine some light
