The way we knit-pick oils on this forum, seeking the best.....don't we all want the product that give the absolute lowest possible wear?
i think we want the product that is the most cost effective solution. if we all wanted the best oil, period, there is RLI out there at 10 bucks a quart, or some other boutique oils at even more. M1 @ a little under 7 bucks is a cost effective way of getting 10k with a good synthetic. as i have said before here, the fact it also passes GM4718M makes me believe this is all bunk.
but i have been wrong before....
