i had massive slack in my chain.... and a missing bolt, and that was making my engine rattle.
and yes, lubromoly moly treatment is the ****!
they sell just the moly part that you can add to any oil as an extreme friction reducer.
for the M60, run 0W40 full synthetic with one bottle of Valvoline Synpower oil treatment and one bottle of LM-MoS2
if you live in death valley or somewhere that when you cold start the engine temp meter is always above blue, then go to 50wt
