What happened that your engine "suffered terribly"? Lots of folks use MoS2 without issue. I've never heard of any issues stemming from running it per the instructions/dose rate.A bit of it is O.K. in splash lubed ODPE. Like my Chonda powered Generac.
I will recommend against LM MoS2 in pressure lubed engine with full flow filtration.
I found a few drops make a good penetrating oil when taking my Gas Oven ignitor bracket apart
Fell for the heavy hype on here a decade ago, and my Honda Fit sport engine suffered terribly.
This made me quite unhappy for being the gullible fool - and really knowing better
Correlation, causation, coincidence? Can't say.
