According to LiquiMoly this product seems to booster concentration of moly in engine oil. I have never used it and would like to see what it will do to my engine. Would it reduce wear on frequent short trip? How much moly ppm increase it would bring in 5 Qt. engine oil? Thanks.
There’s already some good advice in this thread, and I’ll throw this in for you to digest: in the last thread I remember perusing on this, the OP was again thinking lots of extra moly would prevent wear.
I think that’s a largely spurious assumption; one of the UOAs in that thread showed similar mileage to the universal averages and a moly content that was literally 3x the universal average…. Yet “wear” metals as a whole were literally exactly in line with universal averages.
To me, to the extent that a UOA can assess wear (TL;DR: it can’t) this shows moly does not positively or negatively impact results. Moly is a softer metal, and I think it acts more as a “shock absorber” or sound dampener. Sure, there are some papers showing moly “reduces friction” which is likely true, but if there’s no measureable benefit, is it?
IMHO, if you think your application requires “boosting”, save your money and buy a better oil rather than dumping random additives in.
But the good news is, your engine is far more positively impacted by the fact that you 1. Use an oil that meets the required specs, and 2. Change it at the recommended frequency, than it ever will be by dumping additional additives in with the oil. You can take that to the bank.
