Here are some previous posts about moly from MolaKule:
1. Indeed, this is an old report, comes up occasionlly, and has been discussed at least three times before. To compare soluble moly to the snake oil additives is ludicrous.
The fact is, a specific and early compound of moly, a class of molybdenum phosphordithioates, was "suspected" as being the cause of some corrosion. There was never a proven correlation.
Interestingly, those same molybdenum phosphordithioates have been used successfully in hydraulic oils without any problems or suspected corrosion problems.
Today's modern molybdenum dithiocarbamates, have never been the center of controversy or suspected corrosion.
In addition, the comment about the copper deactivator is also out of date and no longer correct.

2. Please read this post and look at the various additives for each application or spectrum of applications:

There are many chemistries for friction modification, anti-wear, and Exreme pressure.
Moly is but one of them. In low concentrations, it acts as another friction (reduction) modification additive, in medium concentrations it acts as a friction modifier and anti-wear, at high concentrations it acts as mainly as an EP agent. There is nothing majic about it, it works, just like ZDDP.

3. NOTE THE QUOTE BELOW IS NOW ALMOST FIVE YEARS OLD:
Tests have shown that engine oils can tolerate up to 750-800 ppm of moly dithiocarbamate before serious additive interactions takes place. So thats about 0.08% weight/weight.
And much depends on the OTHER additives present.
I would highly recommend you send in your mix for a VOA to Terry dyson before you run this stuff and then do UOA's every 1,000 miles.
