No worries. Chances are that it doesn't matter if it's trinuclear, mononuclear, or dinuclear if you have a high concentration of Mo.
I think basically, say, 75 ppm Mo via trinuclear moly does the same job in wear protection, antioxidation, and friction reduction as 300 ppm Mo via dinuclear moly, but at one point (after a certain moly level) the effects saturate for both. Therefore, if you don't have trinuclear moly but have dinuclear or mononuclear moly, all you have to do is to add more moly, and you will see the same end result.
The important thing is that the organic moly should contain both Mo and S; otherwise, it won't result in the coating of the metal parts with a MoS_2 film and you won't see friction-reduction and antiwear benefits.
Interesting that there are so many aftermarket organic-moly additives out there (Lubeguard, Torco, etc.). I didn't know.
