Al said, there's more to an oil than the sum of its parts which show up in a typical UOA/VOA. That's why some additives backfire. I'm thinking of one guy who showed up here after adding "Tufoil" to his oil. His analysis didn't look so hot.

Depending on the other additives, there's an optimal amount of moly/boron/zinc/phosphorous/calcium, etc ... and the
type/fprm of each is critical.
Yes, at least some molydisulphide would end up getting filtered out.
