It looks like OCi 5 through 8 are Amsoil, me personally?
I dont see anything wrong with the Moly, its commonly used in motor oil, in fact, in oil its almost as common as the oil itself, same goes for Boron another common additive...
Moly? ... me personally I would not even give it a thought, however you are thinking about it then the only way is to knowingly purchase 100% moly free oil and run it for more then a few OCIs ...
