Question of Moly

[Ken42]

I have noticed while searching thru this board that some oil's such as Amsoil, Valvoline and others contain no Moly but then Pennzoil, Schaeffers contains alot along with RedLine and Mobil what gives. Why some have it and others don't? I understand that it is for wear but what do the oils that don't have Moly use instead?

Moly is good but isn't absolutely critical to make a good oil, as there are other antiwear additives which work too, such as boron. Many oils use other types of antiwear that don't show up on a typical oil analysis sheet too.
