When refiners cut ZDDP (zinc) levels due to EPA regs to compensate they increased molybdenum (moly) levels. The added moly is what is bad for wet clutches.
No, they dont. Very few do. Some use higher quality base oils instead.
And, the moly isnt (in and of itself) whats bad for clutches, if it were, we would all have issues, as every oil has moly in it as part of an additive package.
BTW, if moly were bad, ZDDP works just as good or better, for a LOT less money to protect metal by making stuff slippery, so why doesnt high levels of that additive cause problems? Because there isnt enough of it there to cause an issue.
Friction modifiers are whats bad....and they too are part of an additive package, but the way you know its bad is that little "energy conserving" warning on the label.
If it doesnt have it, its fine for use in a wet clutch application. Period.
