It is well proven that HDEOs work well in motorcycles, so they likely have similar base stocks and additive packs. How do motorcycle oils as a group differ compared to HDEOs?
Some HDEOs have moly in them, so they may have too much for wet clutches. I assume since motorcycles run at higher RPMs, motorcycle oils may have more antifoam additives.
