Most 10w30 oils (like Pennzoil) contain friction modifiers, which may cause clutch slippage.

A blanket statement like "10w30 contains friction modifiers" is false. Some may, but others may not.

Many have had good luck with ATF TYPE F in their trannys. its cheap enough so it can be changed after every ride. I use atf type f and sometimes use castrol gtx 10/40 and sometime use motul 2 stroke tranny oil...whatever I have on hand.
