Some synthetics and energy conserving motor oil say they contain "friction modifiers". Can anyone tell me exactly what they are?
I've heard that they shouldn't be used in motorcycles with wet clutches, but some riders who ride bikes with wet clutches use synthetics without experiencing clutch slippage.
Is molybdenum disulfide one of the friction modifiers?
