5w-30w has additives in it to make energy conserving. basicly makes slipperier. good for cars, not so good for motorcycles with wet clutches. if you want to run mobile 1, try 15w-50w. i don't think its energy conserving. look on the back of the bottle there is a circle theat with the ratings stamped around it, and inside it will say if it is energy conserving, if not it wont say anything.
