Choosing the right engine oil After checking some forums I decided to buy 15W/40 SL Superfleet oil for my XV750, but when I got home I decided to do some more reading before actually putting the oil in, and found some conflicting information regarding non-motorcycle engine oils.

Some people say it is a scam, some say to only use motorcycle specific oil.

Clymer's says to use 20W/40 SE-SF. Will 15W/40 SL work despite the wet clutch and not being motorcycle specific? Thanks, I'd rather be safe than sorry on this.
