OK Yamaha has stop making 20w-40 oil now. I alway thought that was strange weight for a oil but that is what they said to use. I can not get a straight answer from one dealer to the next on what Yamaha says to us now. Is anyone using 20w 50 out there and for how long or is 10W40 the way to go what to do, what to do? sorry 2nd gen
