I have some Yamalube 20 w 40 sitting around and need to change my oil..Has anybody used this in their DS ?
Will Car oil work 10 w 40 got some of that too!

 

Yamalube is some of the best stuff there is for quads. Use it, it works great. Don't use car oil if it has energy conserving minerals in it because this is bad for your clutch!! It will say on the back of the container if it has this. I wouldn't use car oil anyway just for piece of mind. But Castrol GTX oil is very good too if you want to stick with car oil, also stay away from synthetic oil unless it is for wet clutch systems........ I still wouldn't use it though.

 

Yamalube is good stuff. I would stick with oil designed for offroad use. They are formulated for a higher rpm.
