[img]i/expressions/face-icon-small-blush.gif[/img]IVE HEARD NOT TO USE IT,AND SOME PEOPLE SAY ITS OK,I USE MOBLE 1 FULLY SYN. SOUNDS LIKE A DUMB QUESTION,BUT I HEARD ITS NOT GOOD IN THE ROTAX?

 

I use valvoline dura blend 10w-40. Havent had any problems with it and been running it since 2001. The valvoline is a synthetic blend but it is not a full synthetic oil. I havent never heard if all synthetic oil will hurt the motor. Try doing a search on this matter and see what turns up. [img]i/expressions/face-icon-small-smile.gif[/img] Lance

 

It's okay as long as it is designed for wet clutches. The factory oil is a fully synthetic oil.
