DO a search on this subject. You will find I have ran most-everything. If it was more convenient for me accessing Maxima, thats all I would run. Although pricey, It's the best oil available IMO.

 

I use TORCO RACING OIL http://www.torcoracingoils.com/produ...tsGroupIDPK=58

 

Im running Motul full Synthetic. From dealer Yamamlube is garbage. low grade oil. Yamaha is thinking about getting rid of the line or new start.

 

Yamalube garbage? I seriously doubt that. This debate will rage forever. If you got the bucks, go with Maxima full synthetic. Awesome oil. I'm sure amsoil is great too. I'm using Yamalube semi-synthetic with no problems. Garbage? Naw!!!

 

I used to use yamalube..then by accident i used a single quart of the semi synthetic..blew my clucth out. i now use Honda 10/50..Thats some good oil...nice and thick too. also i noticed that even after one ride with the yamalube..the oil would be be black!!

RUn the honda oil you wont be dissapointed..

 

I use Amsoil in everything I own. Fabulous stuff.

For anyone that says one oil is better than another, How can you tell? I know the ones, like myself, that tried semi-syn. and lost a clutch I understand, but how about everyone else?

 

I have run Amsoil in my 2 Polaris, LT250R (Two Stroke Oil as well), 400EX, Raptor, 2 426's and my 929. We run it in a lot of vehicles. Very impressed with the results.

On my 929, I changed out the break in oil, and went to the Amsoil and the motor was noticably quieter.

I have yet to have a motor failure using Amsoil. So far, it is the one I trust the most.
