friend fixin to service his new(to him) prairie an was wanting suggestions on oil type an any other thoughts on maintenance needed!! not sure of year model,it is a v-twin an 4x4,thanks for any replys!

Not sure what weight the owners manual recommends but Shell Rotella 15W40 is about $13.00 a Gallon at Wallyworld. It's JASO MA rated. I use it in all my motorcycles and ATV's.

rotella is good oil,...just making sure it dont need wet clutch oil or nuttun exotic...thanks

No worries with Rotella oil as it is Jaso MA. Most issues were with Energy conserving automotive oils like 5W30.

Just curious, but why would a cvt atv require motorcycle rated oil when it has no wet clutch to get messed up by moly content in Starburst type auto oils?

Now, Rotella is a good choice anyway. They also have a T6 5w40 which is rated for MC's and I run it in my Concours.

I've used Automobile 5w30 Mobil 1 in my atv in the winter with no ill effects.

it wouldnt less it had a wet clutch,..ant asked fer wet clutch oil,..asked if it needed it,...an fer best oil for this wheeler,..read first post!

Yes.......good point but you could argue that energy conserving oils and car oils in general contain less ZDDP. That's a whole seperate debate. If you use Rotella your pretty much covered for cheap money. Most likely you could use anything if you change it often enough.
