which gas?

[mxz500rider]

Alright guys, got a '11 shift 600 cfi. Gettin ready to head to ironwood on Sat. Noticed the wires for the oxygenated fuel is un-plugged. If I leave it the way it is, what is the highest octane fuel I can run? Not really worried bout the extra cents at the pump. Sled is completely stock. Ride only trails. Thanks.

Get premium every time, no ethanol if possible.

I'm headed up with my 600 Shift as well. Staying outside of Hurley so I'll probably see you on the trails. I'd plug it in and run 91 ethanol free if possible. At least that's what I'm doing. They have 91 e-free in Mercer.
