550 fan and 91 oct

[Snoplug]

I put 91 in my wifes sled today after I filled mine. When I got to the trail the warning light came on just as we started: Temp, Oil and (!). I am hoping it is just the fuel, it ran great a week ago on 87. Any ideas? Thanks

unlikely fuel if yours is still running extra octane is a good friend

You should be fine on 91. We have a 550 at 80hp (+20 from stock) and run it on 91
