Oh no, not another one of these threads, they are as bad as the oil threads. It doesn't matter, any name brand gas will be just fine. Polaris suggests premium but unless you have done any major mods then mid grade will work just fine. I also get the same gas mileage out of ethanol blended and non-ethanol, go figure.
