Snowtech was wrong. The 650 Patriot, is like other recent engines from Polaris. It has 2 fuel type settings, based on what fuel you are using, and maximum performance is obtained with 91 octane or higher Non-ethanol fuel in the 91 NON-ETHANOL fuel type setting.
It will run fine on 87 octane upto 10% ethanol, in the NON-PREMIUM / ETHANOL fuel type setting
OK thanks, I wonder why where they got that info.
