Fuel Recommendation

NOTICE
Prolonged exposure to petroleum based products may damage paint. Always protect painted surfaces when handling fuel.

North American Fuel

For peak performance, POLARIS recommends the use of fresh quality, non-oxygenated 91 octane level fuel or above. Although 87 octane fuel is usable, some engine performance will be lost and fuel economy will decrease. NEVER use unleaded fuels with an ethanol rating of E15 or E85 as severe engine damage may occur. Use the indicated fuel setting with your gauge when choosing fuel.

IMPORTANT

NEVER use fuel containing more than 10 percent ethanol, including E85 or 88 E15 fuel, in your snowmobile.
