Fuel Recommendation

North American Fuel

For peak performance, POLARIS recommends the use of 91 octane fuel or higher, with no ethanol. Although 87 octane fuel is usable, some engine performance will be lost and fuel economy will decrease. Do not use lower than 87 octane fuel.

IMPORTANT

Do not use fuel containing more than 10% ethanol. Never use E85 or 88 E15 fuel in your snowmobile.

NOTICE

Operating with obstructed fuel systems will result in serious engine damage. Perform maintenance as recommended. Prolonged exposure to petroleum based products may damage paint. Always protect painted surfaces when handling fuel.

International Fuel

For peak performance, POLARIS recommends the use of 95 octane E10 gasoline or higher octane. If lower octane is used, some engine performance will be lost and fuel economy will decrease. Do not use gasoline with higher ethanol rating than E10.
