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

INTERNATIONAL FUEL
For peak performance, POLARIS recommend 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.

FUEL SYSTEM DEICERS
If you use non-ethanol fuel (sometimes labeled “non-
oxygenated”), POLARIS recommends the regular use of
isopropyl-based fuel system deicer. Add 1-2 ounces per
gallon (8-16 ml per liter) of gasoline to prevent damage
resulting from fuel system icing. Never use deicers or
additives containing methanol. POLARIS recommends
the use of Carbon Clean.
IMPORTANT
If you use fuel with up to 10% ethanol (sometimes
labeled “oxygenated”) do not add deicers or additives
that contain any form of alcohol. Adding deicer to
oxygenated fuels could result in severe engine
damage.
