OPERATION
Fuel
The fuel used in the Polaris engine is as important to engine life and performance
as the lubricant used.
Most Polaris engines are designed to run on 87 octane non oxygenated or 89 oc-
tane oxygenated pump gasoline. There is a great deal of variability in the quality
of the 87 octane gasoline available across the country. We encourage the use of
premium fuel when possible. NOTE: XCR models require premium gasoline.
Consult your Owner’s Manual Supplement for specific minimum octane require-
ments.
Premium Fuel Switch
Some Polaris snowmobiles are
equipped with a key function that will
adjust the timing on the machine as
you change fuels.
Most high performance machines re-
quire the use of premium fuels. When
premium fuel is not available, there is a
risk of engine damage when other
fuels are substituted.
When using fuels with a pump posted
octane rating of 91 or higher, turn the
key switch to “ON/PREM”. When the
engine is started a yellow “Premium
Fuel” light illuminates on the instru-
ment panel. When the key is in this
position, the fuel
must be a minimum
of 91 octane.
If you are uncertain about the quality or octane rating of the fuel you are using, turn
your key switch to “ON/REG”. The “Premium fuel” light will go out. This setting will
adjust the timing of your engine to run on fuels with 87 octane or higher. Polaris
does not recommend using fuel with lower than 87 octane.
Running your machine on “ON/REG” will protect your engine from damage caused
by low octane fuels. It is very important to the life of your engine that you are aware
of and use this feature.
