OPERATION
Fuel
Your Polaris engine is designed to run on 87 octane non-oxygen-
ated or 89 octane oxygenated pump gasoline. There's a great deal
of variability in the quality of the 87 octane gasoline available
across the country, so we encourage the use of premium fuel when
possible. Always use the premium fuel switch when using premium
fuel .
NOTE: Some engines require premium fuel. See your Owner’s Man-
ual Supplement.
Premium Fuel Switch
If your Polaris snowmobile is equipped
with a key function to adjust the timing
on the machine as you change fuels, it's
very important to the life of your
engine that you use this feature.
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 instrument
panel. When the key is in this position,
the fuel must be a minimum of 91
octane. Return the key switch to the
ON/REG position when not using pre-
mium fuel.
If you're uncertain about the quality or
octane rating of the fuel you use, 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 help protect your engine from damage caused
by low octane fuels.
CAUTION
Using fuels with a lower than recommended octane or operating with
obstructed fuel systems will result in serious and costly engine damage.
Always use the recommended fuels for your machine.
