OPERATION
Fuel
The fuel used in your Polaris engine is as important to engine life and
performance as the lubricant used.
Your Polaris engine is designed to run on 87 octane non-oxygenated 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 Polaris snowmobiles require premium gasoline.
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
premium 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.
