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.
NOTE: Some Polaris snowmobiles require premium gasoline.
Premium Fuel Switch
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.
Most high performance machines
require the use of premium fuels.
Substituting other fuels may cause
engine damage.
Premium Fuel Setting
Regular Fuel Setting
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.
