Oil Recommendations
The only source of engine lubrication for your engine comes from
lubrication added to the fuel. We highly recommend the use of only
Polaris products. We’re continuously testing lubricants and provide the
highest performance products available for your snowmobile’s engine.
We recommend the use of Polaris 2-Cycle Racing Oil for your
snowmobile. See page 99 for the part numbers of Polaris products.
Never mix brands of oil. Serious chemical reactions can cause system
blockage, resulting in serious engine damage. They may also be
incompatible and the result could be sludge formation, filter blockage,
and reduced cold weather flow rates. All Polaris oils are compatible
with each other.
Fuel Recommendations
110 Octane
The fuel used in your Polaris engine is as important to engine life and
performance as the lubricant used. Always use 110 octane fuel for the
440 IQ snowmobile.
CAUTION
Using fuels with a l ower 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.
