Lubrication Recommendations

Engine Oil

Always check and change the engine oil at the intervals outlined in the
Periodic Maintenance Chart beginning on page 73. Always change the
oil filter whenever changing oil.

Premium 4 Synthetic Oil

Polaris Premium 4 All Season Synthetic engine oil has been specially
formulated for use in Polaris 4-cycle engines. It's a fully synthetic,
high performance, multi-viscosity oil designed to provide the ultimate
in lubrication performance and protection. See page 119 for the part
numbers of Polaris products.
Premium 4 possesses unsurpassed film strength over the widest
possible temperature range. It resists viscosity and frictional
breakdown in ambient temperatures from -40° F. to 120° F. Its
exceptional frictional properties result in more efficient operation, more
power output and lower fuel consumption.
Although Polaris Premium 4 is the only oil recommended for use in
this engine, use of any API certified "SH" oil is allowable as long as
it's 0W-40. Oil may need to be changed more frequently if Polaris
Premium 4 is not used. Follow the manufacturer's recommendations
for ambient temperature operation.
CAUTION
Mixing brands or using a non-recommended oil may cause
serious engine damage. We recommend the use of Polaris
Premium 4 All Season synthetic oil or API certified "SH" oil,
0W-40. Never substitute or mix oil brands. Use only 0W-40.
