MAINTENANCE AND LUBRICATION
Engine Oil
Premium 4 Synthetic Lubricant
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. NOTE: See page 100 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.
WARNING
Vehicle operation with insufficient, deteriorated, or contaminated
engine oil will cause accelerated wear and may result in engine
seizure, accident, and injury. Always perform the maintenance
procedures as outlined in the Periodic Maintenance Schedule.
