4 Cycle Premium 4 Synthetic Lubricant
Polaris Premium 4 All Season Synthetic engine oil has been specially
formulated for use in Polaris 4 cycle engines. It is a fully synthetic,
high performance, multi-viscosity oil designed to provide the ultimate
in lubrication performance and protection.
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. Oil may
need to be changed more frequently if Polaris Premium 4 is not used.
You will also need to follow the manufacturers recommendations for
ambient temperature operation.
Fuel Filter
Your Polaris RANGER is equipped with an in-line fuel filter that
should be replaced by your dealer after every 100 hours of operation.
Do not attempt to clean these filters.
