MAINTENANCE
Engine Intake Restrictor Plate
Some RANGER 800 models are equipped with an intake restrictor plate
in order to meet vehicle class regulations. This plate MUST NOT be
removed for any reason. Removal of the intake restrictor plate will void
the warranty on the vehicle.
Engine Oil
Always check and change the engine oil at the intervals outlined in the
Periodic Maintenance Chart beginning on page 62. Always change the
oil filter whenever changing oil.
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 Chart.
Oil Recommendations
Polaris recommends the use of Polaris PS-4 PLUS Performance Syn-
thetic 2W-50 4-cycle oil or a similar oil. See page 116 for the part num-
bers of Polaris products.
NOTICE: Mixing brands or using a non-recommended oil may cause serious
engine damage. Always use the recommended oil. Never substitute
or mix oil brands.
