Engine Oil Recommendations
Always check and change the engine oil at the intervals outlined in the Periodic Maintenance
Chart beginning on page 87. Polaris recommends the use of Polaris PS-4 PLUS Performance
Synthetic 2W-50 4-cycle oil or a similar oil designed for use in 4-stroke manual clutch ATV
and motorcycle applications. Do not use Polaris PS-4 Performance Synthetic 10W-40 Oil.
Always use 2W-50. See page 172 for the part numbers 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.
If the ATV is used year-round, check the oil level frequently. A rising oil level could indicate
the accumulation of contaminates such as water or excess fuel in the bottom of the crank-
case. Water in the bottom of the crankcase can lead to engine damage and must be drained.
Change the oil immediately if the oil level rises.
