MAINTENANCE AND LUBRICATION
Engine Oil
Always check and change the engine oil at the intervals outlined in the
Periodic Maintenance Chart beginning on page 58. 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. Polaris recommends the
use of Premium 4 in this engine, but 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.
See page 100 for the part numbers of Polaris products.
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.
Oil Check

1. Position the machine on a level surface.
2. Start the engine and let it idle for 20-30 seconds. Stop the engine.
3. Remove the dipstick and wipe it dry with a clean cloth.

the safe operating range (2). Do not overfill.
