MAINTENANCE

Engine Oil

Always check and change the engine oil at the intervals outlined in the Periodic Maintenance
Chart beginning on page 57. 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 5W-50 4-Cycle Oil or a similar oil. See
page 90 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.
Oil Check
The oil tank is located under the seat.
1. Position the vehicle on a level surface. Place the trans-
mission in PARK.
2. Remove the seat. See page 24.
3. Lift the lever lock to remove the dipstick. Wipe it dry
with a clean cloth.
4. Reinstall the dipstick completely, but do not lock it. The
dipstick must be screwed completely in to keep the angle
and depth of the stick consistent.
5. Remove the dipstick and check the oil level. Maintain
the oil level in the safe range. Do not overfill.
Tip: Due to the dipstick entry angle into the crankcase, the oil level
will read higher on the bottom side of the dipstick. Always read
the level on the upper surface of the dipstick.
6. After reinstalling the dipstick, be sure to seat the lever
lock.
7. Reinstall the seat.
