Oil Recommendations
Polaris recommends the use of Polaris PS-4 PLUS Performance Syn-
thetic 2W-50 4-cycle oil or a similar oil for this engine. Oil may need to
be changed more frequently if Polaris oil is not used. Always use 2W-50
oil. Follow the manufacturer's recommendations for ambient tempera-
ture operation. See page 124 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 Level
Access the oil dipstick and fill tube
from the left side of the vehicle.
1. Position the vehicle on a level
surface.
2. Lift the lever lock to remove
the dipstick. Wipe it dry with a
clean cloth.
3. Reinstall the dipstick com-
pletely, but do not lock it. The
dipstick must be inserted com-
pletely to keep the angle and
depth of the stick consistent.
4. 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 dip-
stick.
5. After reinstalling the dipstick,
seat the lever lock.
