MAINTENANCE

Engine Oil

Always check and change the engine oil at the intervals outlined in the 
Periodic Maintenance Table beginning on page 80. Always change the 
oil filter whenever changing oil. See page 133 for the part numbers of 
POLARIS products.

Oil Recommendations

POLARIS recommends the use of Performance Synthetic 4-Stroke oil 
(PS-4 or PS-4 Plus) for this engine. PS-4 has been specially formulated 
for use in POLARIS 4-cycle snowmobile engines. It's a fully synthetic, 
high performance, multi-viscosity oil designed to provide the ultimate in 
lubrication performance and protection.

Oil may need to be changed more frequently if POLARIS PS-4 oil is not 
used. Follow the manufacturer's recommendations for ambient tempera-
ture operation.

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.

MAINTENANCE

Engine Oil

Oil Level Check

Note: Read the entire oil check procedure before checking the oil level.

The oil level will rise as engine temperature increases. The oil level will 
be lower when the engine is cold. To obtain a proper oil level reading, 
the snowmobile must be on a level surface, and the engine coolant tem-
perature must be between 145° and 160° F. (63°-71° C).

Always check the oil level before operating a snowmobile that has 
tipped over.

NOTICE: Severe engine damage may occur if procedures for checking the oil 

level are not followed precisely. Always check the oil with the 
snowmobile positioned on a level surface. Always check the oil level 
when the coolant temperature is within the specified range.

MAINTENANCE

Engine Oil

Oil Level Check

The oil level in the oil bottle may drain below the level of the dipstick if 
the engine has not run for more than a week. If you're not sure if there is 
oil in the system, you must first check to make sure oil is in the system 
before checking the oil level. Perform the “Oil in System Check” proce-
dure on page 87 before performing the oil level check.

1. Position the vehicle on a level surface.

2. If the engine is cold, start the engine and allow it to idle until the 

engine coolant temperature reaches the specified range. Proceed to 
step 4.

3. If the engine has been running, stop the engine and verify that cool-

ant temperature is within the specified range for performing the oil 
check. Allow the engine to cool if necessary. When the coolant is 
within the specified range, restart the engine and allow it to idle for 
no more than 20 seconds to circulate the oil back into the tank.

4. Turn the engine off.

Tip: Check the oil level within three 

minutes, before the coolant tem-
perature (and oil level) begin to 
drop.

5. Remove the dipstick from the 

oil tank.

6. Clean the dipstick with a clean 

shop towel and reinstall it, 
screwing it in completely.

7. Remove the dipstick and view 

the oil level.

Tip: The oil level reading will be accurate for only one to three minutes after 

turning off the engine. If the oil check isn't completed within three minutes, 
reinstall the dipstick. Restart the engine and allow it to idle for no more than 
20 seconds to circulate the oil back into the tank.
