Engine Oil and Filter Maintenance for Pro XD 2000D/4000D

Always check and change the oil at the intervals outlined in the Periodic Maintenance Chart in your Owner's Manual. Always use the recommended engine oil, Polaris 5W-40 Synthetic Diesel Oil (part number 2879832). 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. 

To purchase replacement parts and fluids required for an oil change, see your Commercial dealer.

2. Make sure that the vehicle is on a level surface and that the transmission in PARK.

3. Locate the dipstick (1) on the right side of the unit, shown below.

4. Remove the dipstick and wipe it dry with a clean cloth.

5. Reinstall the dipstick and push it into place. Make certain the dipstick is inserted all the way into the dipstick tube to keep the depth of the dipstick consistent.

6. Remove the dipstick and check the oil level.

7. Add the recommended oil as necessary to bring the oil level within the SAFE range on dipstick, shown below. Do not overfill.

Note that a rising oil level between checks during cold weather operation can indicate contaminants such as gas or moisture collecting in the crankcase. If the oil level is over the upper mark, change the oil immediately.

The recommended fluid is 5W-40 Synthetic Diesel Oil (part number 2879832). Both come in quantities of 2 Quarts (1.9 Liters). 

8. With the cargo box raised, add engine oil through the oil fill cap (2) located on top of the valve cover, under the cargo box.
