To change the engine oil and filter on your model year 2021 and newer RZR Trail, follow these steps:
1. Park the vehicle on a flat, level surface in a well-ventilated area, and ensure the transmission is in PARK.
2. Start the engine, allow it to warm up at idle for 2 to 3 minutes, and then stop the engine.
3. Pull up on the cargo box panel latch and pivot it up to remove.
4. Carefully clean the area around the oil cap.
5. Remove the oil cap and set it aside.
6. Place a drain pan under the engine crankcase. Placing a rag in the bottom of the drain pan will help prevent the splashing of oil.

8. Remove the drain plug with a 6mm Allen socket, and allow the oil to drain completely. This process will take approximately 15 minutes.
9. Remove the engine access panel by pulling out and pivoting out.
10. Before continuing, position a shop towel underneath the oil filter to catch spillage.
11. Turn the oil filter counterclockwise with a 2.5-inch oil filter wrench to remove.
12. Using a clean, dry cloth, clean the filter sealing surface on the crankcase, and ensure the old O-ring is completely removed.
13. Lubricate the O-ring on the new filter with a film of fresh engine oil, and ensure the O-ring is in good condition.
14. Install the new filter and rotate it clockwise by hand until the filter gasket contacts the sealing surface. Then turn it an additional three-quarters of a turn. The oil filter is part number 2540086.
15. Once the filter is installed, wipe up any residual oil. Ensure there are no shop towels left on the engine.
16. Clean any dirt or debris from the drain plug, and ensure the sealing surfaces are free of any burrs, nicks or scratches.

18. Reinstall the drain plug. Torque to 12 ft-lbs (16 Nm).
19. Before continuing, clean any residual oil off the vehicle.
