NOTE: We used the Polaris oil change kit for service on a 2009 Polaris Sportsman 850XP, but you can buy the oil and filter separately. However, the kit conveniently includes everything you need, and it’s cheaper than purchasing the oil and filter individually.

Changing Polaris ATV Engine Oil

Step 1. Run the engine for a minute to warm the oil, which helps it drain easier.

Step 2. Remove the oil fill cap/dipstick from the top of the frame, which helps the crankcase vent and the oil to drain faster.

Step 8. Reinstall the oil fill cap/dipstick, then start the engine and let it idle for half a minute to distribute the oil within the engine. 

Step 9. Shut off the engine and let it sit for a minute so the oil can settle.

Step 10. Remove the oil fill cap/dipstick, then check the oil level by resting the dipstick on the crankcase threads without screwing it in. Top off the oil if necessary, then reinstall the oil fill cap/dipstick and you’re done.
