1. Prepare Your ATV

Ensure your ATV is on a level surface and the engine is cool. This prevents burns and ensures accurate oil drainage.

Place the drain pan under the engine. Use a socket wrench to remove the drain plug located at the bottom of the engine. Allow the old oil to completely drain into the pan.

Once the oil has fully drained, reinstall the drain plug and tighten it securely with the socket wrench.

Using a funnel, pour the new engine oil into the oil fill cap located on the top of the engine. The 2021 Polaris Sportsman 850 TRAIL typically requires about 2 quarts of oil, but check your owner's manual for the exact amount.
