Tools and Materials Needed

  • Oil filter
  • 4 quarts of 5W-50 synthetic oil
  • Oil drain pan

  • Funnel
  • Clean rags

Step-by-Step Guide

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.

2. Remove the Drain Plug

Locate the oil drain plug under the engine. Place the oil drain pan beneath it. Use a socket wrench to remove the drain plug and allow the old oil to completely drain into the pan.

3. Replace the Oil Filter

While the oil is draining, locate the oil filter. Use an oil filter wrench to remove the old filter. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the top of the filter. Screw the new filter into place by hand until it's snug.

4. Reinstall the Drain Plug

Once the oil has fully drained, reinstall the drain plug. Tighten it securely with the socket wrench, but be careful not to overtighten.

5. Add New Oil

Remove the oil fill cap and insert a funnel. Pour in the new 5W-50 synthetic oil. The 2011 Polaris Sportsman 400 H.O. 4X4 typically requires about 2 quarts, but check your owner's manual for the exact capacity. Replace the oil fill cap once done.

6. Check Oil Level

Start the engine and let it run for a few minutes. Turn it off and wait a couple of minutes for the oil to settle. Use the dipstick to check the oil level and add more if necessary.
