Tools and Materials Needed

  • Socket set
  • Drain pan
  • Funnel
  • New oil filter
  • 4-stroke engine oil (check your manual for the recommended type)
  • Rags or paper towels

Step-by-Step Guide

1. Prepare Your ATV

Ensure your ATV is on a level surface and the engine is cool. This will prevent burns and ensure all the old oil drains out completely.

2. Drain the Old Oil

Locate the oil drain plug under the engine. Place the drain pan beneath it. Use a socket wrench to remove the drain plug and allow the old oil to completely drain into the pan. Once drained, replace the drain plug and tighten it securely.

3. Replace the Oil Filter

Use the oil filter wrench to remove the old oil filter. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the top of the filter. This ensures a good seal. Install the new filter by hand, tightening it securely.

4. Add New Oil

Remove the oil fill cap and insert a funnel. Pour the recommended amount of new oil into the engine. Check your owner's manual for the exact oil capacity. Once filled, replace the oil fill cap.

5. Check for Leaks

Start the engine and let it run for a few minutes. Check around the oil filter and drain plug for any leaks. If you notice any, turn off the engine and tighten the components as necessary.

6. Dispose of Old Oil

Properly dispose of the old oil and filter at a recycling center or an auto shop that accepts used oil.
