  • Socket wrench set
  • New engine oil (SAE 10W-40 recommended)
  • Funnel
  • Clean rags

Steps to Change the Oil

  1. Warm Up the Engine: Start the engine and let it run for a few minutes. This helps the oil to flow out smoothly when you drain it.
  2. Locate the Drain Plug: Position your ATV on a level surface. Locate the oil drain plug underneath the engine.
  3. Drain the Oil: Place the oil drain pan under the drain plug. Use a socket wrench to remove the plug and allow the old oil to completely drain out.
  4. Replace the Oil Filter: Remove the old oil filter using an appropriate tool. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the filter. Install the new filter by hand, ensuring it is snug but not overtightened.
  5. Refill with New Oil: Replace the drain plug securely. Use a funnel to pour the new engine oil into the oil fill port. The LT125 typically requires about 1.1 liters of oil. Check the oil level with the dipstick and add more if necessary.
  6. 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. Tighten if necessary.
  7. Dispose of Old Oil: Properly dispose of the old oil and filter at a recycling center or an appropriate waste disposal facility.
