  • Funnel
  • New oil filter
  • 4-stroke engine oil (check your manual for the correct type)

Step-by-Step Guide

1. Warm Up the Engine

Start the engine and let it run for a few minutes. This helps the oil to warm up, making it easier to drain. Be sure to turn off the engine before proceeding to the next step.

2. Locate the Drain Plug

Find the oil drain plug underneath the engine. Place the drain pan under the plug to catch the old oil.

3. Drain the Old Oil

Use a socket wrench to remove the drain plug. Allow the oil to completely drain into the pan. Once drained, replace the drain plug and tighten it securely.

4. 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. Install the new filter by hand, ensuring it is snug but not overly tight.

5. Add New Oil

Remove the oil fill cap and use a funnel to pour the new oil into the engine. Refer to your owner's manual for the correct oil capacity. Once filled, replace the oil fill cap.

6. Check Oil Level

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