Tools and Materials Needed
Before you begin the oil change process, gather the necessary tools and materials:
- Oil drain pan: To catch the old oil.
- Wrench or socket set: For removing the oil drain plug.
- Funnel: To pour the new oil without spills.
- Clean rag: For wiping down surfaces and checking the dipstick.
- New oil: Choose an appropriate oil like STP Premium Small Engine 4 Cycle Oil.

Step-by-Step Instructions for Changing Lawn Mower Oil
Follow these steps to change your lawn mower oil:
- Prepare the mower: Ensure your mower is on a flat surface. Turn off the engine and let it cool completely before starting the oil change.
- Locate the oil drain plug: Check your owner’s manual if you’re unsure where it is. It’s usually at the bottom of the engine.
- Drain the old oil: Place the oil drain pan under the drain plug. Remove the plug and let the old oil flow into the pan. This may take a few minutes.
- Replace the oil filter (if applicable): If your mower has an oil filter, remove it using an oil filter wrench. Pre-fill the new filter with a little oil and install it securely.
- Replace the drain plug: Once all the old oil has drained, replace the drain plug and tighten it securely.
- Add new oil: Using a funnel, pour the new oil into the filler opening. Check your owner’s manual for the correct oil capacity, typically between 15 to 20 ounces.
- Check the oil level: Wait a minute, then use the dipstick to check the oil level. Add more oil if necessary.
- Start the mower: Start the engine and let it run for a minute. Check for any leaks around the drain plug and filter. Turn off the engine and check the oil level again, topping off as needed.

Common Questions About Changing Lawn Mower Oil
How often should I change my lawn mower oil?
Typically, you should change the oil every 50 hours of operation or at least once a season. If you use your mower heavily, consider changing it more frequently.
What type of oil should I use for my lawn mower?
Most lawn mowers use SAE 10W-30 oil, but it’s best to check your owner’s manual for specific recommendations. For small engines, the best type of oil can vary based on the model.
Can I mix different types of oil?
Avoid mixing different oil types as it can lead to decreased performance. Stick to the same type, whether it’s synthetic or conventional.
What happens if I don’t change the oil?
Not changing the oil can result in engine wear, overheating, and potential engine failure. Dirty oil loses its ability to lubricate, leading to serious damage.
