Changing the oil on a Murray lawn mower is a relatively straightforward process. You will need to gather a few basic tools and supplies, and the entire process should take you about 30 minutes. In this article, we’ll cover the necessary tools, how to prepare your mower, and the step-by-step process for changing the oil, including disposal of used oil.
Gathering Your Supplies: What You’ll Need
Before you dive into changing the oil, make sure you have all the necessary tools and supplies.
Essential Tools:
- Oil Drain Pan: This will catch the old oil as you drain it from the mower.
- Wrench or Socket: You’ll need a wrench or socket that fits the oil drain plug on your mower. This size will vary depending on your model, so check your owner’s manual.
- New Engine Oil: Purchase the correct type and viscosity of oil for your mower. This information is typically found in your owner’s manual or on a sticker on your mower.
- Funnel: This will make pouring the new oil into the engine easier.
- Gloves: Wearing gloves protects your hands from getting dirty.
- Rag or Paper Towels: These will be handy for cleaning up spills.
Optional Tools:
- Oil Filter Wrench: Some Murray lawn mowers use an oil filter, and you’ll need a wrench specifically designed for removing and installing the filter.
Preparing Your Murray Lawn Mower for an Oil Change
Once you have all your supplies, it’s time to prepare your mower for the oil change:
1. Safety First:
- Park on a Level Surface: Ensure your mower is parked on a level surface to prevent oil spills.
- Turn Off the Engine: Always allow your mower to cool down completely before starting any maintenance work.
2. Locate the Oil Drain Plug and Fill Hole:
- Consult Your Owner’s Manual: Refer to your owner’s manual to locate the precise position of the oil drain plug and the oil fill hole on your specific model. The drain plug is usually located at the bottom of the engine, while the fill hole is often on the side or top of the engine.
3. Position the Oil Drain Pan:
- Under the Engine: Place the oil drain pan directly beneath the oil drain plug to catch the draining oil.
The Step-by-Step Oil Change Process:
Now that your mower is prepared, you can begin the oil change process:
1. Loosen the Oil Drain Plug:
- Wrench or Socket: Using the appropriate wrench or socket, carefully loosen the oil drain plug, turning it counterclockwise. Be cautious as oil will start to flow as soon as you loosen the plug.
2. Allow the Oil to Drain:
- Complete Drainage: Allow the oil to drain completely into the oil drain pan. It’s a good idea to wait a few minutes to ensure all the old oil is drained.
3. Reinstall the Oil Drain Plug:
- Tighten Securely: Once the oil has drained, carefully reinstall the oil drain plug, tightening it securely with the wrench or socket. Do not overtighten it as this could damage the drain plug or the engine casing.
4. Dispose of Old Oil:
- Proper Disposal: Dispose of the used oil responsibly. Check with your local municipality or a nearby auto parts store to find out where you can dispose of used oil in your area. Avoid pouring it down the drain or onto the ground, as it can harm the environment.
5. Add New Oil:
- Correct Oil Type: Using a funnel, carefully pour the correct amount and type of engine oil into the oil fill hole. Refer to your owner’s manual for the recommended amount of oil for your specific model.
6. Check the Oil Level:
- Dip Stick: Use the oil dipstick to check the oil level. The oil level should be between the “full” and “low” marks on the dipstick.
7. Clean Up:
- Wipe Spills: Wipe away any oil spills with a rag or paper towels.
8. Start the Engine:
- Run for a Few Minutes: Start the engine and let it run for a few minutes to ensure the oil circulates properly.
Additional Tips:
- Oil Filter Replacement: If your Murray lawn mower has an oil filter, you should also replace it during an oil change. Refer to your owner’s manual for instructions on how to remove and replace the oil filter.
- Frequency of Oil Changes: The frequency of oil changes for a lawn mower depends on usage. Generally, you should change the oil every 25 hours of operation or at least once per season.
- Owner’s Manual: Always refer to your owner’s manual for specific instructions and recommendations for your Murray lawn mower model.
Conclusion:
Changing the oil on your Murray lawn mower is a simple yet important maintenance task that keeps your mower running smoothly and extends its lifespan. By following these steps and gathering the necessary supplies, you can confidently perform this maintenance routine yourself and ensure your mower continues to provide you with reliable service for years to come. Remember to dispose of used oil responsibly and always consult your owner’s manual for model-specific instructions.
