The roar of your lawnmower is a familiar sound of summer, but like any hardworking machine, it needs regular maintenance to keep it running smoothly. One of the most important tasks is changing the oil, a simple process that can significantly extend the life of your mower. This guide will walk you through everything you need to know about changing your lawnmower oil, from choosing the right oil to safely disposing of the old oil.
The Importance of Changing Your Lawn Mower Oil
Just like the oil in your car, the oil in your lawnmower lubricates the moving parts, preventing wear and tear. Over time, this oil breaks down, becoming contaminated with dirt and debris. This dirty oil can hinder the engine’s performance, leading to overheating, reduced power, and even engine damage. Regular oil changes help to keep your lawnmower running efficiently and prevent costly repairs.
Getting Started: Gather Your Supplies
Before you start, make sure you have all the necessary tools and supplies. You’ll need:
- Fresh lawnmower oil: Always consult your owner’s manual for the recommended type and viscosity of oil for your specific mower.
- Oil drain pan: This will catch the old oil as you drain it.
- Wrench: You’ll need a wrench that fits the oil drain plug on your mower.
- Oil filter wrench (optional): If your mower has an oil filter, you’ll need this to remove it.
- New oil filter (optional): If you’re replacing the oil filter, make sure you have a new one that fits your mower.
- Gloves: Protect your hands from oil and dirt.
- Clean rags: For wiping up spills and cleaning the area.
Finding the Oil Drain Plug: A Quick Look Under the Hood
The oil drain plug is usually located on the bottom of the engine block. It’s often a square or hexagonal plug, easily identifiable by its size and position. Your owner’s manual will provide a specific location for your model, as well as any other instructions specific to your mower.
Step-by-Step Guide to Changing Your Lawn Mower Oil
Now that you’ve gathered your supplies and located the oil drain plug, you’re ready to start the oil change:
1. Warm Up the Engine
Start the engine and let it run for a few minutes to warm up the oil. This will make it flow more easily and ensure you drain most of the old oil.
2. Prepare Your Work Area
Choose a flat, stable surface to work on. Place the oil drain pan underneath the oil drain plug to catch the used oil.
3. Locate and Remove the Oil Drain Plug
Use your wrench to loosen the oil drain plug, turning it counterclockwise. Be careful not to overtighten the plug when you reinstall it.
4. Drain the Oil
Let the oil drain completely into the pan. This may take a few minutes. If you have an oil filter, remove it using the oil filter wrench.
5. Replace the Oil Drain Plug
Clean the oil drain plug with a clean rag and re-install it, tightening it by hand.
6. Refill with New Oil
Carefully pour the recommended amount of fresh oil into the oil fill hole. You’ll find the oil fill hole on the top of the engine.
7. Check the Oil Level
Start the engine for a few minutes to allow the oil to distribute. Then, check the oil level using the dipstick. If the oil level is too low, add more oil. If it’s too high, remove some using a syringe or turkey baster.
8. Dispose of Used Oil Properly
Dispose of the old oil properly. Many local recycling centers will accept used motor oil, or you can check with your local waste management company for disposal instructions.
Optional: Replacing the Oil Filter
If your mower has an oil filter, it’s a good idea to replace it with a new one during every oil change. This will help to keep your engine clean and running smoothly.
1. Locate the Oil Filter
The oil filter is usually located near the top of the engine, attached to the engine block.
2. Remove the Old Filter
Use the oil filter wrench to loosen the oil filter, turning it counterclockwise.
3. Clean the Filter Housing
Clean the filter housing with a clean rag to remove any old oil or debris.
4. Install the New Filter
Apply a thin coat of fresh oil to the rubber seal on the new filter. Hand-tighten the new filter onto the filter housing until it’s snug.
Tips for a Successful Oil Change
- Read Your Owner’s Manual: Always refer to your owner’s manual for specific instructions and recommendations for your mower model.
- Wear Safety Glasses: Protect your eyes from oil splashes and debris.
- Work in a Well-Ventilated Area: Avoid working in an enclosed space where engine fumes can build up.
- Clean Up Any Spills: Immediately clean up any spilled oil to prevent contamination and environmental harm.
- Schedule Regular Oil Changes: Consult your owner’s manual for recommended oil change intervals, but most lawnmowers require an oil change every 25 hours of use or once per season.

FAQ
Why should I change the oil in my lawn mower?
Changing the oil in your lawn mower is essential for its longevity and performance. Old oil breaks down and loses its lubricating properties, leading to increased friction and wear on engine components. This can result in decreased power, increased fuel consumption, and even engine damage. Regular oil changes ensure that your lawn mower runs smoothly and efficiently, extending its lifespan.
How often should I change the oil in my lawn mower?
The frequency of oil changes depends on the type of lawn mower and its usage. For gasoline-powered lawn mowers, a general recommendation is to change the oil every 25 hours of operation or at the end of each mowing season. If you use your lawn mower frequently or in hot weather, it’s best to change the oil more often. Refer to your owner’s manual for specific recommendations.
What type of oil should I use in my lawn mower?
The type of oil you use depends on the manufacturer’s recommendations for your lawn mower. Typically, lawn mower engines require 4-stroke oil specifically designed for air-cooled engines. Check your owner’s manual for the recommended viscosity and type of oil, such as SAE 30 or SAE 10W-30. Avoid using oil formulated for cars or other engines as they may not be suitable for lawn mowers.
