The smell of freshly cut grass, the satisfying hum of a well-maintained engine, and the feeling of accomplishment after a hard day’s work in your yard – these are the joys of owning a lawn mower. But just like any machine, your lawn mower needs regular maintenance to keep it running smoothly and prevent costly repairs down the line. One of the most important tasks is changing the oil. This article will walk you through the process of changing your lawn mower oil, step-by-step, so you can keep your mower running like a dream.
Changing the oil in your lawn mower is a simple process that any homeowner can do. It requires only a few basic tools and a little time. Regular oil changes will help to keep your mower’s engine clean, prevent wear and tear, and ensure that your mower runs at peak performance.
Getting Started: What You’ll Need
Before you begin, gather the following supplies:
- New lawn mower oil: The type of oil you need will depend on your mower’s engine. Consult your owner’s manual for the correct oil type and viscosity.
- Oil filter (if applicable): Some lawn mowers have oil filters that should be changed along with the oil.
- Oil drain pan: This will catch the used oil.
- Wrench or socket to remove the drain plug.
- Gloves to protect your hands from the hot oil.
- Rag to clean up any spills.
- A level surface: Find a flat, stable area to work on, preferably a driveway or patio.
How to Change the Oil in Your Lawn Mower:
1. Prepare Your Work Area
- Safety First: Ensure the engine is completely cool before you start. Never change the oil while the engine is hot, as this could result in burns.
- Clear the Work Area: Remove any debris or obstructions around your lawn mower.
- Level the Mower: Position the mower on a level surface to ensure that all of the oil drains properly.
2. Locate the Oil Drain Plug and Fill Cap
- Owner’s Manual is Your Guide: Your lawn mower’s owner’s manual will provide detailed diagrams and instructions for locating the drain plug and fill cap. If you don’t have the manual, you can usually find a digital version online.
- Typical Location: The drain plug is often located at the bottom of the engine crankcase, while the fill cap is usually found on the top or side of the engine.
3. Remove the Drain Plug
- Use the Correct Tool: The drain plug may require a wrench or socket depending on its size and design.
- Be Careful: Be sure to have the oil drain pan positioned directly beneath the drain plug to catch the old oil.
- Let it Drain: Allow the oil to drain completely. It might take a few minutes for all of it to come out.
4. Remove the Oil Filter (If Applicable)
- Filter Location: If your lawn mower has an oil filter, it will be located near the engine block.
- Remove Carefully: Use a filter wrench to loosen the oil filter. Once it is loose, you should be able to remove it by hand.
- Clean the Area: Clean any spilled oil from the area where the filter was located.
5. Replace the Drain Plug
- Tighten Securely: Use the wrench or socket to tighten the drain plug back into place. Be sure to tighten it firmly to prevent leaks.
6. Install a New Oil Filter (If Applicable)
- Lube the Seal: Apply a small amount of new oil to the oil filter seal.
- Install Securely: Screw the new oil filter on by hand until it is snug. Do not overtighten the filter.
7. Add New Oil
- Check the Manual: Refer to your owner’s manual for the correct amount of oil to add.
- Pour Slowly: Pour the new oil slowly into the fill cap. Avoid overfilling, as this can cause damage to your engine.
8. Check the Oil Level
- Dip the Dipstick: Once you’ve added the oil, use the dipstick to check the oil level. Wipe the dipstick clean, insert it fully into the oil fill tube, and then remove it to check the level.
- Adjust as Needed: If the oil level is low, add more oil until it reaches the full mark on the dipstick.
9. Clean Up and Dispose of Used Oil
- Wipe Down: Clean up any oil spills around the engine.
- Dispose Properly: Never pour used oil down the drain. Dispose of it properly at a local recycling center or auto parts store.
Tips for Maintaining Your Lawn Mower
- Regular Oil Changes: Change the oil in your lawn mower every 25 hours of operation, or more often if you use it frequently in dusty or harsh conditions.
- Fuel Storage: Store fuel in a clean, sealed container. Fresh fuel will help your engine run smoothly.
- Air Filter: Clean or replace the air filter regularly to prevent dirt and debris from entering the engine.
- Spark Plug: Replace the spark plug as recommended in your owner’s manual.
- Blade Sharpening: Sharpen your lawn mower blades every few months for a cleaner cut and a healthier lawn.

1. The Oil Won’t Drain

Frequently Asked Questions
What type of oil should I use for my lawn mower?
The type of oil you need for your lawn mower will depend on the engine type. Most modern lawn mowers have 4-stroke engines, which require 10W-30 or 10W-40 motor oil. You can find this information in your owner’s manual or on the engine itself. It’s important to use the correct type of oil, as using the wrong type can damage your engine.
Always check your owner’s manual for specific recommendations. Using the wrong type of oil could lead to engine problems. For example, using a heavier oil in cold weather can make it difficult for your engine to start, while using a lighter oil in hot weather can cause it to overheat.
How often should I change the oil in my lawn mower?
The frequency of oil changes varies depending on the usage. For regular use, it’s recommended to change the oil every 25 hours of operation or at least once per season. If you use your lawnmower extensively, you may need to change the oil more often. A good rule of thumb is to check the oil level before each use and change the oil when it’s dirty or black.
Keeping track of your lawnmower’s operating hours can help you determine when to change the oil. If you don’t know the exact hours, consider changing the oil once a year. Also, keep an eye out for signs of oil needing a change, such as the oil appearing dark or thick, smelling burnt, or having metal shavings in it.
What tools do I need to change the oil in my lawn mower?
You will need a few basic tools to change the oil in your lawn mower. These include a wrench or socket to remove the drain plug, a container to collect the used oil, a funnel, and a new oil filter if your mower has one. You may also want to have some rags or paper towels on hand to clean up any spills.
Having the right tools will make the process much easier. You can usually find all the necessary tools at a local hardware store. It’s also a good idea to have a few pairs of gloves to keep your hands clean.
How do I dispose of the used oil properly?
It’s important to dispose of used oil properly to protect the environment. Never pour it down the drain or on the ground. You can take it to a local recycling center or auto parts store that accepts used oil for recycling. Some communities offer hazardous waste collection days where you can dispose of used oil.
Check with your local municipality to find out about specific disposal regulations in your area. Some communities may offer free drop-off locations for used oil or have programs that allow you to exchange used oil for new oil.
What should I do if I accidentally spill oil?
If you accidentally spill oil, clean it up immediately to prevent it from contaminating the environment. Use absorbent materials like rags or paper towels to soak up the spilled oil. Dispose of the contaminated materials properly, as they should not be thrown in the trash.
Once you’ve cleaned up the spill, consider using a degreaser to remove any remaining oil residue. Always wear gloves when handling spilled oil and dispose of used rags and towels properly.
Is it necessary to change the oil filter when changing the oil?
If your lawnmower has an oil filter, it’s recommended to change it every other oil change. This will help to keep your engine running smoothly and prevent any dirt or debris from building up in the oil.
Some oil filters are designed to last longer than others, so it’s always a good idea to check your owner’s manual for specific recommendations. A dirty oil filter can cause your engine to overheat or lose power, so it’s important to change it regularly.
Can I change the oil myself, or should I take it to a professional?
Changing the oil in your lawnmower is a relatively simple task that most people can do themselves. However, if you’re unsure about any part of the process, it’s always best to err on the side of caution and take it to a professional.
If you’re not comfortable with working on machinery or if you don’t have the necessary tools, it’s best to leave the oil change to a qualified mechanic. They can ensure that the job is done correctly and can also check for any other maintenance issues.
