This guide will walk you through the process step-by-step, ensuring your mower stays in tip-top shape for years to come.
A quick overview: Changing your MTD lawn mower’s oil is essential for engine lubrication and prevents wear and tear. The process involves draining the old oil, replacing the filter, and adding fresh oil.
Getting Started: Gather Your Supplies
Before you get started, you’ll need a few basic tools and supplies:
- New oil: Choose the correct type and viscosity of oil for your mower, as specified in your owner’s manual.
- Oil filter: A new filter is essential for ensuring proper oil flow and cleanliness.
- Oil drain pan: This will catch the old oil and prevent spills.
- Wrench: This is used to loosen the drain plug.

- Safety glasses: Shield your eyes from potential splashes.
- Clean rags: For wiping up spills and cleaning tools.
- Owner’s manual: Refer to it for specific instructions and recommended oil type for your model.
Preparing Your MTD Lawn Mower for an Oil Change
1. Safety First:
- Cool it down: Let the mower cool completely after use before attempting an oil change. This is crucial for preventing burns from hot engine parts.
- Choose a level surface: Park your mower on a level surface. This ensures that the oil drains properly.
- Disconnect the spark plug: To prevent accidental starting, always disconnect the spark plug wire before beginning any maintenance work.
2. Locate the Drain Plug and Oil Filler:
- Open the owner’s manual: Your owner’s manual will show you the location of the drain plug and oil filler on your specific model.
- Clean the area: Clean the area around the drain plug and filler cap to prevent dirt from contaminating the oil.
Draining the Old Oil
1. Position the Drain Pan:
- Place the drain pan securely under the drain plug. This will catch the old oil as it flows out.
2. Loosen the Drain Plug:
- Using the wrench, carefully loosen the drain plug. It may be tight, so use caution to avoid stripping the threads.
- Let the oil drain: Allow the oil to drain completely into the pan. It’s best to let it drain for at least 10 minutes.
3. Tighten the Drain Plug:
- Once the oil has finished draining, use the wrench to tighten the drain plug back to its original position.
Replacing the Oil Filter
1. Locate the Oil Filter:
- Your owner’s manual will show you the location of the oil filter. It’s usually found near the engine.
- Remove the old filter: Use a filter wrench or pliers to loosen and remove the old filter.
2. Install the New Filter:
- Apply a thin layer of fresh oil to the rubber seal of the new oil filter.
- Screw the new filter on by hand until it’s snug. Don’t over-tighten, as this can damage the filter.
Adding Fresh Oil
1. Locate the Oil Filler:
- Refer to your owner’s manual to find the oil filler cap.
2. Fill with New Oil:
- Carefully pour the recommended amount of oil into the filler neck. Check your owner’s manual for the exact oil capacity of your mower.
- Do not overfill: Overfilling can damage your engine.
3. Check the Oil Level:
- After adding the oil, pull out the dipstick to check the oil level. It should be within the “Full” mark on the dipstick.
Finishing Touches
1. Replace the Filler Cap:
- Securely screw the filler cap back onto the oil filler neck.
2. Connect the Spark Plug:
- Reconnect the spark plug wire to the spark plug.
3. Dispose of Used Oil Properly:
- Do not pour used oil down the drain or into the ground. Dispose of it properly at a designated collection site.

Frequently Asked Questions
The oil in your lawn mower engine acts as a lubricant, protecting the moving parts from wear and tear. It also helps to cool the engine and remove any debris. Over time, the oil breaks down and loses its effectiveness. This can lead to engine damage, reduced performance, and a shorter lifespan for your mower. Changing the oil regularly ensures that your engine is properly lubricated and protected, keeping it running smoothly and extending its life.
Regular oil changes also prevent dirt and other contaminants from building up in the engine. These contaminants can lead to sludge and varnish buildup, which can hinder engine performance and eventually cause serious damage. By changing the oil according to the manufacturer’s recommendations, you’re taking a proactive step towards keeping your lawn mower in top shape and ensuring years of reliable service.
What type of oil should I use in my lawn mower?
The type of oil you should use for your lawn mower is specified in your owner’s manual. Most gasoline-powered lawn mowers require a 4-stroke engine oil with a specific viscosity rating. These ratings, like 10W-30 or 5W-30, indicate the oil’s performance at different temperatures. Consult your manual for the recommended viscosity for your specific mower and climate.
Using the correct type of oil is crucial for your lawn mower’s health. The wrong type of oil can cause engine damage, especially in extreme temperatures. It’s important to use a high-quality oil that meets the manufacturer’s specifications for optimal performance and longevity.
How often should I change the oil in my lawn mower?
The frequency of oil changes for your lawn mower depends on factors such as the age of the mower, usage, and type of oil used. However, as a general guideline, you should change the oil every 25 hours of operation or once per season, whichever comes first.
Consult your owner’s manual for the specific recommendations for your model. If you use your mower frequently or in challenging conditions, you may need to change the oil more often. Keeping track of your mowing hours and following the manufacturer’s recommendations will help you maintain your lawn mower’s optimal performance.
What tools do I need to change the lawn mower oil?
To change the oil in your lawn mower, you will need a few essential tools:
- Oil drain pan: This is used to catch the old oil as you drain it from the engine.
- Wrench: You’ll need a wrench that matches the size of the oil drain plug.
- Funnel: A funnel makes it easier to pour new oil into the engine without spilling.
- New oil: Choose the correct type and viscosity of oil for your mower as specified in the owner’s manual.
- Gloves: Protect your hands from oil and dirt.
- Shop towels: Used for cleaning up any spills and wiping down the engine.
With these tools, you’ll be well-equipped to perform a successful oil change for your lawn mower.
How do I safely drain the old oil from my lawn mower?
To safely drain the old oil, follow these steps:
- Start by letting the engine cool down. A hot engine can cause burns, and the oil will be thinner, making it harder to drain.
- Place the oil drain pan underneath the drain plug. This will catch the old oil as it drains.
- Use the wrench to loosen and remove the oil drain plug. Be careful not to drop it into the pan.
- Allow the old oil to drain completely. This may take a few minutes.
- Once the oil has drained, replace the drain plug and tighten it securely.
By following these steps, you can safely drain the old oil from your lawn mower without causing any damage or spills.
How do I refill the lawn mower with new oil?
After draining the old oil, it’s time to refill your lawn mower with fresh oil. Follow these steps:
- Locate the oil fill cap. It’s usually located on the top of the engine, often with a dipstick attached.
- Carefully remove the cap and insert the funnel.
- Slowly pour the new oil into the engine. Be careful not to overfill the engine.
- Once the oil level reaches the fill line, remove the funnel and replace the cap.
- Wipe up any spills with a shop towel.
It’s crucial to use the correct type and amount of oil specified in your owner’s manual. Overfilling the engine can cause damage and lead to problems with your lawn mower.
What should I do with the old oil?
Once you have drained the old oil, it’s important to dispose of it properly. Do not pour it down the drain or into the environment, as it can contaminate the water supply and harm wildlife.
Instead, find a designated oil recycling facility in your area. Many auto parts stores and garages accept used motor oil for recycling. Check with your local waste management services for information on disposal options in your community. By properly disposing of the old oil, you are doing your part to protect the environment and ensure responsible waste management.
