The roar of a lawnmower is a familiar summer sound, but keeping your Tecumseh-powered mower running smoothly requires more than just gas and a sharp blade. Regular oil changes are crucial for maintaining engine health and preventing costly repairs. This article will walk you through the process of changing the oil in your Tecumseh lawnmower, ensuring your mower stays in top condition for years to come.
Changing the oil in your Tecumseh lawn mower is a straightforward process that anyone can do with a few basic tools and supplies. This guide will cover everything from the necessary tools and materials to the step-by-step instructions for changing the oil.
Getting Started: Gathering the Essentials
Before you get your hands dirty, ensure you have all the necessary tools and materials readily available. Here’s what you’ll need:
- New engine oil: Consult your mower’s owner’s manual for the recommended type and viscosity of oil.
- Oil drain pan: This will catch the old oil.
- Wrench: A wrench that fits the oil drain plug.
- Oil filter wrench (optional): Some Tecumseh mowers use an oil filter, and this wrench is required to remove it.
- Clean rags: For wiping up spills and cleaning parts.
- Gloves: Protect your hands from oil and grime.
- Safety glasses: Protect your eyes from oil splashes.
- Funnel: For pouring fresh oil into the engine.
Preparing Your Tecumseh Lawn Mower
Once you’ve gathered your supplies, it’s time to get your Tecumseh lawnmower ready for the oil change.
1. Finding the Oil Drain Plug
Locate the oil drain plug on the bottom of the engine. It’s usually a round plug with a bolt head that you can access with a wrench.
2. Warming Up the Engine (Optional)
While not strictly necessary, warming up the engine for a few minutes can make the oil thinner and easier to drain. This is especially helpful if the oil has been in the engine for a long time.
3. Positioning the Mower for Drainage
Place your mower on a level surface. If your mower has a catch pan, ensure it’s positioned to collect the drained oil.
Changing the Oil: A Step-by-Step Guide
Now that your mower is prepped, follow these steps for a smooth oil change:
1. Drain the Old Oil
Using the Wrench
Place the appropriate wrench on the oil drain plug and loosen it by turning it counter-clockwise. Be careful not to over-tighten the wrench as you turn it.
Removing the Oil Drain Plug
Once the drain plug is loose, remove it entirely and let the oil drain completely into the oil drain pan.
2. Inspect the Oil Filter (Optional)
If your Tecumseh lawnmower has an oil filter, carefully unscrew it using the oil filter wrench.
Inspecting the Oil Filter
If the filter looks worn or dirty, it’s time to replace it. Check your owner’s manual for the correct oil filter size for your mower.
3. Replace the Oil Drain Plug
Once the old oil is drained, clean the drain plug and the surrounding area with a clean rag. Screw the drain plug back into place, making sure it’s securely tightened. Avoid over-tightening.
4. Install New Oil Filter (Optional)
If you’re replacing the oil filter, thread the new filter onto the filter housing by hand until it’s snug. Then, use the oil filter wrench to tighten it an additional quarter turn.
5. Add Fresh Oil
With the old oil drained and the filter replaced, it’s time to add fresh oil.
Using the Funnel
Use the funnel to pour the recommended amount of fresh oil into the engine’s oil fill opening. Check your owner’s manual for the specific oil capacity of your mower.
Double-Checking the Oil Level
Once you’ve added the oil, check the oil level using the dipstick on the side of the engine.
6. Wipe Down the Engine
Use a clean rag to wipe up any oil spills or drips around the engine.
7. Start and Check for Leaks
Start the engine and let it run for a few minutes. Check for any leaks around the drain plug and oil filter.
Checking for Leaks
If you see any leaks, stop the engine and tighten the drain plug or oil filter further.
8. Dispose of Old Oil Responsibly
Dispose of the old oil responsibly by taking it to a local recycling center or auto parts store.

FAQ
1. How often should I change the oil in my Tecumseh lawn mower?
You should change the oil in your Tecumseh lawn mower every 25 hours of operation or once per season, whichever comes first. This is because the oil breaks down over time and loses its ability to lubricate the engine properly. This can lead to engine damage, which can be costly to repair.
Regular oil changes help maintain the health and performance of your mower engine. By following the recommended schedule, you can prevent potential problems and extend the lifespan of your equipment.
2. What kind of oil should I use in my Tecumseh lawn mower?
You should use a high-quality 4-stroke oil specifically designed for air-cooled lawn mower engines. The best type is a SAE 30 oil, which is formulated for engines that operate at high temperatures. Avoid using automotive oil, as it is not designed for air-cooled engines and can lead to engine damage.
Ensure you choose an oil that meets the specifications outlined in your Tecumseh lawn mower’s user manual. This will ensure the appropriate viscosity and quality of oil for optimal performance and longevity of your engine.
3. What tools do I need to change the oil in my Tecumseh lawn mower?
You will need a few basic tools to change the oil in your Tecumseh lawn mower. These include a wrench or socket that fits the oil drain plug, a drain pan or container, a funnel, and some rags or paper towels. It’s also recommended to have a new oil filter on hand if your mower has one.
Having the right tools readily available will ensure a smooth and efficient oil change process. You may also want to wear gloves and safety goggles to protect yourself from oil spills and potential debris.
4. Where is the oil drain plug located on my Tecumseh lawn mower?
The oil drain plug is typically located on the bottom of the engine block. Look for a small, threaded plug that is usually made of metal. There might be a sticker or inscription on the engine indicating the drain plug’s location.
If you’re unsure where it is, consult your lawn mower’s user manual for a diagram. The manual will clearly indicate the location of the oil drain plug for your specific Tecumseh engine model.
5. How much oil should I put in my Tecumseh lawn mower?
The amount of oil required for your Tecumseh lawn mower will vary depending on the engine model. You can find the recommended oil capacity in your lawn mower’s user manual. Typically, most Tecumseh engines require between 18 and 24 ounces of oil.
Overfilling the engine with oil can be just as detrimental as underfilling it, so it’s crucial to follow the manufacturer’s specifications for optimal engine performance.
6. Can I change the oil in my Tecumseh lawn mower without draining the old oil?
It is not recommended to change the oil without draining the old oil. Even though you’re adding fresh oil, the old oil will still be mixed in, diminishing the effectiveness of the new oil.
Draining the old oil ensures that you’re replacing it with fresh, clean oil, which is crucial for optimal engine lubrication and performance.
7. What should I do with the old oil?
Old oil should never be poured down the drain or into the environment. Instead, it should be recycled properly. Many auto parts stores and other businesses offer oil recycling services. You can also check with your local waste management agency for information on oil disposal options.
Proper disposal of used oil is essential for protecting the environment. It’s important to follow local regulations and guidelines for responsible waste management.
