The satisfying hum of a well-maintained lawn mower is a welcome sound in any backyard. But like any piece of machinery, your mower needs regular upkeep, and changing the oil is a crucial part of that. A dirty oil can lead to engine wear and tear, eventually leading to costly repairs. This guide will walk you through the entire process of draining your lawn mower oil, from gathering the necessary tools to disposing of the old oil responsibly.
In essence, draining your lawn mower oil is a simple procedure, but it’s important to follow the proper steps to avoid spills and ensure your mower runs smoothly. This guide will cover how to choose the right oil, identify the drain plug, prepare the workspace, and safely dispose of the old oil.
Choosing the Right Oil
Before you start draining, it’s essential to use the correct oil for your lawn mower. The type of oil required depends on the engine type and the manufacturer’s recommendations.
Checking Your Owner’s Manual
The best place to find the right oil for your mower is your owner’s manual. It will detail the recommended oil type, viscosity (SAE number), and capacity.
Understanding Oil Types and Viscosities
- SAE (Society of Automotive Engineers) Numbers: These numbers represent the viscosity, or thickness, of the oil. For example, SAE 30 is a common oil for lawn mowers, but your manual may recommend a different viscosity depending on your climate and the type of engine.
- Synthetic vs. Conventional: Synthetic oils offer better protection and performance, but they are more expensive. Conventional oil is a less expensive option, but it may not last as long.
Identifying the Drain Plug
The drain plug is usually located on the bottom of the engine, near the oil pan. It’s typically a hexagonal or square-shaped plug with a small hole in the center.
Locating the Drain Plug
- Consult Your Manual: Your owner’s manual will show the location of the drain plug.
- Visual Inspection: Look for a plug on the bottom of the engine with a slight indentation around the center.
- Feel Around: Gently feel around the bottom of the engine for a plug that feels different from the rest of the casing.
Preparing Your Workspace
Once you have located the drain plug, it’s time to prepare the workspace. A clean and organized space makes the process safer and easier.
Gather Your Tools
- Drain Pan: A large, flat-bottomed pan to catch the used oil.
- Wrench: A wrench that fits the size of the drain plug. You might need a combination wrench for easier turning.
- Gloves: To protect your hands from the hot oil and dirt.
- Old Towels: To catch spills and clean up any messes.
- Funnel: To pour the used oil into a disposal container.
Choose a Safe and Level Surface
- Level Ground: Position your mower on a flat and level surface to avoid any spills.
- Well-Ventilated Area: Make sure the area is well-ventilated to avoid inhaling oil fumes.
Draining the Oil
Now, it’s time to drain the oil. Follow these steps carefully to prevent spills and ensure a clean drain.
Warm Up the Engine
Before draining, run the engine for a few minutes to warm up the oil. This helps the oil flow more easily and allows for a more complete drain.
Loosen the Drain Plug
Carefully loosen the drain plug using your wrench. Be sure to turn it counter-clockwise.
Drain the Oil
As the oil starts to drain, carefully remove the drain plug and allow the oil to drain completely into the drain pan.
Replace the Drain Plug
Once the oil has stopped dripping, replace the drain plug and tighten it securely using your wrench. Do not overtighten it, as this could damage the plug or the oil pan.
Refilling the Oil
After draining the old oil, it’s time to refill the engine with fresh oil.
Clean the Drain Plug
Before reinstalling the drain plug, clean it with a rag or paper towel.
Add New Oil
Pour the recommended amount of fresh oil into the engine using a funnel. Be sure to check the oil level with the dipstick after filling.
Run the Engine Briefly
Once the new oil is in, start the engine for a few minutes to allow the oil to circulate and lubricate all parts.
Disposing of the Used Oil
Used motor oil is hazardous and should not be poured down drains or into the environment.
Find an Oil Recycling Center
Most communities have designated oil recycling centers. You can check online or contact your local waste management department to find a location near you.
Dispose of the Oil Properly
Once you have found a recycling center, carefully pour the used oil into a container designed for this purpose. The containers should be labeled “Used Oil” and are available at most auto parts stores and recycling centers.

FAQs
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 type of oil used, the hours of operation, and the age of the mower. However, as a general rule, you should change the oil at least once a year, or after every 25 hours of use. This ensures that your mower engine is well-lubricated and runs smoothly.
Failing to change the oil regularly can lead to engine wear and tear, decreased performance, and ultimately, costly repairs.
What kind of oil should I use for my lawn mower?
The best type of oil for your lawn mower is specified in the owner’s manual. Most gasoline-powered lawn mowers use SAE 30 oil for normal temperatures, but you might need to switch to SAE 10W-30 for colder weather. Always use a high-quality oil that meets the requirements of your mower’s engine.
It is important to use the correct oil type because using the wrong oil can damage your mower’s engine.
What tools do I need to drain the oil?
You will need a few basic tools to drain the oil from your lawn mower. These include a drain pan or container to collect the used oil, a wrench or socket to loosen the drain plug, and a funnel for adding new oil. It is also helpful to have gloves, rags, and paper towels for cleaning up any spills.
Make sure to dispose of the used oil properly, as it is hazardous to the environment.
Where is the drain plug located on my lawn mower?
The drain plug is usually located at the bottom of the engine block, near the oil filter. It may be hidden by a metal plate or a plastic cover. Consult your owner’s manual for the exact location of the drain plug on your specific lawn mower model.
If you can’t find the drain plug, you can ask a mechanic for help.
What should I do after draining the oil?
After you have drained the old oil, replace the drain plug and tighten it securely. Now, you can add fresh oil through the oil filler cap, which is usually located on the top of the engine.
Make sure to add the correct amount of oil as specified in the owner’s manual. Overfilling the engine with oil can cause damage.
Is it safe to drain the oil while the engine is hot?
It is not recommended to drain the oil while the engine is hot, as the hot oil can burn you. Always allow the engine to cool down completely before attempting to drain the oil.
It is also important to wear gloves and protective eyewear when handling hot oil.
How do I dispose of the used oil properly?
Used motor oil is a hazardous substance and should not be disposed of in the trash or poured down the drain. Instead, you can take it to a local auto parts store or recycling center that accepts used oil.
Some communities also have designated oil recycling drop-off points. Always check with your local authorities for the proper disposal methods in your area.
