How To Drain Oil From Lawn Mower?

How To Drain Oil From Lawn Mower

The purpose of this post is to help you understand how to drain oil from lawn mower.

The operation of a lawnmower relies on the use of motor oil. Oil provides lubrication to the moving parts of a mower engine so that it functions efficiently. An engine without sufficient oil will not work properly. It will overheat from friction and lock up, and eventually ruining the lawnmower engine.

The basic routine maintenance of a mower includes changing the lawnmower engine’s oil at regular intervals. The used oil is drained from the mower, and new oil is added. This is what oil change is all about. If you want to prolong the life of the mower, make sure that you keep changing the motor oil regularly.

How to drain oil from lawn mower

A mower’s owner’s manual will show how often to perform oil changes on the mower. If we are talking about the minimum, an oil change should be done annually with other seasonal tune-up maintenance. Changing mower oil is very simple and easy. It can take as little as five minutes.

First of all, you have to identify how to drain the oil on your lawn mower. Equipment like a dipstick tube, drain plug or an oil extractor tool can be used for this purpose. 

1. Warm Up the Engine

Park the mower on a hard surface. Afterward, set the parking brake. Warm up the engine for a few minutes and then turn it off. Warming up the mower engine will speed up the oil change. That is because the oil will flow more freely as a result of heating. It will also be a little easier to drain all of the old oil out of the engine. Once the engine has run for quite some time, shut it off. Now, disconnect the spark plug wire so that the mower can’t start accidentally while working on it.

  • Clean around the oil fill area
  • You can use an air compressor or a clean towel to clean up the oil fill area.
  • Prepare an oil pan to catch the oil
  • To catch the oil from the mower, you will need a container or a pan. You better position the pan on the side of the mower to tip it to extract the oil.

2. Drain the Old Oil

First of all, open the mower’s hood. On the right side of the engine, locate the oil drain valve. To expose the drain port, pull the plastic cap off the end of the valve. The dipstick will have to be removed from the oil fill tube. 

Onto the oil drain port, set the drain valve to lose. The oil pan is going to be placed at the end of the drain hose. The oil drain valve will have tabs. Pinch those tabs and pull out. That will let the oil drain.

The oil drain hose is to be removed now. The tabs will click into place as soon as you push the valve. Reinstall the plastic cap on the oil drain valve. 

Now is the time to dispose of the used oil. Make sure you dispose of it after it has cooled down. There are a few places that accept the used motor oil. They may include recycling centre, gas stations and car repair shops.

3. Replacing the Oil Filter

Oil filters are not part of the majority of walk-behind lawnmowers. Nowadays, several models on the market include them in the engine design. You will have to turn the oil filter counterclockwise by hand. Keep turning it until it is removed. The new filter will have a gasket. Use your finger to rub the oil on it. Now turn the filter clockwise. The gasket will touch the oil filter tray. After that, twist an additional 1/2 turn.

4. Add New Oil

Please take out the funnel and fill it with oil from the oil fill tube. Refill the engine with 1-1/2 quarts of new oil. Use the dipstick to check the oil level. Keep adding the oil until the dipstick reads “Full.” Reinsert the dipstick afterwards. Lately, close the hood.

5.Repeat As Needed

Changing the oil should be done every 50 hours of use which equalizes per annum. You also need to keep track of how long it takes you to mow the grass and how often you mow. If you want to begin the mowing season with a functional, efficient and safe mower, change the oil each spring. 

6. Test the Mower

Once you’ve finished the lawnmower oil change, reattach the spark plug wire. Next, add gas to the mower. Start the mower and allow it to run for some time. Make sure the engine is running smoothly. The engine’s running for a few minutes will lubricate the engine parts and distribute the oil throughout the engine.

When to Change the Oil

  • Change oil every 50 hours of operation or after every mowing season.
  • If your engine is new, you will need to change the oil after every five hours of operation.
  • Every time you use the mower, make sure you check the oil. The required oil frequency may change because of certain factors such as wet grass, heavy dust, high temperatures and rough or hilly terrain.

How to Check Oil Level

For getting the most accurate reading, check the oil when the engine is cold, and most of the oil is in the crankcase. Make sure the oil level of the dipstick should be between the two holes on the dipstick. Overfilling the engine can be just as bad as using old oil. That is why make sure to check your dipstick level regularly.


Where is the drain plug located?

Look under the oil pan at the bottom of the engine. The drain plug is a large nut. Reaching your oil drain plug is not easy. You’ll have to either crawl under your car to reach it. Secondly, you can jack up the car.

What happens if there is too much oil in a lawn mower?

Oil does many benefits to the mower. For a mower to work efficiently, it needs lubrication which is provided by the oil. The oil also prevents overheating when the mower is in use. Excess of everything is bad, so too much oil can harm the motor of the mower. The lawn mower can start leaking, too, if there is too much oil. The leaking can damage other parts of the mower.

How do I know if my lawnmower has a blown head gasket?

There are some symptoms of a bad gasket. The dropping out of a mower, oil leak and mower not getting started are the signs of a bad gasket. 

Can I use car oil for the lawnmower?

Yes, you can use car oil for a lawnmower. But it comes with a condition. The oil must be of high quality. One of the most commonly used types of high-quality motor oil on the market is SAE 30. It can be successfully employed for both cars as well as lawn mowers.


Draining oil from a mower depends on what kind of mower you are using. If you own a push mower, you can begin by propping the mower deck up so that the spark plug is facing up. After this, place the oil-safe container under the mower. Unscrew the oil plug counter-clockwise with the help of the oil plug counter. Keep unscrewing until oil can escape—lastly, empty oil from the mower into an oil-safe container. The container could be an oil drain pan.
