When To Change your Lawn Mower Oil
The lifespan of oil in a small lawn mower or a hitch performance engine is very different from its lifespan underground. Repeated heating and cooling of your mower oil basically reduces its useful lifespan. The useful lifespan of mowers varies from one type to another; for small engines, this is around 50 hours of operation, although some range from 25 hours to 100 hours. If you’re using a new lawn mower engine, you’ll be required to change the oil after the first five hours of operation.
In addition, it is essential for you to check the oil every time you use it. Some rather harsh conditions such as high temperature, wet grass, heavy dust, and rough terrains, may affect the frequency of required oil changes, and you may be required to change it more frequently. Here are telltale signs of when to change the lawn mower oil:
After running your mower for a few minutes, take out the dipstick, and check the oil level. Then wipe it with a white paper. If it looks dirty or has some particles in it, then it’s time for an oil change.
● Hour Meter:
Riding lawn mowers and tractors often come with an hour meter. Simply follow the oil change schedule that comes with the hour meter of your lawn mower.
● Time used:
Most push mowers and some walk-behind mowers don’t come with hour meters, however, a rough estimate will do. If your lawn mower runs for four hours every week, then 50 hours should be about three months. So you know when to change your mower.
● Annual maintenance:
At the end of the mowing season, it is essential to carry out a general maintenance task on your lawn mower. While cleaning, servicing, or sharpening the blades, don’t forget to change the oil. This will keep it ready for the next mowing season.
Tools Required for Oil Change

- Short pieces of 2″ wood or any object for raising the mower off the ground
How to Change Your Lawn Mower Oil
Lawnmowers may have small engines, but they also require oil to function properly. Usually, the oil in your lawnmower equipment needs to be changed from time to time, ranging from 30 to 50 weeks depending on how long you’ve had and use the mower. Basic tools needed for changing the oil include a drain pan or any container for the old oil, funnel, rags, and hand tools. You may also decide to use an oil extractor as this can save time and mess. When changing your lawn mower oil, it is critical that you maintain some safety instructions to prevent any accidents or mishaps. Always wear disposable gloves, keep the floor sheltered with a plastic cover to prevent spillage, never change oil indoor to prevent inhalation of chemicals, and avoid changing oil near a flammable source. Below are the steps for changing oil:
Step 1. Warm up the engine:
First, warm up the engine to get the oil moving and kick up any debris so you can get it out. Do this for about 10 to 15 minutes before turning off the engine.
Step 2. Disconnect the spark plugs:
Disconnect the spark plug wire and remove it out of the way.
Step 3. Lift the lawn mower:
You can decide to tip the mower to have easy access to the drain plug: this is to prevent fuel spillage. Simply remove the fuel tank, empty it, or seal the fuel cap with a plastic bag. However, if you have an oil extractor, simply skip this stage. Remember to clean around the dipstick port and the neck to prevent contamination. Then extract the oil and skip to Step 6.
Step 4. Locate the drain plug:
If you do not have an oil extractor, locate the drain plug and clean around it. For push mowers, you’ll find the drain plug under the mower deck, usually caked with grass clippings. Clean it to prevent contamination and wear.
Step 5. Drain the oil:
Next, remove the drain plug and carefully drain the old oil into your drain container or pan. Once you’ve drained it completely, clean and reinstall the drain plug. Then move the drain pan under the filter, and replace it.
Step 6. Refill with new oil:
Refill the tank with new oil. If your mower doesn’t have a pouring nozzle, use the funnel, pouring little oil at a time, and constantly checking the dipstick. Make sure you don’t overfill the engine.
Step 7: Test the engine:
Once done, remove the funnel and reconnect the spark plugs. Then run the engine for a couple of minutes before shutting it off. Carefully inspect the equipment for leaks, and if everything is fine, then you should be good to go.
Once you make it a habit of changing your lawn mower oil regularly, you’re simply taking care of your precious investment which will pay back with years of reliable service.
How to Keep Your Lawn Mower Running
Here are basic procedures that will help you maintain your lawn mower for a long time.
● User manual:
Always read the user manual – you should take some time out to study the user manual that comes with your mower. This is the best way to use your mower correctly and avoid unnecessary issues.
● Drain the gas at the end of the season:
Remember to drain the gas at the end of every mowing season- Typically, old gasoline left for a long time will become gummy or viscous and will harm your mower engine. Old gas is usually the reason why your mower won’t work at the beginning of a new season. Always drain the old gas and use a fresh one for a new season.
● Check the oil level:
You should make a habit of monitoring the oil level in your unit regularly. It is also important to check for any floating debris in it. Once your oil becomes dark brown or black, then it is probably too old or contaminated and would need replacement.
● Check the air filter:
If the air filter is dirty, it won’t burn gasoline efficiently. It is a wise idea to change the air filter once a year to prevent inefficiency. The procedure is actually not too expensive so you don’t need to worry about the cost.
● Change the spark plugs
The spark plug should also be replaced as it is inexpensive. Being a crucial part of any mower’s system, it should be changed at least once a year.
● Clean out the mower’s undercarriage
Your mowers undercarriage can easily get caked with wet grass, and this can clog the discharge chute of your mower. So you should scrape grass clippings off and clean the undercarriage from time to time.
● Sharpen the blades
If your mower blades are dull, you won’t be able to make precise cuts. Instead, it will rip and tear the grass, making your lawn unhealthy and less appealing. So you should sharpen your mower blades regularly. If you can’t do it yourself, visit a mower repair shop for help.
● Employ professional tuning services
You should also consider going to a professional to carry out necessary diagnostic tests and tuning-up on your mower.
When using a lawn mower, expect two or more moving parts in the engine to come into contact with each other. To keep these parts running smoothly, lubrication is necessary, and can only be possible with fresh and good oil. Change the oil in your new lawn mower after the first 5 hours of use and after every 25 to 50 hours of operation also. We hope this has been helpful. Good luck!
