What kind of oil does a lawn mower take?

Lawnmowers typically use either 10W-30 or SAE 30 oil. 10W-30 is a multi-grade oil that can be used in both hot and cold weather. It has a viscosity rating of 10W when cold, which means it is easier to start the engine in colder weather. It also has a viscosity rating of 30 when hot, which means it provides enough lubrication to the engine in warmer temperatures. SAE 30 oil is a single-grade oil that is recommended for use in warmer temperatures.

It is important to note that not all lawnmowers use the same type of oil. Some lawn mowers may require a different type of oil, so it is important to check the owner’s manual to see what kind of oil is recommended for your specific lawn mower.

Different types of lawnmowers

There are a few different types of lawnmowers. Here’s a breakdown of what kind of oil each type uses:

Gas-Powered Mowers: Most gas-powered lawn mowers use gasoline to power the engine. Some models use premium gasoline, while others use regular unleaded. Many people think that using premium gasoline will improve the performance of their lawn mowers, but this isn’t always the case. All-purpose gas is typically fine for most lawnmowers.

Electric Mowers: An electric lawn mower uses an electric motor to power the blades. They usually have two charging ports – one in the handle and one on the side. You can charge them using a standard household outlet, or by using an adapter that plugs into your car’s cigarette lighter socket.

String Trimmers: A string trimmer is a smaller version of a gas or electric lawn mower. They typically have a shorter blade than either of those two types of Lawn Mowers and they’re meant for trimming rather than cutting grass.

Hover Mowers: A hover mower is a type of lawn mower that uses relatively little fuel and has a lower emissions rating than traditional mowers. They work by cutting the grass using blades that are suspended above the ground. This style of lawn mower is often preferred by people with limited space to store a larger lawnmower.

How to choose the right oil for your lawn mower

When choosing the right oil for your lawn mower, it’s important to consider the type of engine your machine uses and what type of cutting you want to achieve. Here are some tips on how to choose the right oil:

Lawnmowers with petrol or diesel engines require different oils. Petrol-powered lawnmowers need a light oil that helps prevent the build-up of dirt and fuel in the engine, while diesel lawnmowers need a heavier oil that is resistant to burning and provides longer engine life.

For standard cutters, synthetic oil is usually sufficient. However, for mulching or chopping modes, a high-quality blended gasoline/oil blend is recommended. These types of mowers use less fuel and generate less polluting emissions, so they’re perfect for environmentally conscious users.

To ensure long-lasting performance, change your lawn mower’s oil every 4 months or 10 000 miles whichever comes first.

What to do if your lawn mower doesn’t have an oil filter

If your lawn mower doesn’t have an oil filter, you’ll need to add some oil to the machine. You can use any type of oil, but bearing oil is a good idea because it’s resistant to corrosion. Add enough oil to cover the bottom of the engine. Run the lawn mower until it stops, then tip the machine backward so the oil can drain out.

If you have a gas-powered lawn mower, it’s important to check the oil level often to prevent engine trouble. Follow these steps to check the oil in your lawn mower:

  • Remove the spark plug cap and unscrew the plug. Look for metal bits around the base of the plug. If there are metal bits, your lawn mower is overdue for an oil change.
  • Pour a little bit of oil into the mower’s engine and replace the plug. Turn the key to on, wait a few seconds for the engine to start, then stop it and check the oil level again. Add more oil if needed.
  • Leave the engine running while you do your other chores so that any accumulated gas can flow out of the system and away from possible problems.


Choosing the right type of oil for your lawn mower is important for maintaining the health and longevity of lawn mowers. Using the wrong type of oil can lead to poor engine performance, decreased fuel efficiency, and environmental damage. It is important to refer to your owner’s manual to determine what type of oil is recommended for your specific lawn mower. By changing your oil regularly and following proper maintenance procedures, you can keep your lawn mower running smoothly for years to come.
