Tips on Choosing the Right Lawn Mower Oil

Type of Oil

Finding the right oil for your lawnmower is critical. There are hundreds of varietals and brands that compete on the market. However, it all starts with understanding the type of oil that is suitable for your lawn mower’s engine.

The type of oil recommended for your particular mower is largely dependent on manufacturer recommendations. But generally, it is recommended to use oils that are labeled SAE 30. This uses less power than other oils and performs well under warm temperatures which your lawnmower needs. With the right oil for your mower, you should get the most performance out of it while burning less fuel.

Using the wrong oil can result in poor performance, harsh handling, and increased wear and tear on engines and drive chains. That’s why it pays to know which type of oil is best to use on your lawnmower.

Engine oil vs Motor oil

If you haven’t noticed already, the list of products mentioned above comprises both engine oils and motor oils. But what are the differences between the two? Should you pick one oil over the other and is it important to do so? Let’s find out.

While some lawnmowers use the same motor oil as your car, others require commercial-grade oil. Commercial-grade motor oils are developed specifically for high-performance gas and diesel engines. They burn at higher temperatures, cool quicker after running, and resist oxidation. These features make it ideal for heavy-duty engines that are often subject to extreme conditions.

However, the viscosity of motor oils is much higher which can clog up the bearings of your push mower and cause irreversible damage to your engine. This is why it is suitable only for heavy-duty engines doing heavy-duty work.

On the other hand, engine oils are much friendlier to lawnmower engines than motor oils. Small engine oil is designed for high-temperature environments, and it protects the engine from overheating. In addition, it reduces friction and improves fuel economy.

But if you have a larger and heavy-duty lawn mower engine, engine oils will burn faster which can lead to too much waste and cost over time since you will have to change the oil often. A thick viscosity motor oil is a more practical choice for this.


Before using any type of oil in a lawnmower, it is important to first read the user manual for that particular machine to make sure the oil is compatible with your engine.

Lawnmower manufacturers usually recommend a specific type of oil to be used in the mowers. Also, some brands manufacture specifically developed oils for their product so purchasing the same brand of oil as your engine might be the best choice.

Alternatively, if you choose not to, always consult your lawnmower owner’s manual for recommendations on the best oil to use in your mower.

Final Words

Lawnmower oil is an important part of the mower engine system. It keeps the engine parts moving freely and prevents overheating and other engine problems.

But choosing the right oil can be one of the most difficult parts of your new mower maintenance. When you are looking for lawn mower oil, you will want to make sure that the oil that you choose has been produced to the highest quality standards and meets safety and performance specifications.

The oil industry has grown rapidly in the past few years. But by considering the things we have talked about earlier, then you can make an educated decision as to which lawn mower oil will suit best for you.
