Buying and evaluation criteria for lawn mower oils

When looking for the right lawn mower oil, you will first come across many different products. With so many products to choose from, it can be difficult to find the right lawn mower oil. However, there are some criteria that you should use as a guide:

The following criteria should make it easier for you to find the right lawn mower oil for your lawn mower.

Suitability of the lawn mower oil

Since there are different types of lawn mowers, it is important to find the right oil for them. When buying lawn mower oil, you should know what type of lawn mower you have. Generally, there is a distinction between a 2-stroke and a 4-stroke.

If you do not know which type of engine is installed in your lawn mower, you should check the manual. This is a crucial decision when buying lawnmower oil.

Here is what you should consider:

Type Description
2-stroke In a 2-stroke engine, the lawn mower oil is usually mixed with the fuel. However, there are also models with an extra oil tank that automatically mixes the lawnmower oil with the fuel. In this way, the lawn mower oil is also burned in the 2-stroke engine and is used for the correct purpose.
4-stroke Most modern lawn mowers are built with a 4-stroke engine. Unlike the 2-stroke engine, the lawnmower oil is not burnt here, but is used to lubricate the important engine parts.

Once you have answered this question, you can look for a high quality lawn mower oil.


A quality lawn mower oil is important to ensure a long life of the lawn mower. The performance of the lawn mower also depends on the quality of the lawn mower oil.

When buying lawn mower oil, you should choose certified quality oils. Look for certifications such as SF, SG, SH, SJ. These usually designate high-quality lawn mower oil.

Quality lawn mower oil ensures cleanliness in the engine area. A high level of additives guarantees good lubrication, which in turn has an effect on the service life.

A quality lawn mower oil is rewarded with a long service life of the lawn mower. Therefore, it is better to invest a little more money.

Package volume

There is no standard package volume for lawn mower oil. Therefore, you should always pay attention to the price-performance ratio when buying.

High-quality lawn mower oil is usually offered in smaller packaging volumes at an average price. On the other hand, poorer quality lawn mower oil is offered in large packaging volumes at a favourable price.

Some examples of common packaging volumes:

  • Lawn mower oil 0.5 litre
  • Lawnmower oil 1 litre
  • Lawnmower oil 1.5 litre
  • Lawnmower oil 3 litres

As you can see here, lawn mower oil comes in a variety of different pack sizes. So you should decide for yourself how much you need and whether a smaller pack volume is sufficient.

Shelf life

In general, lawn mower oil has a relatively long shelf life. It is important to store the lawn mower oil correctly and to keep it in a sealed container. Unopened, the best-before date is given as between 3 and 5 years.

However, the lawn mower oil should not be stored for a lifetime, as this risks the important additives being dissolved out. Therefore, it would be advisable to buy a smaller package volume so that this is not risked.

Guide: Questions to ask yourself before buying lawn mower oil

Before buying lawn mower oil, there are several factors you should consider. Therefore, we have compiled a collection of the most important questions here, which should clarify all open questions.

What is special about lawn mower oil and what advantages does it offer?

Lawn mower oil is important for any fuel-powered lawn mower and contributes to its durability. Quality lawn mower oil keeps the engine area clean. Lawn mower oil is essential for the use of a fuel-powered lawn mower.

Not using lawn mower oil risks damaging the lawn mower and making it unusable. Thus, lawn mower oil is an important ingredient when using a lawn mower.

What types of lawn mower oil are there?

As there are different types of engines, there are also different types of lawn mower oils. A distinction can be made between lawn mower oil for 2-stroke or 4-stroke engines.

When differentiating between lawn mower oil, it is important to consider whether the lawn mower is only used in spring and summer or all year round.

If you have a 2-stroke lawn mower, a conventional 2-stroke lawn mower oil is sufficient. For 4-stroke engines, there are the following different types:

Lawn mower oil SAE 30

This type of lawn mower oil has a viscosity of 30. SAE stands for Society of Automotive Engineers and assesses the viscosity of the oil.

  • Best suited for 4-stroke engines
  • High viscosity
  • Not suitable for cold season use

This 4-stroke engine oil is suitable for use in the warmer months of the year. It should not be used in the winter months. The price is lower compared to all-season oil.

Lawn Mower Oil 10w30

This type of lawnmower oil can also be used in winter. This is indicated by the number 10, which stands for the flow properties in cold weather. The smaller the number, the better it is for cold weather.

  • Suitable for 4-stroke engines
  • Suitable for winter use
  • Mostly not used in winter
  • Higher price

Before buying, you should consider whether you will also use the lawn mower in winter. This can affect the price of the lawn mower oil.

Who is lawn mower oil suitable for?

Lawn mower oil is suitable for anyone who cares about their lawn mower. Since the purchase of a lawn mower is often associated with a lot of money, it pays to maintain it carefully. Therefore, lawn mower oil is one of the most important components of maintenance, along with cleaning.

Therefore, lawn mower oil should be a component in every garage with a lawn mower. Due to large packaging volumes, lawn mower oil is also ideal for gardening businesses or home maintenance companies. The price can be lower due to a large package volume.

How often should lawn mower oil be changed?

In order to contribute to a long service life of the lawn mower, regular maintenance is essential. Therefore, the lawn mower oil should also be changed. Only refilling the oil is not sufficient for careful maintenance; the oil should be changed completely at regular intervals.

It is better to check the oil level once more than too little.

Heat causes the lawn mower oil to lose its lubricating capacity. Dirt particles can also form.

Therefore, the lawn mower oil of a 4-stroke engine should be changed once a year. Spring is the best time to do this, before the first operation.

For heavily used lawn mowers, i.e. more than 25 hours a year, this is not sufficient. The lawnmower oil deteriorates noticeably, especially under difficult conditions when mowing the lawn. This means that the lawn mower oil should be changed every 25 hours of use.

With a newly purchased lawn mower, the lawn mower oil should already be changed after 5 to 6 hours. This prolongs the service life.

The situation is different with 2-stroke engines. Since the lawn mower oil is mixed directly with the fuel, there is no need to change the lawn mower oil.

How do I change the oil in a lawn mower?

Too much or too little lawn mower oil in the lawn mower is not good. Therefore, it should be checked frequently and topped up when necessary. There are a few steps to follow when refilling.

To check the oil level, a dipstick is usually integrated in every lawn mower. To measure, the dipstick is cleaned with a paper towel and then inserted into the oil container.

The oil level should not be below the minimum limit, but also not above the maximum limit. Therefore, fill with a funnel until just before the maximum limit.

If you want to change the oil in your lawn mower, the engine should already have been warmed up. After the engine has warmed up, the spark plug cap should be pulled out to be on the safe side.

Then find and open the oil drain plug and pour the old lawn mower oil into a container.

For the inexperienced, this is often a messy business. Therefore, it is a good idea to use an oil extractor. With this device, the lawn mower oil can be easily extracted. After you have filled the lawn mower oil, you can refill it with new oil.

How much does lawn mower oil cost?

The price range for lawn mower oil is not very wide. The price usually differs in package volume and quality. Special promotions usually reduce the price of lawn mower oil.
