Types of Oil for Lawn Mower

As we have mentioned, there are different types of lawn mowers that require different types of engine oil. Some people also use motor oils for this purpose, which work in a similar fashion. These motor engine oils are designed to work in smaller engines as well, so you can use them too. But we would suggest that you use those motor oils only when you don’t have access to dedicated mower oils.
You need to make the right choice based on the climate in which you live. We have listed some of the most frequently-used types of oil from different regions and continents.
lawn mower oil type

SAE 30

There are SAE 30 small engine oils that are designed for warmer climates. They are by far the most frequently used motor oil for small engines, and are installed in machines like lawn mowers.

SAE 10W 30

These oils are made for climates where temperature varies. While this oil has a tendency to increase the overall oil consumption, it is good in cold starting.

SAE 5W 30 Synthetic

These oils cover the discrepancy of increased oil consumption, and also stays effective in cold starting.

SAE 5W 30 Semi-Synthetic

These oils are better suited for extremely cold temperatures.

Vanguard 15W 30

If you are looking for a wide temperature range, then you need to go for Vanguard 15W 30. This oil is excellent for consistent use, and you can use it for commercial purposes.
When you are going for mower oil, choose top-quality oil with classified detergency. This includes the likes of For Service SI, SH, SG, SF, or anything higher. And don’t go for any of those special additives. Synthetic types are suitable in all temperatures. Using this oil will not alter the intervals for oil change.
Oil capacity of different lawn mowers may also vary from one to another. If we’re talking about walk-behind mowers, then the oil capacity will range typically from 16 ounces to 18 ounces. But in the case of riding mowers, the oil capacity ranges from 48 ounces to 64 ounces. You need to change your mower’s engine oil annually or every 100 hours, whichever comes first.

Oil for Lawn Mower - Buyer’s Guide & FAQ

There are some important features that you need to keep in mind when choosing motor oil for your mower. First of all, its type needs to be considered because different engines have different requirements. Then you need to see how much of it is needed so that you can purchase an appropriate amount, making sure nothing gets wasted or left over. Here are some of the important points that you must consider before buying the right engine oil for your lawn mower.

Oil types for lawn mowers

There are different types of engine oils for lawn mowers. These include SAE 30W, SAE 5W 30, SAE 10W 30, and Vanguard W50. We have described all these types earlier in this post for your convenience. so refer to that part of text for better understanding. Choosing the right kind of oil is necessary because it is designed according to the age and type of an engine. For example, you can use SAE 30W instead of 10W 30, but SAE 30W is made for older engines while 10W 30 is for modern engines. So you will immediately feel the difference. Apart from that, viscosity is very important.


Viscosity is the thickness of a fluid and its ability to flow. If an engine oil is thick, then it will get even thicker in cold temperatures. Whereas in hot temperature, oils become thinner. This variation in fluidity according to temperature is called viscosity, and it influences any oil’s ability to lubricate everything inside an engine and reach all the smallest of regions. Thicker or more viscous oils will have a difficult time reaching those small areas, but if they make it they will stay there for longer periods and keep the frictions low. More diluted oils will easily get into those small areas, but won’t stay there as long. So you will have to decide according to the climate of where you live.


You need to purchase the right amount of oil so that nothing gets left behind when you are done using the bottle. For instance, if the engine oil capacity of your lawn mower is 48 ounces, and you buy 2 bottles each of 40 ounces then you will have to store 32 ounces until your next oil change. Then, you will again have to buy another bottle that will also leave a lot of oil to spare, and then you’ll have to store that as well.

Is there any difference between a 4-cycle oil and a regular one?

There is no difference between these two types of oils. The 2-stroke or 2-cycle engine oil is formulated in a way that you can mix it with gasoline. There is no separate area for the oil to go. On the other hand, 4-stroke or 4-cycle motor oil is your regular engine oil that you use in your car.

Can I use my motor vehicle engine oil in my lawn mower?

If you have a big lawn mower then you can go for your automobile oil and use it in your mower. But if your mower is smaller, then you cannot do so because it runs on smaller engine oils.

The best time to change oil in a lawn mower?

The answer to this question heavily relies on the specs that are specified by the manufacturer of the lawn mowers. Some of them are designed in a way where you don’t need to change their oil at all. You must consult the owner’s manual of your mower to find the right answer. It is better to change the pool at least once a season of use, or after about 60 hours of mowing (whichever comes first).

How to check the lawn mower oil level

You have to follow the following steps to check the oil level in your lawn mower.

  • Just apply a slight pressure (clockwise) on the dipstick cap to twist it open.
  • Now remove that cap and, using a rag, clean it for clear reading.
  • Place the dipstick cap (cleaned) back and match the groove top with the cap’s teeth.
  • Now, with some pressure, turn the cap (counterclockwise) to lock it.
  • Do the 1st step again and twist the cap clockwise with a slight pressure.
  • Remove that cap again and see the oil level.
  • If the level is low, fill it in ounces and close the cap.
  • Give it some time and check the level again by repeating all the above steps.
