You cannot have a healthy engine unless you pour the right type of oil into it.
It’s important to know what type of oil is best for your lawnmower to give your engine only what it wants. Make the correct purchase by choosing the right type of oil that we’ll tell you about here.
Types of Lawn Mower Oil
1. 2-cycle oil
Also known as a popular small engine synthetic oil, it’s the best mower oil for small engines. However, you can’t use this oil alone but have to mix it with an equal amount of fuel to fulfill the needs of the engine.
Since they don’t have a lubrication system, mixing fuel doesn’t affect its viscosity. They also work well in cold temperatures.

Sae-30 oils fill nearly every requirement of the engine and do a great job in lubricating the engine.
4. SAE-530 Synthetic
You probably have heard about small engine synthetic oil; it’s no other than SAE-530 Synthetic oil.
If your lawnmower engine asks for increased oil consumption and you can’t afford to buy an expensive lawn mower oil, this one should be your go-to option.
Not only will it fulfill your engine needs but also help in starting your lawnmower in cold seasons.
Factors to Consider When Buying the Best Lawn Mower Oil
There’s no way you can use a 2-cycle oil in a 4-cycle engine or vice versa, as it may cause an explosion in your lawnmower engine. However, there are many other things to consider when buying a commercial lawn mower oil which you’ll read below.
To put it simply, viscosity is the thickness of your lawnmower oil which has a direct impact on its flow.
The less viscous the oil will be, the better it will be to pour it into the engine. According to the variation in weather, the oil gains or loses viscosity.
The oil should not be very viscous, or else it may only lubricate the forward-facing part of the engine but not the small corners inside.
Similarly, a very diluted oil might reach those smaller areas but fail to stay there for effective lubrication. That’s why to choose a lawn mower oil that suits your region’s temperature and needs.
The quantity of your lawnmower oil decides whether it was a worthy purchase or not. The best rule of thumb is to choose a lawn mower oil bottle that has the right amount of oil in it.
Depending on your commercial lawn mower’s oil needs, pour only the amount of oil it needs and keep the rest for the next oil change.
If you change the oil once in a blue moon, then it’s better to go with small bottles and fewer ounces as you can’t store the oil for a longer time.
3. Oil Capacity
Considering the oil capacity of your lawnmower is also important to note when buying a lawnmower oil. Not all lawnmowers have the same oil capacity.
Simple walk-behinds and push mowers require less oil whimsy to vary from 16-18 ounces.
While riding mowers with heavy and complex engines can work well with 18 to 64 ounces as they have to mow larger yards in tough conditions.
Therefore, read your lawnmower’s user manual or ask the brand manufacturer to know the correct oil quantity needed for your commercial lawnmower.
Removing oil from your lawnmower is not rocket science if you follow the right steps to avoid oil splashes or any other mess.
Things you need to change the oil of your lawnmower:
Pan or container to store the drained oil
1. A rough cloth
2. Right-sized wrench
3. The right type of engine oil
4. Right-sized funnel
5. Siphon (optional)
Now that you know the correct way to pour out the old oil from your lawnmower, it’s time to add the new one and keep the engine healthy.
Follow these steps to easily add to your lawnmower engine without making any mess.
1. Gently open the oil dipstick of your mower to check the level of oil in your lawnmower. Just add new oil when your lawnmower really needs it.
2. If the oil level is low or empty, then pour the new oil directly by using a funnel that helps in avoiding oil spillage during pouring.
3. After filling the oil to the required quantity, close the dipstick as you had opened it.
4. Run the lawnmower for a few seconds so that all the oil is well distributed around the engine.
Step by Step Guide To Changing The Oil Of Your Lawnmower
- Take your lawnmower to a dry grass; it shouldn’t be your lawn as the used oil can affect your grass growth.
- Start the mower for a few minutes to warm its engine before the oil drains. This step helps the particles in the oil to float to the top of the engine and get drained easily with the oil.
- Let the mower cool before you start changing its oil. Wear gloves, disconnect the spark plug and take a siphon pump in your hands.
- Slightly tilt the mower deck and place the pan under it to avoid any spillage when the old oil is drained.
- Turn the socket wrench and turn it in a counterclockwise direction to drain all the oil. Once the oil has drained completely, close the drain plug by twisting the wrench in a clockwise direction.
