Do not think selecting the oil for your push mower is the end of the job, it’s just the beginning. You have to change and add oil regularly. You can go a long way with those simple maintenance and get the best result out of it.

In this article, I’ve discussed elaborately about what kind of oil for push mower will be the best of its use. So, without further ado, let’s start the 5 minutes reading.

Types of Oil for Lawn Mower?

Engine oil comes in different grades which indicates how will they act at different temperatures. Commonly lawnmower has a four-stroke engine that requires gasoline. 10w30 is suitable for most of the mowers. But there are also some kinds of oil which you should consider based on your temperature.

  • SAE 30: It is a single-grade oil, which means it is thicker than many lower grades oil. It is most commonly used in small engines. SAE30 is suitable for the warm temperature.
  • SAE 10W-30: This oil is good for cold-weather starting. It provides cleaning power which keeps the engine like new. But its oil consumption can be high.
  • Synthetic SAE 5W-30: It is a multigrade oil. Suitable for all kinds of weather and ensure less oil consumption. As it has fewer additives you will find lesser oxidization and vaporization in this oil.
  • SAE 5W-30: You can trust this one at a very low temperature. It makes the engine parts more resistant to rust which is perfect for the job a lawn mower does.
  • Vanguard 15W-50: Suitable for commercial and continuous use as it has a longer life span and reduced oil consumption. You can use it at a temperature between 20°F to 130°F.

How to Choose the Best Oil for Your Push Lawn Mower?

The good thing is you do not need to pick any special oil for your push mower. Any oil that is made for a car or truck is suitable for a four-stroke engine. Just make sure you are picking the best quality among the oils.

You can ask Do all push mowers use the same oil? Well, no. If you owned a two-stroke engine then you can use any motor oil made for air-cooled engines that is suitable for you.

If you live in an extremely cold area just make sure you are using a thinner viscosity multi-grade motor oil. Thin-oil can circulate better in the engine in cold weather than thick oil.

Whatever oil you choose, make sure it is of good quality. Or at least it has SF, SG, SH, or SJ rating.

Is Synthetic Oil Good for Lawn Mower?

Synthetic oil is certainly a good choice to push lawnmowers. If you are someone, confused about the relation between temperature and oil then it is the best pick for you. If you pick synthetic oil, there is not much of thinking of what kind of oil for push mower you should have used.

Synthetic oil does not tend to get thick or thin when the temperature changes. It can increase the lifecycle of a small engine as well. Synthetic oil also protects the engine better than other oils available as it offers better viscosity.

The best part is, you do not need to changes the oil between the intervals. But considering the dirty job a lawn mower does, we recommend changing it at the beginning of the season.

The only thing which is not suitable in the case of synthetic oil is its high price side. But if budget is not your problem, it is worth the money.

When to Change or Add Oil in Lawn Mower?

There are two ways you can change or add oil to a lawn mower. Use whichever method is convenient for you. But remember to drain the oil when the engine is warm. This allows the oil to suspend any internal debris within the oil.

To begin, first, run the engine minimum of 15 minutes and turn off the engine. Disconnect the spark plug and drain the gasoline from the engine by using any of the following methods.

Dipstick Tube

In this method, you have to tip the engine and drain the oil through the dipstick tube. First, remove the dipstick and tip the engine to the right side. The correct side is determined when the spark plug is up and the dipstick is closest to the ground. Place a drain pan on the floor and lean the engine so that the dipstick tube is on the pan. Now drain the oil through the dipstick tube.

Grain Plug

Not all push lawn mowers have a drain plug. The drain plug comes in several types and each type needs a different tool to open. See the manufacturer guide to determine where the drain plug is located and which type it is. Generally, it is located under the mower. Now, after you have found out the drain plug, place a drain pan under the deck and remove the drain plug. The oil will pour into the grain pan.

What Happens When You Add Too Much Oil?

While changing or adding oil make sure you put the exact amount. Otherwise, there can be several problems you may face.

When you put more oil than require there can be trouble starting the lawn mower. The engine cannot handle when it’s too much oil. There can be also white or gray smoke from the engine. Moreover, it decreases the mower’s overall performance. If you see any of this happen, drain the oil and add the required amount of oil for best performance.
