What Types of Oil For Lawn Mower Are There?

As you noticed in our review, there are different types of oils for lawn mowers and they usually fit different types of engines.

More so, you can use even motor oils to fuel up your lawn mowers, since they’re made in the same manner and can work well with smaller engines like these.

Nevertheless, to be on the safe side, we suggest using specialized lawn mower oil to get the best performance from your equipment and keep it in a good shape throughout the year, even during the idle season.

Below, you can review some of the types of oil and the climates they’re used in. This list can give you a better understanding of what to buy.

  • SAE 30 is designed for warmer climates and is one of the most commonly used motor oils for lawn mowers and other small engines.
  • SAE 10W 30 gives the best performance in places where the climate and temperature vary and it works great for cold starting, although it can increase the overall consumption of oil.
  • SAE 5W 30 synthetic oil is also good for cold start and doesn’t give a great oil consumption level.
  • SAE 5W semi-synthetic is best used for extreme cold climate.

What are the Main Features to Check for?

Some of the most important features to check when buying any type of oil are viscosity and quantity.

  • Viscosity is used to define the thickness of any flued as well as the ability to flow. For instance, if the oil is with high viscosity in cold temperatures it can get even thicker and when hot become thinner. Also, the fluidity variation can influence the engine lubrication – the more the oil can flow, the better the lubrication will be since it can reach even the smallest parts of the engine. On the other hand, thick oils can’t reach the small parts fast however, once they do, they’ll keep the parts lubricated for longer. In the end, it all comes down to the type of climate you live in.
  • Quantity is another factor to consider when purchasing fuel for your lawn mower. Make sure you purchase the needed amount to be able to fill up the mower and you don’t have any oil leftover or not enough.

When’s the Best Time to Change the Lawn Mower Oil?

This depends on the different specifications and characteristics shared by the lawn mower manufacturer. Some engines are designed in a way that doesn’t require any oil change. To save yourself from trouble, make sure you refer to the instruction manual to find the proper answer. Ideally, you can change the oil at least once every season.

How to Check Oil Level?

Checking the oil level in your mower is a task that you must do regularly to ensure there’s always enough oil for the mower to run properly. There are some steps you need to do in order to check the level:

  • With slight pressure remove the dipstick cup, clean it and then put it back in and make sure you lock it.
  • Then, again remove the cap and check the oil level.

How to Remove Old Oil From Lawn Mower?

It’s always a good idea to remove old oil from the lawn mower and there are certain tips & tricks you can use to do this the right way.

First, you need to find a good location where you want to dispose of the old oil, and this has to be far away from the garden, grass and other vegetation to avoid any mishaps and spillages. Potentially, the best place to do this is a paved area of your yard – make sure you also cover this area with papers to avoid any drops staining the concrete.

Once you’ve found the location, make sure the engine is cold before you start the draining and to be entirely safe make sure you wear protective gloves to avoid burning yourself.

For the actual draining, you can use an oil drain or a siphon pump and after turning the plug on the lawn mower counterclockwise, the oil will start draining in your collection device.

When draining oil from any type of motor, you must ensure to dispose of it in an eco-friendly manner. Never dump the oil in your garbage bin or drain; there are some special dealerships, centers, or gas stations that assist with oil disposal.

What’s The Right Amount of Oil?

Depending on the size of your lawn mower you can understand how much oil you need to use. To make this easier, we can divide the lawn mowers into walk-behind mowers whose capacity ranges between 15oz and 18oz and riding mowers that have a bigger capacity ranging between 48oz and 64 oz.

Additionally, you can always refer to the instruction manual for the lawn mower and make sure you understand the right size.

Adding the right amount of oil is important because if you add too much the engine might start exhausting gray or white smoke – this means it’s time to change the oil and add the right amount.

Excess oil can cause difficulties with starting and lower the performance of your mower – this can ruin a well-planned Sunday morning of grass mowing.
