What Types of Oil Are Suitable for Lawn Mowers?
As you may have noticed in our review, there are different types of oils for lawn mowers, each typically designed to fit various engine types.
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 recommend using specialized lawn mower oil to achieve optimal performance from your equipment and maintain it in good condition throughout the year, even during the off-season.
Below, you can review some of the types of oil and the climates in which they’re used. 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 small engines, such as lawn mowers.
- SAE 10W-30 provides optimal performance in areas with varying climates and temperatures, and it excels at cold starting, although it may increase overall oil consumption.
- SAE 5W-30 synthetic oil is also suitable for cold starts and exhibits a low oil consumption level.
- SAE 5W semi-synthetic is best used for extreme cold climates.
What are the Main Features to Check for?
Some of the most essential features to consider when purchasing any oil are its viscosity and quantity.
- Viscosity is used to define the thickness of a fluid, as well as its ability to flow. For instance, if the oil has high viscosity at cold temperatures, it can become even thicker, and when heated, it can become thinner. Additionally, the variation in fluidity can influence engine lubrication – the more freely the oil can flow, the better the lubrication will be, as it can reach even the most minor parts of the engine. On the other hand, thick oils can’t get to the small parts quickly; however, once they do, they’ll keep the parts lubricated for longer. Ultimately, 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. Ensure you buy the correct amount of oil to fill the mower, avoiding both excess and insufficient oil.
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 changes. To avoid trouble, refer to the instruction manual to find the correct 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 regular task that ensures there is always enough oil for the mower to run correctly. There are some steps you need to take to check the level:
- With slight pressure, remove the dipstick cup, clean it, and then reinsert it, ensuring it is locked in place.
- Then, again, remove the cap and check the oil level.
How to Remove Old Oil From a Lawn Mower?
It’s always a good idea to remove old oil from the lawn mower, and there are specific tips & tricks you can use to do this the right way.
First, you need to find a suitable location to dispose of the old oil, and this should be far away from gardens, grass, and other vegetation to prevent any mishaps and spills. Potentially, the best place to do this is a paved area of your yard – make sure also to cover this area with paper to avoid any stains on the concrete.
Once you’ve found the location, ensure the engine is cold before starting the draining process. For added safety, wear protective gloves to avoid burns.
For the actual draining, you can use an oil drain or a siphon pump. After turning the plug on the lawn mower counterclockwise, the oil will start draining into your collection device.
When draining oil from any motor, ensure that you dispose of it in an eco-friendly manner. Never dump the oil in your garbage bin or drain; instead, there are special dealerships, centers, or gas stations that offer assistance with oil disposal.
What’s The Right Amount of Oil?
Depending on the size of your lawn mower, you can determine how much oil to use. To make this easier, we can divide the lawn mowers into walk-behind mowers, whose capacity ranges between 15 oz and 18 oz, and riding mowers that have a larger capacity, ranging between 48 oz and 64 oz.
Additionally, you can always refer to the instruction manual for the lawn mower to ensure you understand the correct size.
Adding the right amount of oil is essential because if you add too much, the engine may start emitting gray or white smoke – this means it’s time to change the oil and add the correct amount.
Excess oil can cause difficulties with starting and lower the performance of your mower, potentially ruining a well-planned Sunday morning of grass mowing.
