Motor oil performs several important functions in a lawn mower. It lubricates the moving parts, which helps them run more smoothly and prevents them from wearing out prematurely. Motor oil also helps to cool the engine by transferring heat away from the engine components. So, what type of motor oil is the best for your yard machine lawn mower?

The answer depends on the model of lawn mower you own. For example, if you have a Yard Machine 12A-BH09900 riding mower, you should use 10W-30 motor oil. If you have a Yard Machine 12A-BH13200 push mower, you should use SAE 30 motor oil. Be sure to consult your owner’s manual for the specific type of oil required for your model of Yard Machine lawn mower. 

Recommended Oil Types for Yard Machine Lawn Mower:

The type of oil you use in your yard machines is important for the performance and lifespan of the equipment. Here are some recommended oil types for different machines:

For a push or self-propelled lawn mower, use a standard SAE 30 oil. This will be sufficient for most mowers and will provide adequate protection against wear and tear.

If you have a riding mower, you will need to use a heavier weight oil, such as SAE 40 or 50. This will help to protect the moving parts from excessive wear.

When to Change the Oil in Yard Machine Lawn Mower?

How often you need to change the oil depends on the type of oil used, how often the mower is used, and the condition of the environment where it’s used. In general, however, most people should change the oil in their Yard Machine lawn mower every 25 hours of use or every 3 months, whichever comes first.

It’s also important to make sure that you use the right type of oil in your Yard Machine lawn mower. If you’re not sure which type of oil to use, check your owner’s manual or contact Yard Machine customer service. Using the wrong type of oil can cause damage to your lawn mower and may void your warranty.
