How often should you change your lawn mower oil?

How often should I check or change my oil?
You should check your oil every time you use your equipment. Oil leaks can start without warning and are often overlooked. In some cases, the engine will lose enough oil to cause permanent damage to the engine. This is why it is important to check the oil frequently and add oil when necessary.

How often you change the oil depends on the type of equipment you are using and how often you use it. As a general rule, oil should be changed every 20-25 hours in push mowers and every 40-50 hours in riding mowers. Most push mowers and similar equipment will need an oil change at least 2 times per season, while riding mowers may only need one oil change per season. No matter what equipment you have, you should change the oil whenever it begins to look dirty.
