What kind of oil should be used for a lawn mower?
2 Answers
For the engine part of a lawn mower, ordinary oil can be used. Here are the detailed contents about lawn mower oil: 1. Precautions: Do not clean the lawn mower with gasoline. To change the oil, you only need to drain the old oil from the original machine and then add new oil. It is completely unnecessary to clean with gasoline. Moreover, gasoline mixed and deposited in the engine will deteriorate the newly added oil, increase engine wear, and harm the engine. 2. Definition: Modern lawn mowers consist of a blade disc, engine, walking wheels, walking mechanism, blades, and control parts. Lawn mowers save the working time of manual weeding and reduce a large amount of human resources.
With decades of mechanical repair experience, I can tell you that choosing oil for a grass trimmer depends on the engine type. For two-stroke trimmers, you must use specialized mixed oil, such as JASO FD standard oil, blended with gasoline at a ratio of around 1:50. Never use the wrong type, or the engine will quickly fail and may emit black smoke. Four-stroke trimmers are simpler—just use SAE 30 or 10W-30 oil. SAE 30 is better for high summer temperatures, while 10W-30 is ideal for winter to prevent freezing. Always check the user manual for recommended brands—don’t cheap out with low-quality oil, as it increases carbon buildup and affects RPM. Regular oil changes are crucial—replace it every 50 hours of use to prevent engine wear. If you notice excessive oil consumption or unusual noises, inspect and repair promptly, as these issues impact machine lifespan and performance.
