- Heavy usage: If you mow your lawn regularly, or use your mower for other tasks like mulching or trimming, you may need to change the oil more often.
Always consult your owner’s manual for specific recommendations. This will provide the most accurate information for your particular model and ensure you’re following the manufacturer’s guidelines.
Why is Regular Oil Change Necessary?
Oil plays a vital role in keeping your lawn mower engine running smoothly. Here’s why changing the oil regularly is crucial:
1. Lubrication
Oil acts as a lubricant, reducing friction between moving parts within the engine. This prevents excessive wear and tear, prolonging the life of your mower. Over time, oil breaks down and loses its lubricating properties, increasing friction and causing damage.
2. Cooling
Oil helps to dissipate heat generated by the engine, preventing it from overheating. When oil becomes contaminated or breaks down, it loses its cooling efficiency, putting your engine at risk.
3. Cleaning
Oil acts as a cleaning agent, removing dirt, debris, and metal particles that accumulate during operation. Over time, this buildup can clog the oil passages and impede engine performance. Regular oil changes help flush out these contaminants and keep your engine running smoothly.
4. Corrosion Protection
Oil forms a protective layer on metal surfaces, preventing rust and corrosion. As oil degrades, its corrosion protection weakens, making your engine susceptible to damage.
