Can You Use Car Engine Oil in a Lawn Mower?

The answer to this question is a resounding no. Car engine oil is designed for use in high-performance engines that operate at high temperatures and speeds. Lawn mower engines, on the other hand, are much smaller and operate at lower temperatures and speeds.

Why You Shouldn’t Use Car Engine Oil in a Lawn Mower

1. Wrong viscosity. Car engine oil is typically much thicker than lawn mower oil, which can cause the engine to run hotter and wear out faster.
2. Additives. Car engine oil contains additives that are not designed for use in lawn mower engines. These additives can damage the engine or cause it to run poorly.
3. Detergents. Car engine oil contains detergents that can break down the protective film on the inside of the lawn mower engine. This can lead to rust and corrosion.

What Type of Oil Should You Use in a Lawn Mower?

You should use a specifically formulated lawn mower oil. Lawn mower oil is designed to meet the specific needs of lawn mower engines. It has the correct viscosity, additives, and detergents to protect the engine and keep it running smoothly.

How Often Should You Change the Oil in a Lawn Mower?

You should change the oil in your lawn mower every 25-50 hours of operation. This will help to keep the engine clean and running smoothly.

Conclusion

Never use car engine oil in a lawn mower. It can damage the engine and shorten its lifespan. Always use a specifically formulated lawn mower oil.
