Can I Use 5w20 Instead Of 5w30?

Whether 5w20 motor oil can be used in a lawn mower instead of 5w30 is common among owners. To answer this question, it is important to understand the differences between the two types of motor oil and the implications of using one over the other.

The “W” in a motor oil’s designation is “winter.” In this case, the first number, 5, indicates the oil’s viscosity at cold temperatures. The higher the number, the thicker the oil will be at cold temperatures and the slower it will flow. The second number, 20 or 30, indicates the oil’s viscosity at hot temperatures. The higher the number, the thicker the oil will be at hot temperatures and the slower it will flow.

Since 5w20 has a lower viscosity at cold temperatures than 5w30, it is a lighter-weight oil typically used in cars, while 5w30 is a heavier-weight oil typically used in lawn mowers. Using 5w20 instead of 5w30 could lead to increased friction in the engine, which could cause wear and tear. In addition, 5w20 has a lower viscosity at hot temperatures, which means it could break down faster in a lawn mower’s engine, leading to a shorter oil life.

Therefore, using 5w20 motor oil in a lawn mower is not recommended. The lighter-weight oil is designed for use in cars, and using it in a lawn mower could lead to increased wear and tear and shorter oil life. Instead, it is best to stick with the manufacturer’s recommended 5w30 motor oil for your lawn mower.

Can I Use 5w20 In The Pressure Washer?

Using 5W20 motor oil in a lawn mower is possible, but it is important to consider the type of oil used and its make and model.
