Understanding Engine Oil Basics
Engine oil plays a crucial role in the smooth operation and longevity of your lawn mower. It acts as a lubricant, reducing friction between moving parts and preventing wear and tear. Oil also helps cool the engine, cleanses internal components, and seals gaps to prevent leaks.
Types of Engine Oil
There are two main types of engine oil: mineral oil and synthetic oil.
Mineral Oil
Mineral oil is extracted from crude oil and is the most common type of engine oil. It’s generally less expensive than synthetic oil but offers lower performance in terms of viscosity stability and protection against wear.
Synthetic Oil
Synthetic oil is manufactured in a laboratory using chemically engineered molecules. This process creates a superior oil with better viscosity stability, higher heat resistance, and superior performance in extreme temperatures. Synthetic oil is generally recommended for high-performance engines or machines operating in demanding conditions.
Viscosity: The Thickness Factor
Viscosity refers to the thickness of the oil. It’s a crucial factor in selecting the right engine oil as it influences how well the oil lubricates moving parts and circulates throughout the engine.
Viscosity Grade: SAE (Society of Automotive Engineers)
The Society of Automotive Engineers (SAE) system uses a numerical code to indicate the viscosity of engine oil. The first number represents the oil’s viscosity at low temperatures, while the second number indicates viscosity at high temperatures. For example, SAE 5W-30 oil is thinner at cold temperatures (5W) and thicker at high temperatures (30).
