Small Engine Oil

Small engine oil, often referred to as four-stroke engine oil, is a specialized lubricant designed for use in small gasoline-powered engines. These engines are commonly found in lawn mowers, generators, pressure washers, and other outdoor power equipment.

Small engine oil

Small engine oil serves several important functions:


The primary function of engine oil is to lubricate the moving parts within the engine, such as the piston, crankshaft, and camshaft. This reduces friction and wear, extending the life of the engine.


Engine oil helps dissipate heat generated during engine operation, preventing overheating and damage to engine components.


Small engine oil contains detergents and additives that help remove contaminants, such as dirt and debris, from the engine. This helps keep internal engine parts clean and prevents the buildup of deposits that can impair performance.

When selecting small engine oil, it's essential to choose the appropriate viscosity grade and quality level recommended by the engine manufacturer. Viscosity refers to the oil's resistance to flow at a specific temperature, and the viscosity grade indicates the oil's thickness or consistency. Common viscosity grades for small engine oil include SAE 10W-30 and SAE 30.

Proper maintenance of small engines, including regular oil changes using the correct type of oil, is crucial for optimal performance and longevity. It's essential to follow the manufacturer's recommendations for oil change intervals and procedures to ensure the engine operates smoothly and efficiently.
