Introduction to Engine Oils
Before diving into the specifics of using automotive oil in lawn mowers, it’s essential to understand the basics of engine oils. Engine oils, also known as motor oils, are designed to lubricate the moving parts of an engine, protecting them from wear and tear. They also help to cool the engine, prevent corrosion, and clean the engine by carrying away dirt and debris. The primary function of engine oil is to reduce friction between moving parts, which in turn, reduces heat buildup and prevents engine damage.
Types of Engine Oils
There are various types of engine oils available, each designed for specific applications. The most common types of engine oils are:
Automotive oils, which are designed for use in passenger vehicles and trucks. These oils are formulated to meet the demands of high-speed engines and are typically designed to operate in a wide range of temperatures.
Marine oils, which are designed for use in boats and other marine vessels. These oils are formulated to withstand the harsh conditions of saltwater and high-humidity environments.
Aviation oils, which are designed for use in aircraft engines. These oils are formulated to meet the unique demands of aircraft engines, which operate at high altitudes and in extreme temperatures.
Small engine oils, which are designed for use in small engines, such as those found in lawn mowers, generators, and chain saws. These oils are formulated to meet the specific demands of small engines, which typically operate at lower speeds and temperatures than automotive engines.
Viscosity and Additives
Two critical factors that distinguish different types of engine oils are viscosity and additives. Viscosity refers to the oil’s thickness and flowability, with thinner oils being more suitable for cold weather and thicker oils being more suitable for hot weather. Additives, on the other hand, are chemicals that are added to the oil to enhance its performance. Common additives include detergents, dispersants, and friction modifiers.
