Engine oil is a lubricant used in internal combustion engines to reduce friction, wear, and heat. It is composed of base oils and additives, and its properties and performance can vary significantly depending on the type of engine, operating conditions, and desired performance characteristics.
The main difference between engine oils lies in their viscosity, which is a measure of the oil’s resistance to flow. Higher viscosity oils are thicker and provide better protection against wear, while lower viscosity oils are thinner and flow more easily, improving fuel economy. Other important factors to consider when choosing an engine oil include the oil’s detergent and dispersant properties, which help to keep the engine clean, and its anti-wear and anti-oxidant properties, which help to protect the engine from damage.
