Function: Engine oil, also known as engine lubricant, with a density of approximately 0.91*10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is often referred to as the "lifeblood" of a car. 2. Classification: Engine oils on the market can be divided into mineral oils and synthetic oils based on their base oil. Synthetic oils are further categorized into full synthetic and semi-synthetic. Lubricant base oils are mainly classified into mineral base oils and synthetic base oils. Mineral base oils are widely used and account for a large proportion (about 95% or more), but certain applications require products formulated with synthetic base oils.
