What is the function of lubricating oil

Lubricating oil is used in various machinery to reduce friction and protect machinery and various processed parts. It mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. The lubricating oil of automobiles needs to be replaced regularly .

Engine oil can be lubricated by the engine, auxiliary cooling, anti-corrosion and anti-rust. The engine oil is mainly composed of two parts: base oil and additives. The base oil determines the basic properties of the lubricating oil. The internal parts of the engine are running at high speed when the engine is working, and the temperature of the internal parts of the engine can reach several hundred degrees Celsius. Using lubricating oil can reduce the wear of the internal parts of the engine, prolong the service life of these parts, and improve the harsh working environment. Most of the lubricating oils used in automobiles are semi-synthetic oils, which keep the working conditions of automobile engines in a relatively stable position.
