1. Composition of lubricating oil
Lubricating oil is composed of base oil, additives and colorants. Base oil is the main component of lubricating oil, which determines the basic performance of engine oil. Additives can make up for and improve the performance of base oil and give some new performance.
2. Function of lubricating oil
Engine oil is the engine lubricating oil. The engine is the heart of the car. The engine has many metal parts that rub against each other. These parts move fast, the environment is poor, and the working temperature can reach 400 to 600 degrees. Under such bad conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong their service life.
3. Classification of base oil
1. Mineral base oil
Processed and extracted from crude oil through a series of physical and chemical methods.
2. Synthetic technology base oil
It is obtained by carefully mixing mineral base oil and synthetic base oil. Its performance is higher than that of mineral base oil but lower than that of fully synthetic base oil.
3. Fully synthetic base oil
It is obtained through complex physical and chemical processes, such as molecular structure reforming and synthesis. The production cost is more expensive and the performance is more superior.
