        As car ownership continues to rise in China, and the age structure of car buyers continues to decline, more and more young people have their own cars, I take you to understand some lubricants。
        A very important part of the car is the car engine, and in order to better reflect the performance of the car engine and increase the service life of the car engine, most people are gradually concerned about the lubricating oil that needs to be applied every time they maintain, so what is the lubricating oil?How to choose a good car oil?It is a difficult question that many people will ask, and I will introduce it belowLanzhou lubricating oilSome basic knowledge。
Lubricating oil is composed of base oil + additive。

        In which the base oil is divided into mineral base oil and formation base oil。Mineral base oils are immediately obtained from petroleum in response to changes in physical state, so they are less reliable from a molecular perspective。The generated base oil is obtained according to a chemical reaction, and the reliability of the generated base oil is relatively easier to use。Different lubricants from base oils are also divided into mineral lubricants, synthetic lubricants (also called fully synthetic lubricants), and semi-synthetic lubricants。Semi-synthetic lubricating oil refers to not only the mineral base oil but also the formed base oil in the base oil。In terms of the reliability of finished oil products, fully synthetic automotive lubricating oil is better than semi-synthetic automotive lubricating oil than mineral lubricating oil。

Lubricating oil

        Lubricating oilPerformance levels are generally based on specifications developed by the American Petroleum Institute (API)。Generally, we often see some signs such as APISN or APISL on gasoline drums, which is the performance level of lubricating oil。In which "S" means steam turbine generator oil, "S" after the English letter means the level of lubricating oil, the lower the English letter indicates the higher the level。
        Secondly, the indication of the lubricating oil index value is the viscosity。The general viscosity is indicated by "SAE10W40" or "SAE5W30"。SAE is the Gome Automotive Technical Engineers Association。10W40 or 5W30 is an indication of lubricating oil viscosity, the number before the English letter "W" indicates the ultra-low temperature operation of this product, the smaller the data, the higher the ultra-low temperature operation。The data after "W" indicates the cutting property of lubricating oil at high temperature. The larger the data, the higher the viscosity of the product and the thicker the product。
