How to choose the grade and viscosity of lubricating oil
The importance of engine oil for cars is self-evident. Without engine oil, the car's engine will suffer serious damage, making it difficult for the car to move. Oil not only bears the heavy responsibility of lubrication, but also has functions such as cooling, cleaning, vibration reduction, and sealing. At present, the oil grades on the market are complex and often make car owners unsure how to choose. In fact, there are only two main indicators of oil.

Analysis and prevention of lubricating oil performance degradation
Engine lubricating oil (also known as engine oil) circulates in the engine, reducing friction and wear on the dynamic mating surface, carrying away friction heat and wear products, and playing a role in cooling, purifying, preventing oxidation and corrosion, and sealing the friction surface. The engine has strict requirements for the performance of lubricating oil, and as a lubricating oil used in the engine, it needs to have the following properties.
