How to correctly replace engine oil and filters, prevent engine failures, and repair methods, etc
The engine is one of the core components of a car, commonly referred to as the 'heart', and is also one of the most easily damaged components. Therefore, maintaining the engine is very important. This article will explore how to replace oil and filters, prevent engine failures, and repair methods.

What is the effect of water resistance in lubricating grease?
Lubricating grease with good water resistance ensures that it can still provide good lubrication in the presence of water, while lubricating grease with poor water resistance is not suitable for areas in contact with water. For example, the continuous casting operation process in the steel rolling industry is characterized by a large amount of cooling water directly spraying on the hot steel billet. At this time, not only does a large amount of water enter the bearings, but also a large amount of water vapor is generated and exists on the surface of the bearings. Lubricating grease is always in a high temperature and high humidity state. If the water resistance of the grease is not good, it is easy to be washed and lost, losing its lubricity.

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.
High temperature lubricating grease becomes the future industry growth point!
With the continuous improvement of China's industrialization level and the increasing use of advanced equipment, the working temperature of many lubrication parts is getting higher, and the requirements for the high-temperature resistance of lubricating grease are also constantly increasing. The commonly used lubricating grease in China is a metal soap based grease based on mineral oil, with a usage temperature not exceeding 120 ℃. Studying high-temperature lubricating grease is of great significance for meeting the high-temperature lubrication requirements of certain equipment.

Standard for lubricants used in construction machinery
Construction machinery is often in a high-speed and high load working state, and the function of engine oil is to transport lubricating oil to the friction surfaces of various moving parts, in order to achieve lubrication, sealing, cleaning, cooling, hydraulic, buffering, and rust prevention functions.
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.
