When we talk about lubricants, we usually think of the lubrication and protection it provides to machinery and equipment. However, the importance of lubricant additives is often overlooked. These additives actually play a key role in the lubricant, improving its performance and providing it with additional protective features. In this article, we’ll take an in-depth look at the role, classification, and selection recommendations of lubricant additives.

The role of lubricating oil additives
Lubricating oil additives mainly have the following functions:
Improved fuel economy: Some additives can improve the fluidity of lubricants, allowing the engine to run more efficiently, thereby improving fuel economy.
Improve lubrication effect: Lubricating oil additives can reduce friction and reduce wear and tear on machinery and equipment during operation, thereby improving the operating efficiency of the equipment.
Reduce wear: By adding appropriate additives to the lubricating oil, a protective film can be formed on the metal surface, thereby reducing wear and extending the service life of the equipment.
Classification of lubricating oil additives
According to their main functions, lubricating oil additives can be divided into the following categories:
Detergent: This type of additive can remove deposits such as carbon deposits and paint films, improve the combustion efficiency of the engine, and reduce fuel consumption.
Dispersant: Dispersants can evenly disperse these deposits in the lubricating oil, prevent them from agglomerating on engine parts, and effectively protect the engine.
Anti-wear agents: Anti-wear agents can form a protective film on friction surfaces, thereby reducing wear and extending the service life of engines and transmission systems.
Preservatives: Prevent lubricating oil from being corrupted and provide anti-corrosion protection for the metal surfaces of the lubrication system.
Viscosity index improver: mainly improves the viscosity-temperature properties of the base oil so that it can maintain good viscosity under various temperature conditions.
Anti-rust agent: forms a protective film on the metal surface to prevent moisture, salt and other corrosive substances from corroding the metal.
Pour point depressant: lowers the freezing point of lubricating oil and improves low-temperature fluidity.
Antioxidants: Slow down the oxidation rate of lubricating oil and extend its service life.
Suggestions on Selection of Lubricating Oil Additives
It is very important to choose appropriate lubricant additives for different mechanical equipment and operating needs. Here are some suggestions:
Selection based on equipment type: For different types of equipment, such as automobiles, aircraft, industrial machinery, etc., targeted additives need to be selected to maximize their effects.
Selection based on operating conditions: Different operating conditions, such as high temperature, low temperature, high pressure, etc., require the selection of corresponding additives to meet the needs of the equipment.
Consider additive compatibility: When selecting an additive, make sure it is compatible with the base oil and equipment materials to avoid adverse effects.
Long-term benefit considerations: When selecting additives, long-term benefits should be considered. For example, anti-wear agents can protect the engine and extend its service life.
Brand reputation and quality assurance: Choose additives with good brand reputation and quality assurance to ensure their performance and reliability.
Conclusion
In summary, lubricant additives play an important role in improving equipment performance, protecting engines and extending service life. The correct selection of additives can not only improve the operating efficiency of the equipment and reduce maintenance costs, but also increase the service life of the equipment. Therefore, understanding and mastering the relevant knowledge of lubricating oil additives is of great significance for equipment maintenance and upkeep.
