During the use of lubricating oil, a series of chemical changes such as oxidation, polymerization, alkylation, decomposition, etc. occur due to oxygen in the air, by-products of fuel combustion, high temperature, and catalytic effects of engine parts, forming substances such as coke, gum, asphalt, etc., which cause a series of adverse consequences to the machinery using the lubricating oil, such as engine bearing corrosion, piston ring adhesion, paint film and sludge formation, and increased oil viscosity, seriously affecting the normal operation of the engine. In order to solve the problem of oxidation hazards of various lubricants under different working conditions and increase their antioxidant or thermal oxidation stability, it is necessary to use various types and amounts of antioxidants. Lubricating oil antioxidants can greatly delay the rate of oxidation and deterioration of lubricating oil, and their role in lubricating oil is self-evident.

However, during the use of lubricating oil, additives will degrade at a certain rate due to usage conditions. When the additive level reaches the critical value, the performance of the lubricating oil will sharply decrease, losing its lubricating effect and causing machine malfunctions. By measuring the content of antioxidants in lubricating oil, people can predict the remaining life of lubricating oil and prevent excessive use of lubricating oil.
