Lubricating Oil Additive Usage Ratio

Lubricating Oil Additive Usage Ratio

An ashless dispersant manufacturer explains: Lubricating oil is generally composed of base oil and additives. Compared to base oil, additives account for a smaller proportion in the formulation, generally not exceeding 25%. Although the amount used is extremely low, its role is very important. Only by appropriately adding various types and amounts of additives can a lubricant acquire its specific properties.

Domestic additives are generally divided into two categories: non-functional additives and functional additives.

Non-functional additives mainly refer to additives that improve the general properties of lubricating oils, such as high and low temperature rheology and anti-foaming properties. Examples include viscosity index improvers, pour point depressants, anti-foaming agents, and demulsifiers. The amount added is often adjusted according to the performance indicators of each batch of base oil.

Functional additives refer to additives that enhance or impart certain properties to lubricants, mainly playing a role in anti-oxidation, reducing friction, and preventing rust. Once the lubricant formulation is formed, the proportion of functional additives is determined and generally does not change. In addition, mixtures of multiple additives pre-formulated for specific oil products are generally called compound additives, or simply compound agents. Examples include compound additives for internal combustion engine oils and compound additives for hydraulic oils.
