The main purpose of lubricating oil additives is to improve the original properties of base oils or to impart new properties to them. The composition of lubricating oil is: base oil 70-95%, additives 5-30%, and lubricating oil. The deeper the refining degree of the base oil, the better its performance, the lighter its color, and the higher its cost.
Common additives used in internal combustion engine oils include: detergents and dispersants, antioxidants and corrosion inhibitors, metal passivators, viscosity index improvers, pour point depressants, antifoaming agents, and demulsifiers, etc.

Common additives in industrial oils include: antioxidants and corrosion inhibitors, anti-wear agents, oiliness agents, antioxidants, metal passivators, viscosity index improvers, rust inhibitors, pour point depressants, antifoaming agents, and demulsifiers, etc. Because most additives used in industrial oils are lighter in color, and the base oils used are mostly deeply refined base oils, industrial oils are usually also lighter in color. Therefore, the quality of an oil cannot be judged solely by its color.
