Lubricant additives are chemical compounds that are added to lubricants, such as engine oil or transmission fluid, to enhance their performance and characteristics. These additives can improve the lubricant’s ability to reduce friction and wear, protect against corrosion and oxidation, and maintain its viscosity at high temperatures. Some common types of lubricant additives include friction modifiers, detergents, antioxidants, and anti-wear agents. Adding lubricant additives to your engine oil or transmission fluid can help prolong the life of your engine or transmission and improve its overall performance.
