To make lubricants adhere better to metal surfaces, friction modifiers are often used. Friction modifiers are additives that reduce friction between moving parts and help lubricants adhere better to metal surfaces. They often contain molecules with polar or polarizable groups, which allow them to bond with metal surfaces to create a smoother, more protective surface.…

With the development of industry, oil products are used more and more widely, and different oil products have different properties and uses.
