What is a Friction Modifier Additive?

A friction modifier additive is an oil-soluble chemical that is used to help lubricate oils for internal combustion transmissions and engines. They reduce friction, which helps to boost fuel economy. Additionally, they help to prevent metal scoring, lessen engine noise and wear, and lessen the chances of micropits occurring in metal surfaces when they are used in industrial gear lubricants. Learn where friction modifier additives (and the modifiers they are used in) are used below.

What are Friction Modifiers Used In?

The friction modifier additives (and the modifiers they are in) are often used in gasoline engine oils. Specifically, they are added to the fluids that are used in power steering, shock absorbers, metalworking applications, tractor hydraulic systems, and in manual and automatic transmissions. As part of the fluids in the automatic transmissions, the friction modifiers use band and clutch engagements in order to control the torque.

How Do Friction Modifiers Work?

Friction modifiers work by creating a smooth film in order to reduce the sliding and rolling friction in the various parts of the automobile or other machine. It is very important that the right amount of friction modifier is in the liquid; in most cases, it makes up just a very small amount of the overall liquid in the transmission or other system. Other liquids are also present, including antiwear agents, which normally increase the amount of friction.

Therefore, to have the proper hydration and the easiest, smoothest movement of the vehicle, it is essential that all of these liquids have the proper balance or ratio so that there is not too much friction, nor too little friction.
