FAQ:

Q: What is a transmission friction modifier?

A: The purpose of a friction modifier varies based on the application. In a combustion engine, the goal is to lower the amount of friction, thereby gaining fuel economy. In clutches, automatic transmissions and industrial applications, the aim is not simply to control friction in order to maximize efficiency but to reduce slippage.

Q: What is the best transmission fluid?

A: Royal Purple is the best transmission fluid if you are looking for a fluid that is pretty much compatible with any car model. It is a synthetic automatic transmission fluid that has a low coefficient of friction, a high film strength, and is more stable from oxidation.

Q: What is a limited slip friction modifier?

A: Limited-slip differentials contain clutches that automatically deliver more power to to a wheel that has traction and less to a wheel that is slipping. Friction Modifier additive eliminates noise that can occur when limited-slip mechanisms engage and disengage.

Q: How do friction modifiers work?

A: How friction modifiers work. Reducing this metal to metal friction helps engines run more efficiently. Quality gasoline, containing friction modifier additives, offer some real value. Gasoline with friction modifiers helps improve fuel economy, and when vehicles burn less fuel, they produce less emissions.
