You've heard of it... You think you might need it... But, you're not sure you understand it. Confused? You're not alone.

There is a lot of conflicting information in the marketplace about just what DEF is, what it does and who is mandated to be using it to meet Federal guidelines.

DEF is a mixture of high purity synthetic urea and deionized water that is used in Selective Catalytic Reduction (SCR) systems on diesel engines. It is injected into the exhaust stream via a controlled dosing module to react with and neutralize the NOx molecules and convert them to harmless nitrogen and water.

The Environmental Protection Agency requires all 2010 and newer on road diesel vehicles to be equipped with SCR technology which requires the use of DEF. Off road vehicles will be phased in next year.
