What is DEF or Diesel Exhaust Fluid ?

Diesel Exhaust Fluid (DEF) is a non-hazardous solution, which is 32.5% urea and 67.5% de-ionized water. DEF is sprayed into the exhaust stream of diesel vehicles to break down dangerous NOx emissions into harmless nitrogen and water. This system is called Selective Catalytic Reduction (SCR) and can be found on 2010 and later model year trucks and many diesel pickups and SUVs. DEF is not a fuel additive and never comes into contact with diesel. It is stored in a separate tank, typically with a blue filler cap.

Why Do I Need Diesel Exhaust Fluid  ?

Selective Catalytic Reduction (SCR) is the technology of choice for most leading truck and engine manufacturers to meet the new regulations for diesel exhaust emissions.

With SCR engines, drivers must maintain adequate levels of DEF in a truck’s DEF tank at all times.

Before a truck’s DEF tank runs empty, the driver is alerted through dashboard displays. If a truck is allowed to run out of DEF:

• the engine power is reduced
• a solid red warning will be displayed
• vehicle speed will be limited until the DEF tank is refilled
