Diesel Exhaust Fluid FAQs

Uses Diesel Exhaust Fluid (DEF), a solution of urea and primarily water to reduce NOx emissions to near zero!
Diesel Exhaust Fluid (DEF) is an automotive grade of 32.5% urea mixed with 67.5% demineralized water. It’s Non-hazardous, non-toxic, and non-flammable. DEF is used in Selective Catalytic Reduction (SCR) systems to change diesel powered bus, car, and truck NOx emissions to nitrogen and water.
DEF will be used about 2% - 3% of your diesel fuel consumption. Therefore, every time you use 100 gallons of diesel fuel you will need approximately 2 – 3 gallons of DEF.
No, there is a separate tank for the fluid. DEF should not be added to the fuel tank.
Diesel engines equipped with SCR using DEF not only meet the 2010 tailpipe standard, but they also deliver a significant fuel economy benefit.
