Diesel Exhaust Fluid (DEF) FAQ Diesel Exhaust Fluid(DEF) - what is it?
Diesel Exhaust Fluid (DEF) is 32.5% solution of high purity urea in demineralized water that is used with the Selective Catalytic Reduction system (SCR) to reduce emissions of nitrogen oxides (NOx) from the exhaust systems of diesel vehicles in the USA. DEF is a clear, non-hazardous liquid. It is not a fuel, nor a fuel additive and needs to be filled into a dedicated DEF tank which is on your diesel vehicle. It is replenished in a similar way to refueling diesel. Should you spill Diesel Exhaust Fluid (DEF) on your hands, simply wash it off with water.

DEF- How much do I need?
Average consumption for Diesel Exhaust Fluid is generally 2% per gallon of diesel fluid, so you will need to tank much less for DEF than you do for diesel fuel. 2.5 gallons of Air 1 diesel Exhaust Fluid will yield over 350 miles of travel.

How much does Diesel Exhaust Fluid cost?
Diesel Exhaust Fluid cost depends on the volume of your usage and the Diesel Exhaust Fluid package size that you order.

How do I store Diesel Exhaust Fluid?
Diesel Exhaust Fluid needs to be protected from extreme temperatures. DEF's freezing point is at 12 degrees Fahrenheit (-11 Celsius). When DEF thaws, the product will retain its initial quality and vehicles will remain operational throughout the Diesel Exhaust Fluid tank thawing process. DEF should be stored in a sealed package and in a well-ventilated area.

Why should I choose Selective Catalytic Reduction (SCR) with Diesel Exhaust Fluid (DEF) over other technologies?

Diesel Exhaust Fluid (DEF) combined with Selective Catalytic Reduction (SCR) offers you a fuel-efficient solution, with lower CO2 emissons than competitive solutions to adhere to the EPA Clean Air Act. Most North American truck manufacturers offer SCR equipped models to meet these regulations. SCR is a proven technology to reduce nitrogen oxide that brings diesel vehicles and fleet owners a payback with low maintenance and greater fuel economy.
