How Does DEF Help Me Comply With EPA Air Emission Standards?
The EPA began the National Clean Diesel Program in 1990 to set lower emission standards for diesel engines and further reduce air pollution. An important program goal was to produce lower sulfur content diesel so that more sensitive and efficient exhaust treatment systems could be designed.
Engineers developed selective catalytic reduction technology in response to the lower emission standards and it is now the best available diesel exhaust treatment method. SCR systems use DEF in the SCR catalyst to break down nitrogen oxide, or NOx, the main pollutant in diesel exhaust. DEF is composed of a carefully proportioned mix of a pure urea solution and deionized water. High quality DEF is important for vehicle maintenance so look for American Petroleum Institute certification to assure that DEF you use meets strict manufacturing standards.
Where Do I Find DEF?
Demand for DEF has increased dramatically since 2010 with public acceptance of the SCR/DEF diesel exhaust technology and more businesses replacing their aged diesel trucks.
Use of DEF doubled between 2011 and 2012 and continues at a 25 percent growth rate. You can purchase DEF in 1 or 2.5 gallon containers at large retail or auto supply stores, in drums or totes from fleet suppliers, or from the pump at major truck stops. The cost for DEF ranges from about 2 to 5 dollars per gallon; highest cost is containerized from stores and least cost is in bulk containers. Buying from the pump costs less than from stores and more than bulk but without the need for delivery or bulk storage.
What Are The Benefits Of Purchasing DEF At The Pump?
DEF availability is increasing as more pump locations are installed at major truck stops and diesel fueling locations. Some benefits of purchasing DEF at pump locations include:
- Convenience of filling or topping off the DEF tank at the same time you buy diesel fuel,
- Pay less at the pump versus buying DEF in smaller containers,
- No up-selling by retail merchants when buying DEF in small containers,
- Stable pump prices over the past two years, and
- Fewer stops to purchase DEF and no time and cost for management and storage of bulk DEF.
