Def
DIESEL EXHAUST FLUID
DEF, or Diesel Exhaust Fluid, is a high purity solution of urea in water (32.5%) used to chemically reduce NOx emissions from trucks and buses powered by diesel engines. D.E.F. is contained in a separate tank and is sprayed into the exhaust gases.
Eljay Oil carries DEF in bulk, totes, drums, and cases.
WHY USE DEF?
Diesel Exhaust Fluid (DEF) is a new product required by many heavy-duty trucks, pickups, SUVs, and vans delivered after January 2010. DEF is used to destroy harmful emissions in the exhaust and meet the EPA’s latest strict environmental standards.
DEF is non-hazardous and consists of 67.5% de-ionized water and 32.5% urea, and is used in combination with Selective Catalytic Reduction (SCR) technology. It is sprayed into the exhaust and combines with a catalyst to break down NOx (a harmful pollutant) into nitrogen and water.
In January 2010 emissions legislation came into force which requires diesel vehicles to significantly reduce harmful emissions of NOx and particulate matter. A good way to meet these standards is to use SCR and DEF.
SCR technology offers many benefits, most importantly great fuel efficiency. On top of this, owners of SCR vehicles will enjoy greater reliability and a longer oil change interval, all of which adds up to impressive savings over the life of the vehicle.
In 2011 some agricultural, construction and forestry equipment was required to meet more stringent emissions standards and a number of manufacturers use SCR and DEF.

Diesel Exhaust Fluid (DEF) is a relatively new product required by many heavy-duty trucks, pickups, SUVs, and vans delivered after January 2010. DEF is used to destroy harmful emissions in the exhaust and meet the EPA’s latest strict environmental standards. In addition to protecting the environment, one of the most significant benefits of using DEF is the greater fuel efficiency.
