DEF Diesel Exhaust Fluid PRICE LIST 

Diesel Exhaust Fluid (DEF) is a non-toxic, high purity solution comprised of 32.5% urea and 67.5% de-ionized water. Using this fluid in diesel-powered vehicles, such as trucks, buses, and tractors, helps to reduce the amount of nitrogen oxides (NOx) emitted into the air by 90%.

It is not a fuel additive and must be filled into the dedicated Diesel Exhaust Fluid tank on your diesel vehicle. A new set of gauges will be located on your vehicle’s dashboard, much like the diesel gauge, to let you know when your truck needs refilling. Refilling is similar to refueling diesel and can be done at all major truck stops across North America.

Diesel Exhaust Fluid is produced to an international standard (ISO 22241). To meet 2010 EPA Diesel Emission Standards to reduce the amount of NOx emitted by diesel engines, several engine manufactures employed Selective Catalytic Reduction (SCR) as an after-treatment technology combined with Exhaust Gas Recirculation (EGR).

The combination of SCR and DEF reduces particulate matter emissions by breaking down NOx into harmless nitrogen and water molecules. With the use of DEF, 2.6 million tons of smog-causing NOx emissions will be reduced yearly.
