Using Diesel Exhaust Fluid (DEF) 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 a non-toxic, high purity solution comprised of 32.5% urea and 67.5% de-ionized water.
It is not a fuel additive and must be filled into the dedicated Diesel Exhaust Fluid tank on your diesel vehicle. Refilling is similar to refueling diesel and can be done at all major truck stops across North America.
DEF is produced to an international standard (ISO 22241).
Priced per 55 gallon drum, 275 gallon tote or 330 gallon tote. No minimum order to avoid shipping charges.
