III. What is Diesel Exhaust Fluid?
Diesel Exhaust Fluid (DEF) is a high purity solution of urea in demineralized water (32.5%) which meets the automotive industry specifications defined by ISO 22241. A clear liquid similar in appearance to water, DEF is safe to handle by humans, pets and the environment. It is not explosive, flammable, toxic or subject to any hazardous product regulations. DEF is contained in a separate tank; a user must never fill a diesel fuel tank with DEF. DEF is consumed at roughly 3% of diesel fuel consumption, so for every 100 gallons of diesel, 3 gallons of DEF are required.
