What is DEF?
DEF, an acronym for Diesel Exhaust Fluid, is the trucking industry’s response to U.S. Environmental Protection Agency standards requiring all medium and heavy-duty diesel vehicles to significantly reduce engine emissions, particularly nitrous oxide as well as particulate matter. It was mandated to come into use beginning with 2010-manufactured engines.
DEF is a clear, colorless, non-hazardous liquid looking exactly like water but that has a slight odor of ammonia. It is composed of urea and deionized water. The urea component is an organic compound made up of nitrogen, hydrogen, carbon and oxygen.
