Diesel Exhaust Fluid (DEF)

Everything you need to know about Diesel Exhaust Fluid

What is Diesel Exhaust Fluid?

Diesel Exhaust Fluid (DEF) is an additive that is necessary to lower high levels of Nitric Oxide (NOx) to produce lower emissions. The fluid is made of a mixture of urea and deionized water, a reductant of NOx. Diesel Exhaust Fluid is a requirement for all medium and heavy duty vehicles with diesel engines made after 2010. The EPA implemented this requirement in 2007 when it changed emission requirements for all over-the-road trucks. To put it into perspective, 1 gallon of DEF is used per 1000 miles.
