What Is Diesel Exhaust Fluid (DEF)?

DEF is a non-toxic, colorless solution composed of 32.5% high-purity urea and 67.5% deionized water.

Injected into the exhaust stream of diesel engines equipped with Selective Catalytic Reduction (SCR) systems, DEF converts harmful nitrogen oxide (NOx) emissions into harmless nitrogen and water vapor — delivering cleaner air and compliance with EPA standards.

Benefits include:

  • Up to 5% improvement in fuel economy

  • Reduced emissions meeting 2010+ EPA mandates

  • Extended SCR system life

  • Lower maintenance costs over time
