What Is Diesel Exhaust Fluid?
Diesel Exhaust Fluid is an essential emissions control solution for Selective Catalytic Reduction systems used in modern diesel engines. DEF reduces nitrogen oxide emissions by converting them into harmless nitrogen and water vapor.
Using quality DEF helps fleets achieve:
- Cleaner tailpipe emissions
- Improved engine performance
- Better fuel efficiency
- Compliance with EPA emissions standards
