CNH Diesel Exhaust Fluid

CNH Diesel Exhaust Fluid is a non-hazardous solution that is sprayed into the exhaust stream of diesel vehicles to break down dangerous NOx emissions into harmless nitrogen and water. This Selective Catalytic Reduction (SCR) can be found on 2010 and later model year trucks and many diesel pickups and SUVs. DEF is not a fuel additive and never comes in contact with diesel.
