Valvoline Premium Blue Diesel Exhaust Fluid enables on-highway diesel engines to meet the EPA’s near-zero NOx (Nitrogen Oxide) emissions levels required for 2010 and later. The Environmental Protection Agency requires all 2010 and later on-highway diesel engines to meet NOx (Nitrogen Oxide) emission standards. In order to meet these lower standards, most engine manufacturers are using Selective Catalytic Reduction (SCR) exhaust after-treatment. These systems mix Diesel Exhaust Fluid (DEF) with exhaust gas and use a catalytic converter to change the NOx emissions into Nitrogen and water.
- Compatible with all on and off highway SCR systems
- API and AdBlue certified
- Meets ISO 22241 specification
- Manufactured and packaged using only dedicated equipment to ensure the product is pure and contaminant free
