Diesel Exhaust Fluid for On- and Off-Road Vehicles and Equipment If your diesel fleet includes vehicles that have Selective Catalytic Reduction (SCR) systems – and since 2010 virtually all heavy duty trucks and many pickups and SUVs do – then you need Diesel Exhaust Fluid (DEF). DEF is a vital part of the SCR system. It is a solution of urea and de-ionized water that breaks down diesel engines’ dangerous NOx emissions into harmless nitrogen and water. DEF is sold in convenient drums and totes that make it easy for you to keep your fleet’s DEF tanks full.
