What is blue def used for?

Blue DEF (Diesel Exhaust Fluid) is a high-quality solution that is added to diesel vehicles equipped with Selective Catalytic Reduction (SCR) systems to reduce harmful emissions. It is a mixture of 32.5% high-purity urea and 67.5% deionized water, which is injected into the exhaust stream of diesel vehicles to convert harmful nitrogen oxide (NOx) emissions into harmless nitrogen and water vapor.

Blue DEF is essential for the effective operation of SCR systems in diesel vehicles, as it helps to break down NOx emissions and meet stringent emissions regulations. It is a clear liquid that is non-toxic, non-hazardous, and safe to handle. It is widely available at gas stations, truck stops, and automotive retailers, making it convenient for diesel vehicle owners to refill their tanks when necessary.

Using Blue DEF can help improve fuel efficiency, reduce maintenance costs, and reduce harmful emissions, making it an important component for diesel vehicles to operate cleanly and efficiently.
