AdBlue, also known as AST Blue or Diesel Exhaust Fluid, is a crucial component for modern diesel vehicles equipped with Selective Catalytic Reduction (SCR) systems. This non-toxic, urea-based solution is injected into the exhaust stream, converting harmful nitrogen oxides into harmless nitrogen and water vapour. By using AdBlue, diesel engines can meet stringent emissions standards while maintaining optimal performance. This 20-litre container provides a convenient way to replenish your vehicle's AdBlue supply, ensuring compliance with environmental regulations and promoting cleaner air quality. Regularly topping up AdBlue is essential for maintaining your vehicle's emissions control system and avoiding potential penalties or operational issues. Stay on top of your AdBlue levels and contribute to a greener, more sustainable future with this essential diesel exhaust fluid.
