“AdBlue® is the registered trademark name for an Aqueous Urea Solution (AUS 32) or Diesel Exhaust Fluid (DEF). It’s a non-toxic, odourless and colourless liquid consisting of 32.5% high-purity urea and 67.5% deionised water. It is not a fuel additive, but a separate fluid used in the exhaust stage of diesel engine systems.”
“AdBlue® is required for modern diesel vehicles (typically those manufactured since around 2006, especially commercial vehicles over 7.5 tonnes) that use Selective Catalytic Reduction (SCR) technology. It is essential for meeting strict Euro 4, 5 and 6 emission standards by reducing harmful emissions.”
“AdBlue® is non-toxic and safe to handle with basic precautions. Avoid contact with skin or eyes, as it may cause mild irritation. You must ensure you clean any spills immediately to prevent crystallisation or corrosion on surfaces.”
