AdBlue® is a high-purity, non-toxic urea-based solution used in modern diesel engines to reduce harmful emissions. It works as part of a system called Selective Catalytic Reduction (SCR), helping convert nitrogen oxide (NOx) — a major pollutant — into harmless nitrogen and water vapor.

Made from 32.5% urea and 67.5% deionised water, AdBlue® is not a fuel additive and is stored in a separate tank in your vehicle. It’s essential for keeping diesel engines compliant with strict environmental regulations and contributes to a cleaner, greener Australia.

Southern Blue proudly manufactures certified, high-quality AdBlue® to meet ISO standards, ensuring your engine runs efficiently while reducing its environmental impact
