AdBlue®

AdBlue® is used in diesel vehicles equipped with Selective Catalytic Reduction (SCR) systems. When injected into the exhaust, it helps convert harmful nitrogen oxides (NOx) into harmless nitrogen and water vapor.

NOx is one of the major contributors to air pollution, acid rain, and smog.
By drastically cutting NOx emissions, AdBlue® enables vehicles to meet stringent Euro 6 and other global emission standards, making them far more eco-friendly.
This directly supports governments’ and companies’ efforts to reduce their carbon footprint and improve sustainability.

Environment

Reducing NOx emissions isn’t just about the environment; it’s also about public health.

NOx gases are harmful when inhaled, leading to respiratory problems, asthma, cardiovascular diseases, and even premature death in severe pollution zones.
AdBlue® helps protect communities, particularly urban populations who are most exposed to diesel exhaust, by lowering these hazardous emissions.
Cleaner air means fewer hospital admissions and overall improvements in quality of life.

Health

AdBlue® plays a key role in ensuring modern diesel engines can deliver both power and compliance.

Engines can maintain higher performance without being restricted by emission-limiting compromises.
It prevents engine derating or warning-light issues that occur if emission standards are breached.
Vehicles equipped with AdBlue® systems generally enjoy a longer engine life, as the SCR process reduces the strain on internal engine components.
Fleet operators also benefit from legal compliance, avoiding heavy fines for non-compliance with emission regulations.

Without SCR and AdBlue®, engines would have to run at lower combustion temperatures or with altered fuel-air ratios to reduce NOx — which often means worse fuel economy.
With AdBlue® handling the emissions post-combustion, engines can be optimized for maximum fuel efficiency and performance.
This translates into cost savings for drivers and fleet operators over time.

Vehicle Performance & Fuel Efficiency

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
