AdBlue is a premium aqueous urea solution (32.5% ultra-pure urea + deionized water), a dedicated emissions reduction agent for diesel vehicles with SCR systems, meeting Euro VI, China VI and other global strict emission standards. Colorless, non-toxic and non-flammable, it�s injected into exhaust to convert toxic NOₓ into harmless nitrogen and water vapor, cutting over 90% of such emissions without affecting engine performance. Stored in a vehicle�s dedicated blue tank, it has a low consumption (3-5% of diesel use) and is widely refillable at gas stations and auto service centers. A must for eco-friendly modern diesel automotive operation, with on-board alerts for low levels to ensure compliance.
