    AI Overview
    AdBlue (often referred to as AUS 32 or DEF) is a high-purity, colorless aqueous urea solution used in diesel engines equipped with Selective Catalytic Reduction (SCR) technology to reduce harmful nitrogen oxide (NOx) emissions. 
    Composition and Properties 
    • Formula: It consists of 32.5% high-purity synthetic urea and 67.5% demineralized water.
    • Standardization: It meets the ISO 22241 standard.
    • Appearance: A colorless, non-toxic liquid with a slight ammonia smell.
    • Freezing Point: Freezes at approximately -11.5°C (11.3°F). 
    Function in Vehicles 
    • SCR Technology: AdBlue is sprayed into the exhaust system, where it breaks down NOx into harmless nitrogen and water.
    • Compatibility: Essential for most modern diesel vehicles (Euro IV and later, Euro 5/6) to meet environmental standards.
    • Storage: It is stored in a separate, dedicated tank (often with a blue cap), not in the fuel tank.
    • Consumption: Average consumption is about 3-5% of diesel fuel consumption. 
    Usage and Handling 
    • Not a Fuel Additive: AdBlue should never be mixed with diesel fuel.
    • Corrosive: While safe to handle, it can be corrosive to some metals and should be rinsed off with water if spilled on the vehicle.
    • Availability: Commonly sold in bottles, jerry cans, and specialized pumps at service stations. 
    AdBlue is a registered trademark of the German Association of the Automobile Industry (VDA).
