    AI Overview
    Yes, modern diesel trucks (Euro 6 and newer) use AdBlue® (a 32.5% urea solution) to reduce harmful nitrogen oxide (NOx) emissions. It is stored in a separate tank, often with a blue cap, and injected into the exhaust stream, where it breaks down NOx into nitrogen and water. 
    This video explains how AdBlue works in your diesel engine:

    Key Aspects of AdBlue in Trucks: 
    • Function: It is not a fuel additive; it is part of the Selective Catalytic Reduction (SCR) system, which is crucial for meeting emissions standards.
    • Consumption: Generally, usage is around
      2
      %
      −6
      %
       of fuel consumption, though heavy applications may differ.
    • Refilling: It must be refilled when low, or the truck may refuse to start.
    • Storage: AdBlue is stored in a separate, dedicated tank, not in the diesel fuel tank.
    • Emulators: Some operators have used AdBlue emulators to bypass the system, though these are often illegal due to the increased pollution they cause. 
    How to Properly Use AdBlue: 
    • Locate the Cap: Find the blue filler cap (often next to the fuel cap).
    • Refill Procedures: Use reputable, ISO 22241-1-approved AdBlue. Use a nozzle or container with a proper seal to avoid spills.
    • Never Mix: Do not fill the fuel tank with AdBlue, or the engine will be severely damaged.
    • Safety: While non-toxic, it can be corrosive to metal, so wash spills with water. 
    This video demonstrates how to safely refill your AdBlue tank:

    What will happen if a truck runs out of AdBlue?
    If you run out of AdBlue, your diesel vehicle will not be able to start or continue driving for long. AdBlue is a fluid used in diesel engines to reduce harmful emissions - so, if the AdBlue tank runs dry, the system detects this and triggers a warning on your dashboard.Feb 25, 2026
