    AI Overview
    High-grade AdBlue (Diesel Exhaust Fluid) is a non-toxic, high-purity
    32.5
    %
     synthetic urea solution used to reduce
    NOxcap N cap O sub x
    𝑁𝑂𝑥
     emissions in diesel engines. To guarantee system compatibility and prevent expensive catalyst damage, ensure your fluid strictly complies with ISO 22241 quality standards. 
    AdBlue Quality & Standards 
    Using certified high-grade AdBlue is critical for keeping your Selective Catalytic Reduction (SCR) system operating correctly. 
    • Composition:
      32.5
      %
       high-purity urea and
      67.5
      %
       deionized water.
    • Certification: Look for packaging or dispensers that explicitly state ISO 22241 compliance (or DIN 70070).
    • Licensing: Purchase from registered VDA (Verband der Automobilindustrie) or API (American Petroleum Institute) certified licensees.
    • Reliability: Major manufacturers like Yara International and BASF utilize strictly controlled synthetic prill-free manufacturing to prevent particulate contamination. 
    Sourcing & Purchasing 
    You can easily source certified AdBlue through authorized auto parts retailers, specialized fuel distributors, or directly at the pump. 
    • Automotive Retailers: Convenient pre-packaged bottles (usually 0.5 to 2.5 gallons) are available through ECS Tuning and BimmerWorld for passenger vehicles.
    • Local Auto Zones: For immediate local needs in the Los Angeles area, check inventory and pick up brands meeting ISO standards at your nearest AutoZone or O'Reilly Auto Parts store.
    • Bulk Refills: If you operate a heavy-duty fleet, commercial distributors offer bulk deliveries or larger dispensing units. 
    Handling & Storage 
    Proper storage is vital to preserving the purity of your high-grade AdBlue. 
    • Shelf Life: AdBlue lasts for about 12 to 18 months if stored correctly.
    • Temperature Control: Keep the solution stored between
      11∘F11 raised to the composed with power F
      11∘F
       and
      86∘F86 raised to the composed with power F
      86∘F
       (
      -11.5∘Cnegative 11.5 raised to the composed with power C
      −11.5∘C
       to
      30∘C30 raised to the composed with power C
      30∘C
      ). Extreme heat will cause it to degrade rapidly, while freezing (below
      11.5∘F11.5 raised to the composed with power F
      11.5∘F
      ) won't harm the fluid, but you must allow it to thaw completely before use.
    • Contamination Risk: The SCR system is incredibly sensitive. Never dilute the fluid with water, never add it directly to your diesel fuel tank, and always use clean, dedicated equipment when pouring to prevent debris from entering the system. 
    For a closer look at the different grades of DEF, why quality matters, and how to prevent costly breakdowns related to fluid contamination:

    Is there a different quality of AdBlue?
    There are several different types of AdBlue. These are differentiated by International Organisation for Standardisation (ISO) 22241 numbers. ISOs ensure that the AdBlue you use is effective and has been created to the proper specifications. Modern diesel cars run on ISO-22241-1, ISO-22241-2, or ISO-22241-3.Nov 15, 2024

    What is 40% DEF used for?
    Marine DEF, or AUS 40, is an aqueous high-purity urea solution at a concentration of 40% that is needed to operate converters with SCR in applications with large combustion engines. As the name implies, Marine DEF is used in many marine applications but is increasingly used in rail and other land-based applications.

    Are there two types of AdBlue?
    Are there different types? While there are different names for AdBlue®, such as Bluedef, BlueTec and so forth, all mixes should contain the same solution of 32.5% urea and 67.5% de-ionised water.
