AdBlue is a high quality urea solution that is easy to use

AdBlue is the registered trademark for AUS32, or Aqueous Urea Solution 32.5% that is used with the Selective Catalytic Reduction system (SCR) to reduce emissions of oxides of nitrogen from the exhaust of UK diesel vehicles. AdBlue is a 32.5% solution of high-purity urea in de-mineralized water that is clear, non-toxic and safe to handle. It is non explosive, non flammable nor harmful to the environment. AdBlue is classified under the minimum risk category of transportable fluids. It is not a fuel, nor a fuel additive and needs to be used in a dedicated tank in your heavy-duty vehicle. It is replenished in a similar way to refuelling diesel. Should you spill AdBlue on your hands, simply wash it off with water.

How much AdBlue do I need?

Average consumption of AdBlue in UK vehicles is generally 5% of diesel use, so you will need to tank much less for AdBlue then you do for diesel. You will use about 5 liters of AdBlue to every 100 liters of diesel.

How should I store AdBlue

AdBlue can be stored for 1 year if this is done in a correct manner ie away from direct sunlight. It needs to be protected from too warm or too cold temperatures. Its freezing point is at -11 degrees Celsius. When it thaws, the product will retain its initial quality. It should be stored in a sealed package and in a well ventilated storage area.
