AdBlue® is a registered trademark of Verband der Automobilindustrie e.V. (VDA).
AdBlue® is a pure colourless, urea solution produced to exact specification from the organic compound Urea and demineralised water. AdBlue® is injected in measured quantities to your vehicle’s exhaust gases and, with the help of the vehicle’s catalytic converter changes the toxic exhaust gas. AdBlue® reacts with the exhaust gases from the engine and helps to convert oxides of nitrogen emissions into harmless gas and water vapour. The use of AdBlue® is one technology adopted by truck manufacturers to help meet the latest regulations on diesel engine emissions.
AdBlue® can be purchased at the pump or in packaged bottles at selected United sites.
If your vehicle is equipped with Selective Catalytic Reduction technology, it will require diesel such as AdBlue® to be operational.
