What is Adblue and why is it used?
Adblue is a generic name for a colourless, odourless liquid which is made from urea and mineral water (32.5% and 67.5% respectively).
Adblue is a diesel exhaust fluid used in the exhaust to lower NOx emissions at the tail pipe. This is an after combustion treatment.
NOx emissions cause and worsen emphysema, bronchitis and heart disease so the European Union are forcing manufacturers to drastically reduce this tail pipe emission (Euro 6).
What Vehicles are Fitted with Adblue?
Adblue is only applicable for diesel engines. On September 2015 the Euro 6 standard was introduced so there is a higher possibility of such a system being fitted to your vehicle if its manufacturing date was on or after September 2015.
Audi, BMW, Citroen, Ford, Mazda, Mercedes-Benz, Opel, Peugeot, Toyota & Volkswagen.

How Long Will Adblue Last? When do I Refill the Reservoir?
This all depends on distance, driving style, journey type, engine/vehicle load and environmental conditions. Please see chart below for averages for AdBlue equipped Volkswagen cars. (Source VW UK)
The vehicle will notify you when a top up is needed. It is vital you fill the Adblue tank as the vehicle will reduce performance firstly and then not allow the engine to start if the Adblue tank is empty.
How do I Refill the Reservoir? Can I do it?
Adblue is contained in a separate tank to diesel. Never mix Adblue with diesel, it is not a fuel additive.
The Adblue tank is usually found under the bonnet, in the fuel filler cap or in the spare wheel well.
Adblue is easy to fill as the container mates to the fill valve on the car ensuring a clean and easy fill. If you get Adblue on your hands or on the vehicle make sure to wash them with water immediately.
If you are unsure about the filling procedure bring the vehicle to your local Main Dealership.
