If you’re interested in the science, the AdBlue mixture is made from urea (the stuff you find in urine) and is injected in tiny quantities into the car’s exhaust gases, where it rapidly breaks down mono-nitrogen oxides in the fumes. This helps to reduce the environmental damage caused by diesel fumes and keeps the air cleaner – which is good for us all. In particular, it cuts NOx pollution and particulate emissions.

NOx is present in diesel vehicles and is one of the major issues for atmospheric pollution. Adblue helps to reduce NOx and is environmentally safe. The AdBlue solution is made up of 32.5% urea and 67.5% de-ionised water. The urea in AdBlue is made by heating up synthetic ammonia and carbon dioxide. The urea is then added to the de-ionised water to create AdBlue. You may be asking ‘what’s AdBlue and why do I need it?” AdBlue is a special liquid that’s sprayed into diesel car exhausts to reduce the amount of harmful gases released into the environment by diesel engines. Adblue decomposes into ammonia and then into carbon dioxide. At present, most diesel cars are equipped with SCR technology and they arrive with separate Adblue tanks for this purpose.You will get a warning from your vehicle’s dashboard when the Adblue is running low. Be sure to act immediately for your vehicle to perform in the right manner. Before we discuss AdBlue filling stations, and the benefits they can bring for fuel card holders, let’s take a look at some key points regarding AdBlue and what it’s used for. Ensure to store Adblue at the right temperate. You cannot store Adblue in extreme heat or extreme cold. The normal temperature to store Adblue must be between 0 to 30 degrees Celsius. We often get asked ‘how much does AdBlue cost?’ However, it isn’t always a simple answer. The amount of AdBlue you want and in what form you require it, like a can, drum or in bulk, for example, can all affect the overall cost of AdBlue.

Thankfully, topping up the AdBlue reservoir is easy and cheap. Our Halfords AdBlue 10l includes all the fluid you need and comes with a handy pouring spout to make refilling a doddle.

What happens if my vehicle runs out of AdBlue?

AdBlue is charged by the litre, however, if you’re a UK business requiring high quantities of AdBlue, you may have to pay for more than just the AdBlue itself. This is because you will also have to pay for a safe storage solution for your AdBlue, alongside the pumps and specialist equipment that are required to dispense it.
