AdBlue FAQs

What is AdBlue?

AdBlue is a mixture of urea and deionised water that is used in a diesel vehicle’s exhaust system to lower nitrogen oxide (NOx) emissions.

AdBlue makes it a lot easier to lower vehicle emissions so that they comply with the stricter Euro 6 emissions regulations that came into effect in 2016.

What does AdBlue do?

When mixing our AdBlue product with diesel-engine exhaust fumes, it significantly reduces the release of mono-nitrogen oxide from engines.

Reducing NOx emissions is critical as it brings diesel engine vehicles in line with Euro 6 emissions regulations. There has been a 67% decrease in nitrogen oxides released in the exhaust emissions of diesel cars since the introduction of these regulations.

There are two effective ways of getting this reduction:

  1. By a Selective Catalytic Reduction (SCR) system
  2. By an exhaust gas recirculation system

Any machinery with an SCR system requires AdBlue for effective operation; using alternative liquids, such as tap water, can cause problems with the machinery, such as limescale build-up in the catalyst.

What is AdBlue made of?

AdBlue is derived from Aqueous Urea Solution 32.5% and, as a result, is sometimes known as AUS 32. AdBlue comprises 32.5% high-purity urea and 67.5% deionised water.

In AdBlue, the urea is pure and is of a higher substance than that used in cosmetics, glue or fertilisers. The water is also demineralised, which is much cleaner than water from the tap. This helps AdBlue prevent residue build-up on the inner workings of your vehicles or other machinery.

How does AdBlue work?

Small quantities of AdBlue are combined with a vehicle’s exhaust emissions; it breaks down the harmful mono-nitrogen oxides in diesel exhausts into nitrogen and water vapour.

This technology has long been used in buses and lorries and has proven its effectiveness in these applications. It is now being used in more commercial vehicles as well as personal diesel vehicles.

What are the business benefits of using AdBlue?

The main benefits of using AdBlue are that your business emissions are reduced and your fleet is in line with Euro 6 standards.

As well as lowering the negative environmental impact of your business operations, it also helps your company gain more green accreditations and positive recognition for meeting emissions regulations, such as the FORS accreditation.

AdBlue can be bought in bulk. Even with a modest fleet, you’ll find that buying in bulk will save you money in the long run.

AdBlue helps protect agricultural crops from airborne pollutants by reducing noxious emissions, thus improving their quality. It also helps ensure that expensive farming equipment runs, and continues to run, properly.

SCR technology and AdBlue help optimise the combustion engine, meaning there is a reduction in fuel needed to perform the same mileage, helping you protect your bottom line.

How long does AdBlue last?

AdBlue has a consumption rate of one part AdBlue for every 20 parts of diesel fuel, or between 4-6% of diesel consumption, on standard Euro IV, Euro V and Euro VI trucks. This will of course vary based on the kind of vehicle being used (truck, coach, tractor…) as well as driving style and the kind of use – long journeys will be more economical than short journeys, so you can expect tractors to get through more AdBlue than coaches, due to the nature of their work.

On average, however, you can expect to use approximately 5 litres of AdBlue for every 100 litres of diesel.

AdBlue tanks vary in size from 32 litres to 112 litres, so you can expect to have to refill your AdBlue tank every 640-2,240 litres of diesel.
