AdBlue®

Reducing Emissions, Driving Sustainability

Are you a diesel vehicle owner? It is highly likely that you are required to use AdBlue®. This is utilised in a high number of cars, light commercial vehicles, HGV’s and public transport worldwide.

But what is it, its functionality, and usage? Continue reading to have all your AdBlue® questions answered. 

What is AdBlue®?

AdBlue® is a toxic free, colourless, odourless, non-flammable and biodegradable solution intended to help diesel vehicles reduce the harmful exhaust emissions. It helps to cut down harmful nitrogen oxide (NOx) emissions which are created during the combustion process and turn them into harmless nitrogen and water vapor.

AdBlue® ingredients are a mixture of high-purity urea (32.5%) and deionised water (67.5%), as set out in the ISO 22242 standard. AdBlue® can also be known as AUS 32 diesel exhaust fluid (DEF).

How does AdBlue® work?

AdBlue® works alongside vehicle engine selective catalytic reduction (SCR) systems and after the exhaust gas passes through the diesel particulate filter, AdBlue® is then sprayed and mixed into it via a dosing control system as it enters the SCR catalytic converter. This is where the ammonia within the urea reacts with NOx in the exhaust stream, neutralising it to form harmless nitrogen and water vapour, while additionally reducing total fuel consumption by 2-6%. AdBlue® and SCR systems are highly effective, reducing NOx emissions by up to 90%, hydrocarbon and carbon monoxide emissions by 50-90%, and particulate emissions by 30-50%. 

AdBlue Warning Light

What happens if I run out?

You should be notified on your dashboard before running out by an AdBlue® warning light showing it is time to top up. It is very important that you keep your vehicles and equipment topped up with AdBlue® otherwise it will not be able to meet the emissions standards. If it does not meet these standards then it can lead to severe consequences, including large fines and penalties imposed by regulatory authorities.

How long does AdBlue® last? How much should I use?

This depends on several different things, such as the journey, your driving style, mileage, and environmental conditions. On most vehicles it should indicate on your dashboard when you need a top-up of AdBlue®. 

In a standard passenger car, it will usually use around 1 litre for every 350 to 600 miles however this is just an estimated figure. To find out the exact usage rates then please refer to your vehicle’s handbook or a qualified mechanic.
