All commercial diesel-engine vehicles that weigh above 7.5 tonnes and vehicles manufactured after October 2006 (Euro IV and Euro V) are fitted with Selective Catalytic Reduction (SCR) technology. For SCR to function – and for the vehicle to function – AdBlue must be injected into the exhaust gases as a post-combustion process. How do I know if my car uses AdBlue? The cost of AdBlue fluctuates due to the cost of the raw products that make up the solution; urea and water. There are no active urea processing plants in the UK which increases demand and therefore price. Buying in bulk means you can avoid any sudden price increases as a result of raw materials. Benefits of AdBlue AdBlue® is made of a colourless mixture of high-purity urea (32.5%) and deionised water (67.5%), as set out in the ISO 22242 standard. Urea contains ammonia; the active ingredient in AdBlue® that reacts with NOx and neutralises it before it enters the atmosphere. AdBlue has become key in helping reduce NOx output from engines as standards have sharpened for transportation vehicles, as well as off-road vehicles and passenger engines. What’s more, when your SCR-equipped vehicle’s AdBlue levels are running low, a warning alert will appear on the dashboard. If it runs out completely, the car will lose power and reduce its emissions in line with legal standards. Its performance will be returned when its AdBlue tank has been replenished.

As well as reducing NOx without harming engines, TotalEnergies AdBlue® also features TotalEnergies ClearNOx, an additive within the solution that cleans SCR systems, improving their cold and stop-start performance. Reducing clogging in exhaust, ClearNOx has been shown to remove the risk of clogging for up to 50,000km and reduce maintenance costs. 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.Unlike diesel or petrol it is not injected into the engine,instead it is released into part of the vehicle’s exhaust. When heated in the exhaust, it decomposes into ammonia and CO₂. The NOx from the engine exhaust reacts inside the catalyst with the ammonia and the harmful NOx molecules in the exhaust are converted to harmless nitrogen. In fact, AdBlue® can reduce your NOx emissions by up to 90%! AdBlue® can freeze at temperatures below -11°C, however it will usually thaw due to the heat of the engine in cold winter conditions, without any change in concentration or effectiveness. While there are different names for AdBlue®, such as Bluedef, BlueTec and so forth, all mixes should contain the same solution of 32.5% urea and 67.5% de-ionised water. The German Association of the Automotive Industry’s AdBlue® marque can be confidently relied upon to meet these requirements, while others may not.

The cost will depend on your fleet and its consumption will depend on your vehicles and their usage. If you own a diesel, chances are you need to use AdBlue® – a diesel exhaust fluid (DEF) used in millions of cars, light commercial vehicles, HGVs, buses and coaches across the world. But what is it, what does it do, what is it made of, how does it work and how do you best use it to ensure your car performs efficiently and safely? Read on to learn more and have all your AdBlue® questions explained. AdBlue is a colourless liquid made up of high purity urea and deionised water, and vehicles with SCR technology will have a separate tank filled with it.

What does AdBlue do?

Since 2006 the 4 th edition (Euro 4) of the EU law regarding diesel emissions came into effect. The laws become stricter with every update and the 4 th edition made it compulsory for all new lorries to have SCR fitted on them. AdBlue isn’t hazardous to the environment – so you can dilute a small spill with water and simply mop it up.

The transport industry is the biggest contributor of greenhouse gas emissions – and diesel-powered vehicles and equipment account for almost half of all nitrogen oxides (NOx). As so, the UK government is putting increasing pressure on diesel car manufacturers to do something about the substantial amount of harmful emissions released by diesel exhausts. AdBlue is widely available throughout the UK, however, varies in price significantly. Nationwide Fuels is a nationwide competitive supplier of high-quality AdBlue, which you can buy in quantities from 10-litres up to 36,000 litres and more. Make sure your fleet of vehicles is safe, legal and helping the environment. If you’ve got a modern diesel car, AdBlue® can help to keep it running smoothly. The mixture of urea and deionised water is used in vehicles with a selective catalytic reduction converter, where it’s injected into the exhaust system in precise doses. It will slash harmful NOx emissions by up to 80%, which is great for the environment and keeps your vehicle up to scratch in meeting Euro 6 emissions standards.This releases ammonia which is a catalyst to a chemical reaction and converts dangerous chemicals into nitrogen, water vapour and CO 2 – all which are unharmful to our lungs and the atmosphere. 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. It also increases your fleet’s MPG and helps your business achieve greener goals and accreditation. It’s impossible to drive without AdBlue® – your engine will not start, and you’ll see a notification noting ‘AdBlue® is empty’. A notification will also appear when your AdBlue® tank is running low. 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 is a non-toxic, non-flammable and odourless solution that contains 32.5% of high purity water and 67.5% of deionised water. Why is AdBlue needed? For information on your vehicle’s AdBlue requirements, head to the handbook. What happens if I run out of AdBlue/don’t use AdBlue? If your AdBlue freezes when temperatures drop below -10°C, don’t worry – once it’s thawed out, it’s safe to use Polluting chemicals and compounds, including Nitrogen Oxide and Nitrogen Dioxide, are produced when diesel engines burn fuel. These elements build up in the air and produce smog and acid rain. If you’re wondering how long AdBlue® lasts and how much you should use in your vehicle, the rate at which your AdBlue® depletes is around 1 litre for every 350 to 600 miles. The exact rate at which you should top up your AdBlue® depends on your vehicle’s engine size, your driving style, and the size of the vehicle’s AdBlue® tank, which varies between 5 and 20 litres in size.

SCR is a reliable way of cleaning your engine. The exhaust after treatment technique works by converting nitrogen oxides (NOx) into diatomic nitrogen (N2) and water using ammonia or urea solutions. SCR equipped engines use a Diesel Exhaust Fluid (DEF) such as AdBlue and this is stored in a separate tank in the system and is injected into the exhaust stream. The injection causes a chemical reaction which occurs in the SCR catalytic converter.
