AdBlue for Diesel Engines Delivered Across the UK
AdBlue (AUS 32, ISO 22241 NOx reduction agent) is a diesel fuel additive that has been introduced to help eliminate the harmful emissions released by heavy vehicles used daily on our roads.
The use of diesel exhaust fluid (DEF) in modern diesel vehicles has become a requirement in order to help achieve the UK Government’s net-zero carbon-reduction target by 2050. It’s actually a legal requirement if you drive a modern heavy goods vehicle to limit the number of harmful exhaust emissions being emitted and as so, the use of AdBlue to achieve this is becoming more common in modern diesel-fuelled cars.
As an official VDA-licenced AdBlue supplier, Crown Oil can supply it to you at a competitive price in any quantity from 10 litres up to 36,000 litres. To purchase AdBlue from a supplier you can trust, choose Crown Oil.

What is AdBlue?
AdBlue is the common name used for AUS 32 diesel exhaust fluid (DEF), the diesel fuel additive that has been introduced to help eliminate the harmful exhaust emissions released by heavy vehicles used daily on our roads.
Using AdBlue is an effective means to reduce Nox emissions from diesel engines as it simply requires the addition of the fluid to your vehicle’s AdBlue tank.
As of October 2006, the use of the DEF in modern diesel vehicles fitted with SCR technology, including both passenger cars and HGVs above 7.5 tonnes (industrial vehicles, buses and trucks) has become a legal requirement to help achieve the UK Government’s net-zero carbon-reduction target by 2050.
As an official AdBlue supplier, Crown Oil can supply it to you at a competitive price in any quantity from 10 litres up to 36,000 litres. To purchase AdBlue from a supplier you can trust, choose Crown Oil.

What does AdBlue do? Why do modern diesel-engined vehicles require AdBlue?
Mixing AdBlue to diesel-engine exhaust fumes significantly reduces the release of mono-nitrogen oxide from engines.
Reducing Nox emissions is essential as it brings diesel-engined vehicles in line with Euro 6 emissions regulations, which called for a 67% drop in nitrogen oxides (NOx) released in the exhaust emissions of diesel cars.
There are two ways of achieving this reduction: through a Selective Catalytic Reduction (SCR) system and through exhaust gas recirculation. If your vehicle uses the SCR system, then you’ll need AdBlue.
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 emission in line with legal standards. Its performance will be returned when its AdBlue tank has been replenished.
The main benefit of bringing your fleet in line with Euro 6 standards is that it decreases the overall negative environmental impact of your business operations. It furthermore helps your company to gain more ‘green’ awards and accreditation for meeting emissions regulations.
AdBlue is completely non-flammable, safe to handle and easy to store.
How does AdBlue work?
Through a process called Selective Catalytic Reduction (SCR), AdBlue reduces the harmful emissions which are released by diesel engines as the fuel is burned. AUS 32 (Aqueous Urea Solution 32.5%) is the official name for AdBlue although the majority of people who use this additive call it AdBlue. It consists of 32.5% high purity urea and 67.5% deionized water, giving it its scientific name AUS32.
As diesel burns within your vehicle’s engine, it is forced through the exhaust system and expelled out into the air that we breathe. Before the emissions are released, the AdBlue formula is sprayed onto the harmful gases and the SCR Catalyst breaks down the bad stuff (Nitrous Oxides).
Once that’s done, all that’s left is nitrogen, water and CO2 to be expelled from the exhaust system. Check out the diagram below which shows AdBlue’s Nitrous Oxide reduction in action.
The AdBlue trademark is currently held by the German Association of the Automobile Industry (VDA (Verband der Automobilindustrie)). Clicking the link will take you to their page with additional notes about this diesel additive.
Modern heavy goods vehicles fitted with SCR technology are required to use AdBlue by law. As of October 2006, all vehicles above 7.5 tonnes are manufactured with this technology. This includes industrial vehicles, buses and trucks. Your diesel fuel will never come into contact with the solution as it is stored in its own designated tank with a sensor system and gauge. It is sprayed onto the exhaust fumes soon after combustion and works from there.
Is AdBlue a fuel additive?
AdBlue fluid is an additive used after the combustion process and isn’t always considered an additive in the conventional sense. A fuel additive is generally defined as a liquid that is added to the fuel itself, whereas AdBlue is added to the exhaust fumes before they’re released into the atmosphere.
How long does AdBlue last?
The rate of consumption for AdBlue is a ratio of approximately 1:20 of the rate of diesel fuel usage on standard Euro IV, Euro V and Euro VI trucks, so its relatively low AdBlue solution is sprayed into the exhaust stream of modern diesel engines as a post-combustion process.
For passenger cars, 1.5-litres of AdBlue will be used every 620 miles.
Our guide to AdBlue has a more detailed estimate of AdBlue fluid consumption.
What emission reductions are there from using AdBlue?
Water vapour, nitrogen and carbon dioxide are released from the vehicle’s exhaust when DEF is used. NOx (nitrous oxides) are usually released from a vehicle’s exhaust which is damaging to the environment. Through the process of SCR, the AdBlue solution breaks down the NOx emissions and outputs much cleaner and safer levels of emissions.
To reduce the pollutant levels across Europe, using SCR technology has become a legal requirement when manufacturing heavy goods vehicles (HGVs).
How do I store AdBlue?
While storing AdBlue is straightforward, it must be kept between -11oC and 30oC to maximise its 12-month lifespan. As well as supplying a wide range of storage tanks for fuels, we can also provide AdBlue storage tanks to safely store the diesel additive, in addition to both hand and electric pump options depending on your requirements.
Since AdBlue is corrosive, these pumps make the dispensing process easier and safer, but you should always ensure you’re using it with care and be sure to wash your hands thoroughly after contact.
What is AdBlue made of?
AdBlue is technically known as AUS 32, derived from Aqueous Urea Solution 32.5%. AdBlue contains 32.5% high purity urea and 67.5% of deionised water.
Is all AdBlue the same?
AdBlue is, in fact, a trademark of VDA (Verband der Automobilindustrie), but so long as the diesel exhaust fluid you buy is certified to meet the AUS 32 criteria, and meets ISO 22241, then there is no difference between which brand you use.
What happens if you run out of AdBlue?
Typically, before running out, a warning light will go off on your dashboard to indicate you are low on diesel engine fluid. However, once this runs out, vehicles will not start if the AdBlue tank is empty, as the emissions that would be released from the engine would be too high.
I’ve put AdBlue in my diesel tank — now what?
AdBlue is not an additive to diesel fuel — it’s a NOx reduction agent that is sprayed into the exhaust fumes, so it’s unwise to start your engine if you’ve poured AdBlue into your diesel tank, as you’ll be letting water into your engine. Call roadside assistance or the appropriate emergency service if this happens to avoid engine breakages.
Is AdBlue pig’s urine?
No. The reason for this misconception is because AUS 32 diesel engine fluid is made from a solution of urea and deionised water, and urea is most commonly known as the chemical found in urine. Due to the industrial amounts of urea that needs to be produced, the urea used in AdBlue is synthetically made.
