Find out more about the benefits of AdBlue in our beginner's guide to AdBlue. We describe the ways AdBlue can assist with complying to emissions regulations.
What Is AdBlue?
AdBlue, also known as diesel exhaust fluid (DEF), is a vital component in reducing the harmful emissions produced by diesel-powered vehicles. Essentially, AdBlue is a branded version of DEF, consisting of a solution of distilled water and urea, commonly found in urine and fertilisers. It is notable for its non-toxic nature, colourlessness, and faintly sweet odour. It may feel slightly sticky when touched, but it can be easily washed off.
The primary purpose of AdBlue is to play a pivotal role in mitigating the release of harmful pollutants, particularly nitrogen oxides (NOx), from diesel engines. It achieves this through a chemical reaction within the vehicle's selective catalytic reduction (SCR) system, wherein AdBlue facilitates the conversion of these hazardous emissions into less harmful compounds, such as nitrogen and water vapour.
In essence, AdBlue serves as an eco-conscious additive, contributing to cleaner air quality and enabling compliance with stringent emissions regulations. To ensure the efficient and environmentally responsible operation of modern diesel-powered automobiles, many of them are equipped with AdBlue tanks and dispensing systems. By doing so, these vehicles are better equipped to meet emissions standards and reduce their overall environmental impact, making AdBlue a crucial ally in the quest for cleaner transportation.
How Much Does AdBlue Cost?
AdBlue costs can vary depending on several factors, primarily driven by the brand you choose and the method of refilling you opt for. Typically, a 10-litre container of AdBlue is priced in the range of £10 to £15.
However, it's essential to consider that the cost may fluctuate slightly based on the brand's reputation and market positioning.
When it comes to refilling your vehicle's AdBlue tank, you have a choice between using a public pump or purchasing containers of AdBlue for self-refilling. If you decide to use a public pump, the cost is typically calculated per litre.
The precise price per litre can vary from one pump station to another, often influenced by location and regional pricing differences.

If you prefer the convenience of pre-packaged containers, you'll find that their cost is relatively consistent within the aforementioned price range. Keep in mind that using pre-packaged containers offers a degree of flexibility and accessibility, allowing you to refill your AdBlue tank at your convenience without relying on specific pump locations.
In summary, while the cost of AdBlue can fluctuate slightly depending on the brand and method of refilling, a 10-litre container generally falls within the £10 to £15 range. Whether you opt for public pumps or pre-packaged containers, the affordability of AdBlue makes it a viable choice for reducing harmful emissions in diesel vehicles.
What Are The Benefits Of AdBlue?
AdBlue stands as a crucial solution injected into a vehicle's exhaust gas flow via Selective Catalytic Reduction (SCR) technology, playing a pivotal role in the ongoing effort to combat harmful emissions. When introduced into the exhaust stream, this solution triggers a chemical reaction with Nitrogen Oxide (NOx) compounds, fundamentally altering them into benign nitrogen and oxygen molecules before they exit the vehicle. This process yields a substantial reduction in NOx particle emissions, which are notorious for their contribution to air pollution and associated health risks.
The advent of diesel exhaust fluids like AdBlue was a strategic response to address this issue, curbing the release of these detrimental emissions that would otherwise disperse into the atmosphere, further exacerbating environmental problems like the Greenhouse Effect and global warming. The environmental merits of AdBlue extend beyond its immediate role in emission reduction.
Notably, it garners recognition within the United Kingdom as a transportable fluid that falls into the safe minimum risk category. This classification underscores the safety and responsibility associated with the use of AdBlue, confirming that vehicles utilising this solution do not pose additional hazards to themselves or others sharing the road. By opting for AdBlue, the automotive industry takes a substantial step toward greater environmental responsibility, making a significant contribution to the preservation of our planet.
In essence, AdBlue serves a dual purpose: actively mitigating harmful emissions while simultaneously embodying a safe and responsible choice for vehicle operation. As the automotive sector increasingly embraces the adoption of AdBlue, it aligns itself with broader sustainability goals and contributes to the global endeavour to safeguard the environment.
The integration of this technology signifies a collective stride toward cleaner air, reduced greenhouse gas emissions, and a more sustainable future for generations to come. With AdBlue at the forefront of these efforts, we move closer to achieving a healthier, cleaner, and more sustainable world, wherein the well-being of both humanity and the planet are prioritised and protected.
How Should I Store AdBlue?
Properly storing AdBlue is of utmost importance to preserve its effectiveness and maintain its quality over time. Here are some essential steps to ensure the optimal storage of AdBlue:
First and foremost, it's crucial to select an appropriate storage location for the AdBlue container. This location should be cool and temperate, safeguarded against extreme temperatures. Excessive heat can degrade the solution, potentially compromising its performance.
Therefore, avoid exposing the container to direct sunlight or other heat sources. When the AdBlue container is not in use, make sure it is securely sealed. Proper sealing prevents contamination and evaporation, preserving the integrity of the AdBlue solution.
By sealing it well, you can be confident that the AdBlue will remain in its purest form until it's needed for use. It's important to note that AdBlue has a freezing point, typically around -11°C (12°F). To prevent freezing, store the solution in an environment where the temperature does not drop below this threshold.

If, by any chance, the AdBlue solution freezes, it should be allowed to naturally warm up to its optimal operating temperature before use. Attempting to thaw it artificially can potentially compromise its efficacy.
By following these storage recommendations, you can ensure that your AdBlue remains in excellent condition, ready for use whenever required. Proper storage is a key factor in preserving the quality and performance of AdBlue, thus contributing to the overall effectiveness of reducing harmful emissions from diesel engines.
Does My Vehicle Need AdBlue?
The adoption of AdBlue technology in diesel vehicles produced post-2015 has become increasingly prevalent, primarily in response to the stringent Euro 6 emission standards. This vital integration reflects automakers' commitment to not only meet but exceed the ever-tightening regulations governing exhaust emissions. To help vehicle users identify these eco-conscious models, some manufacturers have incorporated descriptors such as "Blue HDi" or "SCR" in the vehicle's name or description, subtly hinting at the presence of AdBlue systems.
Euro 6 standards place significant emphasis on the reduction of harmful exhaust emissions, with a particular focus on curbing nitrogen oxide (NOx) emissions. AdBlue systems are designed to effectively address this challenge. They function by injecting AdBlue, a solution consisting of urea and distilled water, into the exhaust stream. Within the catalytic converter, AdBlue undergoes chemical reactions that convert NOx emissions into less harmful nitrogen and oxygen.
This transformation aligns with the overarching objective of Euro 6 standards: to minimise the adverse impact of diesel vehicles on air quality and public health. While vehicle models labelled "Blue HDi" or "SCR" provide subtle hints about their AdBlue systems, it's essential for vehicle owners and operators to have definitive information regarding their vehicle's AdBlue compatibility. The most reliable source of this information is the vehicle's handbook or owner's manual.
By consulting these resources, users can gain comprehensive insights into their vehicle's environmental features and ensure proper AdBlue utilisation. Taking a proactive approach by referring to the handbook or manual not only guarantees compliance with emissions regulations but also empowers vehicle owners to actively contribute to reduced emissions and a cleaner, more sustainable driving experience.
By embracing AdBlue technology and adhering to Euro 6 standards, the automotive industry takes significant steps toward a greener and more environmentally responsible future, where cleaner air and reduced emissions benefit both society and the planet.
