What is AdBlue?

AdBlue is a colourless and non-toxic solution of water and urea. However, it is important to note that the urea that is used in the making of AdBlue is of the highest grade and exceptionally pure, even more than the urea used in fertilisers and cosmetic products. Furthermore, the water used for AdBlue is also distilled and demineralised in order to make a pure solution.

How Does AdBlue Work in the Diesel Car?

The purpose of AdBlue in a diesel engine car is to reduce the emission of nitrogen oxide gas into the atmosphere. It uses a technology known as SCR or selective catalytic reduction to break down and neutralise toxic nitrogen oxides in the exhaust system.

This SCR technology has been in use for a long time. However, it was incorporated into diesel engine cars in 2016 due to environmental concerns.

Why It is Used in Diesel Engine Cars

We all know that car manufacturers have to follow strict rules to keep environmental concerns to a minimum. The latest set of rules, known as Euro 6, is particularly important and created some of the biggest challenges for car manufacturers because they have to minimise nitrogen oxide emissions.

That is why tiny amounts of AdBlue are injected into the exhaust system, which can neutralise the toxic emissions through SCR.

What Are the Benefits of AdBlue?

Emissions Reduction: AdBlue helps reduce harmful nitrogen oxide emissions in SCR-equipped diesel vehicles, promoting cleaner air and environmental sustainability.

Compliance with Emission Standards: AdBlue enables diesel vehicles to meet stringent emission regulations by effectively reducing nitrogen oxide emissions, ensuring legal compliance.

Improved Fuel Efficiency: AdBlue, when used with SCR systems, enhances fuel efficiency in diesel engines by optimising the combustion process and reducing the need for exhaust gas recirculation (EGR).

Engine Longevity: AdBlue protects engine components by preventing deposits, corrosion, and damage to catalysts, leading to longer engine life.

Cost Savings: Despite being an additional expense, the improved fuel efficiency achieved with AdBlue can result in long-term cost savings for diesel vehicle owners.

Availability and Accessibility: AdBlue is widely available at fuel stations and automotive stores, making it easily accessible for refilling the AdBlue tank in vehicles.

How to Remove AdBlue System?

AdBlue Removal Kits

Some companies are manufacturing and supplying AdBlue removal kits for those who understand the systems and want to remove the AdBlue system by themselves. These kits come with complete manufacturer instructions on how to use them and remove the system without any problem.

AdBlue Removal Service

If you are not comfortable with removing the AdBlue system by yourself, there are service providers who will send their technicians to your location and do the job for you. Hiring them provides a sense of relaxation, knowing that professional and experienced people are working on your car.

AdBlue Delete Software

AdBlue Delete software is a way to remove AdBlue from your onboard computer. It is done by sending an update to the onboard ECU. This method is particularly more technical than manual removal and hence should be done only by an experienced person.

AdBlue Emulator

The AdBlue emulator is a device that fools the onboard system by mimicking the AdBlue system. This device is particularly beneficial if you don’t want to face any systematic trouble regarding your missing AdBlue system.

How to Refill AdBlue in Your Car?

Refilling your AdBlue tank is very simple and can be done in two easy steps, i.e.:

Find Your AdBlue Tank

First, you will need to find out the AdBlue tank filler on your vehicle. It is normally located right next to the diesel filler on the vehicle. In some cases, it may be located in the bonnet or the boot. However, wherever it is located, it will be clearly marked with the name so that you can distinguish it easily.

Refill it with AdBlue

After that, simply take a funnel and pour the AdBlue liquid into the tank. The quantity of AdBlue depends upon the size of the tank; hence it can vary from vehicle to vehicle. It will be a good idea to take instructions from your vehicle’s handbook on how much AdBlue you should pour into your tank.

How Often Should AdBlue Tank Be Refilled?

The answer to this particular question is not definitive; rather, it depends upon different factors, such as:

  • The style of your driving
  • Driving conditions
  • Average daily driving distance

However, your onboard system should alert you when your vehicle is running low on AdBlue, and it’s time to give it a top-up.
