What Is AdBlue?

AdBlue is a highly purified colorless liquid. It contains demineralized water and urea (32.5%).

AdBlue is used with diesel engines and is also known outside of Europe as DEF, ARLA 32 or AUS 32.

The main active component of AdBlue is ammonia. This is chemically formed by hydrolising automotive urea, which is the main raw material for AdBlue. Urea is also used in the production of fertilizers and many more applications.

AdBlue is used with diesel engines using SCR technology. This technology (Selective Catalytic Reduction) reduces harmful emissions (NOx). AdBlue is injected into the catalyst of the SCR system,
where it triggers a chemical reaction with the ammonia. This chemical reaction converts the toxic nitrogen oxides (NOx) into nitrogen (N2) and water vapor (H2O). Water vapor and nitrogen are naturally occurring gasses that are harmless to the environment.

Do I need AdBlue In My Car?

AdBlue is mandatory in Diesel cars since the 1st of January 2017. If your car is less than 2 years old and is a Diesel car, then yes you might need to add some AdBlue into it!

To make sure this is the case, you simply have to check your user manual.

Why Do I need AdBlue In My Car?

Your vehicle needs AdBlue to reduce NOₓ emission. Due to the stricter emission legislation, diesel engines need to have cleaner exhaust gases. NOₓ is one of the emissions that causes acid rain. To meet the Euro 6 standards for diesel engine emission the use of Selective Catalyst Reduction-technology (and thus AdBlue) is required. The Euro 6 standards are into force from September 2014 for new passenger cars.

All commercial vehicle manufacturers have to meet the Euro 6 standards for diesel engine emission. Although Euro 5 emission standards could be met by different technologies, Euro 6 standards require the use of Selective Catalytic Reduction with AdBlue.

Here is a quick video that may help you understand a wee bit more.

What Happens If I Run Out Of AdBlue?

If you run out of AdBlue, your car will have limited performance. When you have switched off the car and your AdBlue tank is empty, it will not restart.
Your car, usually on the driver display screen will give you plenty of warnings that you are running low.
