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 gassesthat are harmless to the environment
Emission legislation for transportation and off-road vehicles will become more demanding. Euro 6 (due in2014) will require the use of SCR technology and AdBlue for all transportation vehicles and passenger cars. So it is likely that you will require AdBlue in the future.
As a fleet owner you will also need AdBlue for your replacement vehicles. Since 2006, most newly built trucks and buses are fitted with an SCR system that uses AdBlue. Putting new trucks into use will automatically require you to familiarise yourself with AdBlue. Current developments also point towards an increase in the use of catalytic reduction in off-road vehicles. Stage I to IV (emissions legislation due in 2014) demand cleaner off-road vehicles with lower NOx output. AdBlue is the best way to achieve this.
2014 will also change the diesel technology in passenger cars. SCR and AdBlue will become a standard feature for diesel driven cars, which will make AdBlue a part of daily life.
All commercial vehicle manufacturers have to meet the Euro 5 and Euro 6 standards for diesel engine emission. Although Euro 5 emission standards could be met by different technologies, Euro 6 standards (into force January 2014) require the use of Selective Catalytic Reduction with AdBlue.
Stage I to IV legislation applies to most off-road machinery as used in construction, for farming and other applications. Whether you need to use SCR technology and AdBlue accordingly, depends on the emission levels of your machine or vehicle.
More information on the appliance of legislation on your vehicle can be obtained from the manufacturer.
Local distribution: – Approximately 500L in one year.
- Mid class diesel
- (For example Opel Insignia or Peugeot 508):
- 1 llitre AdBlue for 1,000 km
- SUV/MPV class diesel
- (for example Opel Zafira or VW touran): -5 litre AdBlue for 1,000 km
.
AdBlue should always be a colorless clear liquid. If you buy drums or cans, watch out for brand names that are similar to AdBlue. You could be dealing with a brand of inferior quality. Make sure that you buy AdBlue from a VDA licensed partner and look for this text on the container or dispensing system: “AdBlue according ISO 22241”. You can also look for the GreenChem logo

No, the engine will not be damaged when you run out of AdBlue. You can continue to the next AdBlue distribution point or use your emergency supply at the next stop. However the engine performance could be effected until you fill up.
No, the engine will not shut down, but some engines automatically limit engine performance when AdBlue supplies are depleted. If your engine is equipped with SCR technology, your vehicle will lose power, and reduce its emission according to legal standards. The vehicle’s performance will be restored when AdBlue levels are up again.
Do not start your engine! Depending on the amount of AdBlue, you may damage your engine when you start it. You should empty and clean your tank. You will have to empty the whole tank and discard the mixture.
For further instructions on emptying and cleaning your tank, please contact your vehicle supplier.
You can recognise your AdBlue tank by its blue cap or an AdBlue label, but it is a totaly separate tank.
The filling point is often fitted near your diesel cap. Some passenger cars have an AdBlue tank in the boot or in the engine bay.
The opening for your AdBlue tank is narrower than the opening for a diesel tank, so you should not be able to put diesel in the wrong tank (the nozzle does not fit).
AdBlue is not dangerous to the environment. A small AdBlue spill can be diluted with water. It is best to mop up the spillage and avoid flushing it down a drain or waterway. In case of a large spill, try to prevent the spillage from entering drains or waterways. Contain the spill with sand, earth or your spill kit and dispose of it properly.
Spill kits are available in different sizes and sets.
Note: The surface on which you spill AdBlue may become slippery. Make sure that you clean up the spill as quickly as possible to prevent slipping and falling.
No, never try to reuse spilled AdBlue! Spilled AdBlue will always be contaminated. Using contaminated AdBlue can cause costly damage to your vehicles’ SCR system, so no matter how great the spill, you cannot reuse it .
If you’re driving a newer diesel car, chances are it comes with AdBlue technology. It won’t be obviously advertised, but manufacturers like Volkswagen, Audi, Range rover,Toyota,Renault, BMW,Opel,Man, Mercedes, Peugeot, Citroen, Jeep Cherokee and Jaguar all feature AdBlue technology.
