On the road

Ad Blue

AdBlue is required by almost all heavy duty diesel vehicles (trucks, buses and coaches) marketed after October 1st 2006, when Euro IV entered into force.

To meet both Euro IV (October 2006) and Euro V (October 2009) emissions limits, almost all truck manufacturers have chosen the SCR technology using AdBlue.
  Engines using SCR technology must necessarily be run with AdBlue: if the AdBlue tank is empty, an on-board diagnostic system (OBD) will limit the engine performances.
This electronic protection ensures that vehicles’ NOx emissions remain below the legal limits.

What is ADBLUE?

AdBlue is a 32.5% solution of urea in deionised water, required by almost all trucks, buses and coaches operating in Europe.
Some light vehicles have also been marketed in the past two years, requiring also AdBlue (Mercedes, Audi, Mazda, VW, etc..).
AdBlue is a key product for all vehicles using SCR technology (Selective Catalytic Reduction), a technology that reduces toxic emissions, and particularly NoX.
AdBlue is neither a fuel used for combustion nor an additive, it is not even mixed with diesel, but injected in the exhaust system to produce a chemical reaction. It’s a non-toxic liquid, clear as water, that is safe to handle and does not harm the environment.    
AdBlue is manufactured according to strict industrial processes in order to meet both DIN 70070 and ISO 22241 standards

What is SCR?

SCR, or Selective Catalytic Reduction, is a technology that substantially reduces NOx (nitrogen oxides) emissions from the exhaust gasses, and is used to comply with both Euro IV and Euro V standards.
SCR system uses AdBlue and a metal catalyst mounted in the vehicle’s exhaust to reduce NOx to water vapour and atmospheric nitrogen. This reaction takes place after the combustion, in the exhaust system. It usually achieves a reduction of NOx emissions above 80% and allows the driver to get full performances form the engine. Having the engine set up for maximum efficiency allows for an estimated fuel saving of 3-5%.

What are Euro IV and Euro V?

Euro 4/5 emission legislation (g/kWh) Euro 4 Euro 5
Nitrogen oxide 3.50 2.00
Carbon monoxide 1.50 1.50
Hydrocarbons 0.46 0.46
Particles 0.02 0.02

The European Commission has defined the limits for vehicle contamination through Euro IV and Euro V standards. The legislation is binding and applies to all vehicles over 3.5t registered in the European Union after the implementation date.

Euro IV: in force since October 2006

Euro V: in force since October 2009

Euro VI: expected in 2014

Quality is guaranteed

Purity of AdBlue is essential and can only be guaranteed through a fully controlled supply chain, from production to storage. In fact, SCR catalysts are extremely sensitive to contaminants and can suffer irreversible and costly damages if impure AdBlue is used. If damages have resulted from mishandling of AdBlue, the vehicle’s warranty might be invalidated by manufacturers. Purchasing AdBlue in both canister and pump formats at Agip petrol stations, you will definitely make the right choice.  

Where can I buy AdBlue?

Multicard owners can find AdBlue® in 10 liter canister at a large selection of service stations across Europe, and increasingly in key locations at the pump.
