Will I have to use AdBlue®? Why?
All heavy vehicles with diesel engines registered from the 1st October 2006 onwards have to comply with the norm Euro 4 regarding exhaust emissions. So to comply with the environmental standards Euro 4 and Euro 5 (more recent) on trucks’ exhaust emissions, the vast majority of the manufacturers chose the SCR technology which requires the use of an aqueous urea solution 32,5%.
Although there is an alternative technology, EGR leads to an increase in diesel consumption, so itis noticeable that most manufacturers chose for SCR and from the 1st of January 2015 onwards (when the Euro 6 standard will come into force) all will have to use it. In the United States the EPA 2010 standard also leads to the use of the SCR technology.

What is the SCR Technology (selective catalytic reduction)?
The SCR technologyreduces the diesel engines emissions because when the nitrogen oxides (NOx) go through the exhaust system, they blend with AdBlue® and transform themselves in nitrogen and steam (which are natural air components) given a catalytic reaction boosted by heat.

What is the expiration date for AdBlue®?
It is operational for approximately 1 year, as long as it is stored at a temperature between -11ºC and 30ºC, and provided that its long-term exposure to different weather conditions – particularly the sun – is avoided.
AdBlue® may freeze if the temperature is below -11°C; nevertheless, it does not suffer any damage during the freezing process and once it gets back to the original status, the solution will regain its concentration and quality. The quantity of urea included may reduce if AdBlue® is kept at temperatures above 30°C and, in this case, there is also the possibility to form ammoniac.

Is AdBlue® an additive for diesel?
No. It has a separate system that never gets in touch with diesel.

What are AdBlue® consumption levels?
On average, the consumption of AdBlue® is around 1,5 litres per 100 km (driving on motorways).

What is the Law Euro 4, Euro 5 and Euro 6?
Legislation that makes it compulsory for diesel vehicles to reduce the engine emissions.
Euro 4 standard came into force on the 1st October 2006.
Euro 5 standard came into force on the 1st October 2009.
Euro 6 standard will come into force on the 1stJanuary 2015.
