What is my AdBlue® range and when do I need to fill up?
The range for the same diesel model varies from one car to the next
The range of an AdBlue® tank for a passenger car depends on several parameters, such as the capacity of the tank and the type of driving being done. The manufacturer obviously suggests a standard range in order to provide individuals with a rough guideline; but your personal driving style will significantly affect this standard measurement. The range of AdBlue® for your car given by the manufacturer varies according to the tank capacity (from 8 l to 30 l), the type of driving (sporty or not) and the nature of driving (short or long trips).
How do various factors influence AdBlue® consumption?
When the engine is cold, no AdBlue® is consumed. The more the engine temperature rises, the more nitrogen oxides (NOx) are produced. How much AdBlue® is injected at the engine outlet is often based on mapping of NOx discharge depending on driving conditions, especially the engine speed and vehicle load. Therefore, the heavier your load and the more you drive with your foot to the floor, the more AdBlue® your car will consume.
Additionally, the type of driving greatly affects NOx production: stopping and starting as you drive through a city will use much more than driving on the motorway. The mileage given by your manufacturer is therefore just an average. Currently, it is necessary to fill up with AdBlue® once or twice per year. The evolution of the Euro VI European standard may mean that you will need to fill up more often, approximately every four or five times you fill up with diesel.
