What is a good AdBlue percentage?
In general, you can expect consumption to be between 5% to 15% of the diesel consumption. In other words, you will use about 10 litres of AdBlue for every 100 litres of diesel. Therefore you will be filling your AdBlue tank less frequently than your tank for diesel.
