Consumption of AdBlue® and Diesel consumption
Is the consumption of AdBlue® proportional to the consumption of Diesel?
AdBlue® is not a fuel consumed by the engine. Indeed, this comprehensive fluid is not mixed with diesel but remains stored in a dedicated tank of the vehicle. It happens at the output of the engine to rid the exhaust of polluting particles and NOx (oxides of nitrogen). Its consumption is directly linked to the diesel consumption but not completely proportional to it. In general, the ratio between the two varies from 4% to 10%.
What factors influence the consumption of diesel?
Your consumption of diesel per kilometre depends on the power of your engine and other factors related to your driving style. You will find several articles on the internet that share good practices to optimise your consumption and improve the autonomy of your diesel refuelling.
The golden rule is to drive your car as if you were taking your driving license test. You should drive as soon as the engine starts. Mastering the art of gear changes during acceleration is also an important factor in reducing consumption. Try to keep from revving the engine up too high.
Is it enough to optimise the diesel consumption to reduce that of AdBlue®?
Optimisation of diesel consumption certainly reduces the AdBlue® consumption but other good practices are aso necessary.
