AdBlue is a urea-based fluid that is used in diesel engines to reduce emissions of nitrogen oxides (NOx) in the exhaust gas. It is injected into the exhaust stream and does not directly affect the fuel consumption of the engine. However, in some cases, using AdBlue may have a slight impact on fuel consumption indirectly.
For example, if the AdBlue system is not functioning properly, such as a malfunctioning injector, it can cause the engine to run in a reduced power mode and increase fuel consumption. Additionally, if a vehicle is driven with a low AdBlue level, it may also cause the engine to run in a reduced power mode and increase fuel consumption.
It’s important to ensure that the AdBlue system is functioning properly, and to refill the AdBlue tank as soon as possible, when low, to ensure the vehicle continues to operate normally and meet emissions regulations.
It’s also important to note that the use of AdBlue is mandated by emissions standards and its use may help to reduce emissions of nitrogen oxides (NOx) which is a benefit for the environment and the air quality in the long term, even though it may have a slight impact on fuel consumption.
