Consumption

AdBlue® consumption varies depending on factors such as engine load, terrain, engine size, and temperature. The most practical way to estimate AdBlue® usage is relative to diesel consumption, based on experience from operating SCR systems.

Commercial Vehicles

AdBlue® consumption for heavy goods vehicles (HGVs) and light commercial vehicles (LCVs) depends on vehicle type (truck, refuse vehicle, van), journey type, and engine workload. Typically, AdBlue® consumption ranges from 5% to 15% of diesel use—approximately 10 litres of AdBlue® for every 100 litres of diesel. This means the AdBlue® tank requires refilling less frequently than the diesel tank.

Estimated weekly AdBlue® consumption for HGVs (litres):

Quantity of Diesel per week (litres)
Application:	1000	2500	5000	7500	10000	15000	20000	25000	35000	50000
Light duty (<18 tonne GVW)	45	90	165	240	315	465	615	765	1065	1515
Medium duty	75	150	275	400	525	775	1025	1275	1775	2525
Heavy duty (>35 tonne GVW)	90	180	330	480	630	930	1230	1530	2130	3030
Quantity of AdBlue per week (litres)

Bus & Coach

AdBlue® use depends mainly on route type, as it only injects at exhaust temperatures above 200ºC. For planning purposes:

• Local/Urban routes: Approx. 9 litres per day per vehicle
• National/Long-distance routes: Approx. 15 litres per day per vehicle

Consult vehicle manufacturers for precise figures.

       

Agricultural & Construction

Usage varies widely due to differing engine demands and operations (e.g., tractors used stationary or in motion). Typically, AdBlue® consumption is 5% to 10% of diesel use.

Passenger Cars

Passenger cars generally have smaller engines and lighter operating loads than commercial vehicles, resulting in lower AdBlue® usage. However, cars have smaller AdBlue® tanks and may require top-ups between service intervals.

Only use genuine AdBlue® in your vehicle; do not dilute or substitute with other fluids.
