How much AdBlue does a truck use per 100 km?
A Euro 6 HGV uses 1.3 to 1.7 litres of AdBlue per 100 km - roughly 4 to 6 percent of diesel. Calculate your fleet AdBlue costs and refill intervals.

A Euro 6 heavy truck uses 1.3 to 1.7 litres of AdBlue per 100 km - roughly 4 to 6 percent of diesel consumption. At typical European pump prices of EUR 0.65 to 1.20 per litre, that adds EUR 1.00 to 1.80 to running costs per 100 km.
How do you calculate AdBlue consumption for an HGV?
The ISO 22241 standard establishes that SCR systems on Euro 6 engines consume AdBlue at 4 to 6 percent of diesel volume. Yara International , one of Europe's largest AdBlue producers, publishes the same guidance for Euro 5 and Euro 6 HGVs. To estimate your own figure, multiply your diesel consumption by 0.05 as a mid-range factor.
| Diesel use (L/100 km) | AdBlue (L/100 km) | Daily AdBlue cost (500 km, EUR 0.90/L) |
|---|---|---|
| 25 | 1.25 | EUR 5.63 |
| 30 | 1.50 | EUR 6.75 |
| 35 | 1.75 | EUR 7.88 |
European pump prices for AdBlue ranged from EUR 0.65 to EUR 1.20 per litre in 2026, according to TrucksOnTheMap's haulier cost analysis . You can check live AdBlue and diesel prices by country on Logifie's free fuel map , updated daily across EU member states.
How much does AdBlue add to your running cost?
At EUR 0.90 per litre and 1.5 litres per 100 km, AdBlue adds EUR 1.35 per 100 km - roughly EUR 1,350 per vehicle per year at 100,000 km. Vehicles dosing inefficiently signal early injector wear or a faulty NOx sensor.
Most Euro 6 artics carry a 50 to 75-litre AdBlue tank. At 1.5 litres per 100 km, a 75-litre tank lasts roughly 5,000 km - around seven to ten days for long-haul work.
Running out triggers a progressive derate: torque limitation, then a 20 km/h speed cap, then an engine restart lock. For tank-level alerts before a forced stop, GPS tracking can surface AdBlue warnings in real time.
Euro 7 type approvals for new trucks begin from 2027 and may bring improved SCR efficiency, but Euro 6 figures are the operative baseline for the installed fleet for several more years. For a full comparison, see the guide to Euro 6 and Euro 7 truck standards .
Frequently asked questions
What percentage of diesel is AdBlue for trucks?
For a Euro 6 HGV, AdBlue consumption is 4 to 6 percent of diesel volume per ISO 22241. At a 5 percent ratio and 30 litres of diesel per 100 km, that is 1.5 litres of AdBlue. Euro 5 trucks with less efficient SCR calibration often sit at the lower end of this range.
How far can a truck travel on a full AdBlue tank?
A Euro 6 artic with a 75-litre tank covers roughly 4,300 to 5,700 km on a full tank. Smaller 50-litre tanks give around 2,900 to 3,800 km. Most drivers top up AdBlue every two to three diesel fills.
Does AdBlue consumption change with load or speed?
Yes. Heavier loads and higher speeds increase diesel consumption, and AdBlue dosing is proportional to diesel burn. Fully laden motorway running above 85 km/h pushes consumption toward 6 percent. Lightly loaded regional driving can drop it toward 4 percent.
What happens if a truck runs out of AdBlue on the road?
Euro 6 regulations require a progressive engine derate: a warning, then torque limitation, then a 20 km/h speed cap, then a restart lock on the next engine-off. The truck cannot continue until the tank is refilled - there is no override.
