Frequently Asked Questions (FAQ) about AdBlue-Cars

Do I need AdBlue in my car?
If you use a modern, diesel powered car with a SCR-catalyst, you will need AdBlue. Check you cars manual for more information.

Why do I need AdBlue in my car?
Your vehicle needs AdBlue to reduce NOₓ emission. Due to the stricter emission legislation, diesel engines need to have cleaner exhaust gases. NOₓ is one of the emissions that causes acid rain. To meet the Euro 6 standards for diesel engine emission the use of Selective Catalyst Reduction-technology (and thus AdBlue) is required. The Euro 6 standards are into force from September 2014 for new passenger cars.

Is AdBlue hazardous?
No, Adblue is not a hazardous substance. It has no known significant effects or critical hazards. The raw material, urea, even occurs naturally in our digestive system. However, we strongly advise you not to ingest AdBlue or inhale AdBlue vapours, due to the risk of an allergic reaction.

How much AdBlue do I need?
How much AdBlue you use depends on your type of car. A full tank of AdBlue will last several tanks of diesel.

Estimated usage for Passenger cars:

  • Mid class diesel (For example Opel Insignia or Peugeot 508): 1 – 1,5 litre AdBlue for 1,000 km
  • SUV/MPV class diesel (for example Opel Zafira or VW Touran): 1 – 2 litres AdBlue for 1,000 km

What happens if my car runs out of AdBlue? 

Your car will warn you when the range for the AdBlue tank is 2400 km. What happens after the 2400 km warning is different for each brand, so please check your owner’s manual to find out what applies to your vehicle.

For example, a Opel Zafira Tourer will warn you at a range of 2400 km. Then, the car will limit your maximum speed to 100 km/h at a range of 900 km. The car will eventually limit the maximum speed to 50 km/h and it will warn you that the engine will not restart once the engine is turned off.
Make sure you carry an emergency supply on board or continue to the next distribution point without shutting down your engine.
