WHAT IS THE OPEL BLUEINJECTION TECHNOLOGY?

BlueInjection is the cutting-edge SCR diesel technology from Opel that uses AdBlue®* to further reduce the level of nitrogen oxides and work towards cleaner emissions.

 

*AdBlue® is a registered trademark from Verband der Automobilindustrie e.V.

WHAT BENEFITS THE ENVIRONMENT, BENEFITS YOU.

By owning a vehicle with BlueInjection technology you are helping to reduce harmful nitrogen oxides (NOx) emissions thus reducing your environmental footprint.

  • WHEN TO REFILL?

    Cars fitted with the BlueInjection system need regular AdBlue® top-ups also in between recommended service intervals. But don´t worry, an indicator in the dashboard will inform you when levels are running low.

  • HOW TO REFILL ADBLUE®?

    Top-up yourself thanks to the wide range choice of bottles available. Or just go to your local Opel dealer for the refill.

THE MOST FREQUENTLY ASKED QUESTIONS ABOUT BLUEINJECTION AND ADBLUE®.

What is AdBlue®?

AdBlue® (also called Diesel Exhaust Fluid) is an odorless, colorless clean and non-toxic fluid that consists purely of 32.5% urea and 67.5% water.
As it is mostly water, it freezes at -11°C (a 32.5% concentration is the lowest freezing point of a urea water solution), so to allow the vehicle to run under all conditions, all AdBlue® tanks are equipped with a heater that will defrost sufficient liquid for the emission reduction.

What is the SCR technology?

SCR means Selective Catalytic Reduction and is a technology used for reducing nitrogen oxides (NOx) from the exhaust gas of diesel engines. It is based on AdBlue® (also called Diesel Exhaust Fluid), a 32.5% urea solution in purified water, which is injected into the exhaust pipe. The urea in the AdBlue® releases ammonia (NH3) with the exhaust gas high temperatures and this ammonia reacts with nitrogen oxides (NO and NO2) in the catalytic converter to form harmless nitrogen (N2) and water (H2O) vapor.

Are there alternatives to SCR technologies?

SCR technologies are the latest state of technology on the path towards future emission requirements. It is the reason why Opel decided to implement BlueInjection (Opel's SCR technology) to the entire diesel fleet starting as of 2018.

What happens if I don´t top-up?

If the AdBlue® tank is empty, the car will not restart once the ignition is turned off! This is not a fault, but a legally required feature of the system. If this stage is reached the system will need a full top-up before the car can be restarted.

What should I pay attention to when buying AdBlue®?
  • First you should pay attention to the trademark AdBlue® and the standard ISO 22241-1 as well as DIN 70070.
  • Also we strongly advise you to only use bottles or canisters with a sealed interface to the filler pipe (usually with a screwed adapter). Like this you minimize risk of spillage.
  • Finally since AdBlue® has a limited durability, check the date of expiry before refilling.
Since AdBlue® is already used in commercial vehicles, can AdBlue® be refilled at truck filling stations?

We do not recommend to refill at the AdBlue® pumps that exist in many petrol stations for commercial vehicles (trucks and busses) as the flow rate is too high for a passenger car. In addition, most truck nozzles need to be released by a magnet insert in the filler head of the vehicle, which is not present in any Opel passenger car.

 

The good news is that there is a growing number of petrol stations across Europe, who offer low flow AdBlue® pumps for passenger cars. Refilling with such a pump is as easy as refilling diesel fuel.

What should I do if I spill AdBlue® onto my car and/or clothes?

If small quantities of AdBlue® come into contact with the vehicle’s paintwork, for example, wipe them off and if necessary rinse the area with water.
If you ever spill some AdBlue® on your clothes and/or hands, just rinse out thoroughly with clear water.

Is there an option to have a bigger AdBlue® tank?

Opel vehicles do not have this option. For each vehicle there is only one tank size that has been designed to optimize package and weight restrictions.

Who is the manufacturer of AdBlue®?

AdBlue® is a registered trademark of the VDA, for which General Motors (Opel's mother company) has a worldwide license covering all brands. It is manufactured by chemical companies, and only licensed manufacturers and distributors may use the name "AdBlue®".

  • The refill port is located next to the diesel fuel filler (or behind an opening in the rear bumper in the case of the Antara).
  • The filler cap is colored and can be opened by hand.
  • Re-fill can be done with all passenger car compatible bottles and nozzles available at many petrol stations or outlets. Or you use one of the AdBlue® refill pumps available at some gas stations that are specifically designed for passenger vehicles. Do not use truck / commercial vehicle AdBlue® pumps.
  • Top-up yourself thanks to the wide range choice of bottles available. Or just go to your local Opel dealer for the refill.
  • If small quantities of AdBlue® come into contact with the vehicle’s paintwork, wipe them off and if necessary rinse the area with water.

Each AdBlue® tank is equipped with sensors that will trigger a series of messages when the fluid is running low.

 

There will be three intervals:

  • When remaining range = 2,400 km (or lower depending on consumption) - a warning light will shortly be displayed on your on-board computer.
  • When remaining range < 1,750 km - a warning will come up and will be repeated every time you turn on the ignition.
  • When remaining range = 900 km – a warning will flash until you top up.

 

Attention! If the AdBlue® tank is depleted, the system will need a full top-up before the car can be restarted.

  • The innovative SCR (Selective Catalytic Reduction) technology: BlueInjection is a part of Opel's exhaust gas after treatment system.
  • The BlueInjection technology directly injects AdBlue® into the exhaust pipe triggering a chemical reaction that reduces harmful nitrogen oxides emissions, by converting them into nitrogen and water vapor, which are harmless to the environment.
  • AdBlue® is a clean, non-toxic, non-flammable, and odorless fluid that consists purely of 32.5% urea and 67.5% water.
