Work toward a greener future and a cleaner environment
GAS is proud to partner with Chempro, supplier of AdBlue®, in the global effort to reduce harmful emissions from modern diesel engines.
Users of vehicles fitted with Selective Catalytic Reduction (SCR) converters will find AdBlue® at all GAS Petrol Service Stations.
- AdBlue® is not a fuel additive. This is why there is a separate AdBlue® tank
- If you put AdBlue® in your fuel tank by mistake, please do not start the engine, but ask a garage for help
- Put only AdBlue® in the AdBlue® tank; do not fill the AdBlue® tank with any other liquids!
- Prevent anything from contaminating AdBlue®
- If small quantities of AdBlue® come into contact with the vehicle's paintwork, wipe and rinse off with water
What is AdBlue?®
AdBlue® is colourless, synthetically produces, 32.5% solution of pure urea in demineralised water. It is also known as AUS 32 ((NH2)2CO), and is non-toxic.
Which vehicles require AdBlue®?
AdBlue® is used to treat the exhaust gass in diesel vehicles equipped with SCR technology.
What should you watch out for when buying AdBlue®?
Only use AdBlue® from official manufacturers that are licensed. Filling stations and sealed Adblue containers should always display the AdBlue® logo. The quality of AdBlue® is specified by ISO 22241-1.
Where can I obtain AdBlue®?
At all GAS Petrol Services Stations across New Zealand.
When do I have to fill up with AdBlue®?
The AdBlue® tank must not run dry. Your vehicle monitors the level of AdBlue® in the tank and will inform you several times, well in advance if AdBlue® has to be added. If the AdBlue® tank is empty, it will not be possioble to start the engine.
Where on my vehicle is the AdBlue® filler?
The filler pipe for the AdBlue® tank is located either directly next to the Diesel filler, or in the boot. This will vary by manufacturer, so be sure to follow the manufacturer's instructions when using AdBlue®.
Why is AdBlue® necessary?
Reducing pollutant emissions is an important challenge in vehicle design. Future exhaust standards will require, alongside reductions in CO2, reductions in nitrogen oxides (NOx) in particular. A new generation of catalytic converter has therefore been developed for diesel engines, using Selective Catalytic Reduction (SCR). Inside SCR converters, NOx are converted into harmless steam and nitrogen with the aid of the injected urea solution, AdBlue®. This reduces the amount of NOx emitted by up to 90%. SCR technology thus enables a vehicle to meet the Euro 6 standard.
