The most convenient AdBlue network in New Zealand.

You can find AdBlue at more than 45 truck stops right now across the Z and Caltex truck stop network.

AdBlue diesel exhaust fluid is designed to work with Selective Catalytic Reduction (SCR) technology. It was developed by leading engine manufacturers to reduce vehicle exhaust nitrous oxide (NOx) emissions and help meet vehicle regulated emission targets.

Why use AdBlue?

AdBlue diesel exhaust fluid is designed to work with Selective Catalytic Reduction (SCR) technology.

AdBlue reduces your NOx emissions by up to 90%, compared with non-SCR vehicles*.

*Based on average usage by SCR technology vehicles and provided as a guide only. Individual use may vary based on various factors including vehicle type and age, the route and the driver.

How AdBlue works

AdBlue solution is contained in its own tank in a vehicle. It’s injected into the diesel exhaust gas using a dosing control system. Under the effect of the heat in the exhaust gases, the urea in AdBlue decomposes to ammonia. In the SCR, the ammonia reacts with the nitrogen oxides to form nitrogen and water vapour. These compounds are non-polluting and are already present in the atmosphere.

Tips for troubleshooting

  •  Unsure if you need AdBlue? If you don't have a separate tank for AdBlue, then you don't need it.
  • AdBlue is not a fuel additive. You must not mix AdBlue with diesel. AdBlue, like other diesel emission cleaners, must not be put directly into a diesel tank as this can seriously damage the vehicle.
  • The location of the AdBlue tank filler pipe will vary by vehicle manufacturer, so be sure to follow the manufacturer's instructions when using AdBlue.
  • Look for the dedicated AdBlue pumps at truck stops that offer the product. Make sure you choose an AdBlue pump number when you purchase and be sure your AdBlue tank is on the side closest to the AdBlue pump.
  • Make sure your vehicle's AdBlue tank has a magnet installed in the AdBlue filler to enable the AdBlue to be dispensed. Z and Caltex AdBlue dispenser nozzles do not have magnets fitted to avoid accidental filling in vehicles that do not require AdBlue.
  • Take care to wear gloves when handling AdBlue. While it belongs to the lowest water pollution hazard category, AdBlue is a skin irritant and a corrosive liquid that can cause injury if it touches the skin, eyes or respiratory organs.
  • AdBlue damages surfaces such as painted vehicle parts, plastic, items of clothing and carpets. Spilt AdBlue should be removed as quickly as possible using a damp cloth and plenty of cold water. If the mixture is spilt, wash the area immediately as it can be slippery and may cause structural or staining problems with brick or concrete surfaces.
  • Keep all refilling equipment free of dirt and dust. Avoid mixing AdBlue with diesel fuel, and do not use it if it is contaminated with water or fuel of any kind.
