AdBlue is a registered trademark for Diesel Exhaust Fluid (DEF). The trademark is owned by the German Association of the Automotive Industry, commonly known in German as Verband der Automobilindustrie (VDA) and they stipulate some additional requirements for licensees related to the storage and distribution of AdBlue.

Yes, Ampol AdBlue 10L containers are fully recyclable.

All AdBlue is manufactured the ISO 22241 international standard and the finished product must comply with tight specifications listed under this standard. On a fundamental level, there should not be a difference between AdBlue manufactured under different VDA licencees.

AdBlue must only be poured into the AdBlue/DEF fill port. It must never be mixed with fuel or be dispensed into the fuel filler. AdBlue is water based and will damage the engine if it is mixed with fuel. If misfuelling does occur, switch off the engine immediately and contact your road assistance provider to arrange for the vehicle to be towed to a service centre.

The AdBlue fill port is a smaller diameter than the diesel fill port to prevent the diesel nozzle from entering the AdBlue filler.

AdBlue is partially alkaline and can damage paintwork if it’s left on the surface. If AdBlue is spilled on the vehicle paintwork, simply wash it off with water and dry the area. 

AdBlue is highly corrosive to aluminium, brass and bare steel and these surfaces should be washed down with water immediately to prevent surface corrosion.

AdBlue is an aqueous solution of urea and demineralised water and the product can freeze if stored below -11.5oC. Vehicles with SCR systems are fitted with tank heaters to ensure the AdBlue flows into the system as required upon startup.

AdBlue is best stored in a sealed container at room temperature. Under these conditions, AdBlue will last for 12 months.

Vehicles that require AdBlue will have a dedicated fill point that is clearly marked as DEF or AdBlue. Passenger vehicles can easily be filled using our handy 10L top up packs. These feature an extended nozzle secured in the top of the pack that is attached to the pack once the cap is unscrewed. The product can then be poured into the AdBlue fill point. Most passenger vehicles will have an AdBlue tank capacity between 12-20 litres.

A fine mist of AdBlue is injected into the exhaust stream where it heats up and splits into Ammonia and Carbon Dioxide. The nitrogen oxide gases in the exhaust react with the ammonia and the catalyst and they are converted into nitrogen gases and water vapour and released into the atmosphere via the tailpipe.

AdBlue is a mixture of 32.5% automotive grade urea and 67.5% demineralised water. Each batch is mixed in a large vessel under controlled conditions and tested for to ensure it meets the specification requirements prior to transfer for bulk storage or for packing into drums, IBCs or small containers.

Typically, a diesel vehicle will consume AdBlue at a rate between 3-6% of diesel use. A 15L AdBlue tank will therefore hold sufficient AdBlue for 250-500 litres of diesel. Depending on the fuel efficiency of the vehicle and the driving behaviour, this could be sufficient for 8,000-10,000km.

Vehicles fitted with Selective Catalytic Reduction (SCR) systems will have a low AdBlue warning light on the dashboard. The AdBlue tank should be refilled before it is fully empty to prevent the vehicle entering into a limp home, low power mode.

AdBlue levels will also usually be checked and topped up as part of the regular vehicle maintenance process. Please consult your vehicle owner’s manual for more specific information on the AdBlue tank capacity and the level at which the warning light will indicate.

To support the growing demand for AdBlue, Ampol has 10L top up packs available at over 330 retail sites nationally. Ampol also has AdBlue at the pump at over 150 truck access sites nationally and we can deliver AdBlue in 210L drums, 1000L IBCs and in bulk to our business customers wherever they are in Australia.

AdBlue is an aqueous solution of urea and water. If the solution is not stored correctly the water can evaporate, leading to crystallisation. Crystallisation in AdBlue can lead to damage of the SCR system. AdBlue should only be decanted from sealed containers or dedicated AdBlue pumps. If using AdBlue from packs, the whole amount should be decanted and not stored. If AdBlue remains in the container, it should be stored at room temperature and the container should be sealed to prevent the evaporation of the water.
