Is it important which AdBlue® you use?

It makes no difference which AdBlue® you use in the automobile industry. AdBlue®is the name of the product however customers can purchase different branded AdBlue® provided the manufacturer produced the AdBlue® following ISO 22241 standards. It all works the same regardless of whose brand it is marketed under. Just like diesel/petrol which are the name of the product however customers can fill up diesel/petrol from different branded oil companies provided the fuel meet the standards.

That being said, it is essential to ensure you get the right AdBlue® for vehicles, with the ISO 22241 label (including ISO-22241-1, ISO-22241-2, ISO-22241-3), to avoid damaging the catalytic converter in your vehicle exhaust, which is a costly component to replace. It is crucial to purchase the highest quality AdBlue® from AirNoxblue/AirNox to ensure that your vehicle is in safe hands.

Otherwise, low-quality AdBlue® will not fulfil the purpose and may also damage your vehicle. Hence, it is very important to choose a reliable AdBlue® supplier like AirNox.
