What is AdBlue®?

AdBlue® is a very high purity aqueous urea solution used in selective catalytic reduction. The chemical make-up of the AdBlue® is used to create a reaction with the noxious gases emitted by diesel engines to convert a proportion of the gases into harmless substances.

Do I need AdBlue®?

If your vehicle requires AdBlue® it will have a separate tank, usually with a blue plastic cap labelled AdBlue®, there will also most likely be a gauge in the cab to show how much is in the tank.

Can I get away with not using it?

If your vehicle has been designed to work with AdBlue® then in a word NO. If you run out of AdBlue® your vehicle will warn you of this and may cut the engine power down.

I can buy a kit to remove the need for AdBlue®

Various aftermarket “magic boxes” are available to mimic the presence of AdBlue® but you use these entirely at your own risk, they are illegal and eventually you will be caught and suffer the consequences. Using licenced high quality AdBlue® has proven to be a very reliable system of emission reduction and is the only real answer in the long run.

Does it affect my vehicles engine?

No. AdBlue® is injected into the exhaust and does not physically affect the engine in any way. It is NOT a fuel additive and should NEVER be put into your diesel tank.

Is it safe to handle?

AdBlue® is a non-hazardous product and so is safe to handle. However use of gloves is advised, for more information please see our AdBlue® MSDS.

Is one brand of AdBlue® better than any other?

AdBlue® must firstly be produced under licence from VDA as it is a registered trademark and secondly it must fall within the specification outlined by ISO 22241. So in truth all AdBlue® is the same, providing it falls into the specification all AdBlue® is of equal quality.

I know where I can buy automotive urea solution

AdBlue® is simple to make, it is water and urea mixed together. However getting it to the required quality requires more than just this. AdBlue® is made from very pure demineralised water and urea that is uncoated and produced specifically for the purpose of AdBlue®. Agricultural urea produces a very cloudy solution that may harm your SCR system. Although it is possible to have this form of “AdBlue®” pass an ISO 22241 test it is unlikely that the producer will try and so you have no guarantees of product strength or quality. Again buy this at your own risk, SCR systems can cost thousands to replace, only with genuine AdBlue® can you be sure of its quality.
