What does AdBlue do?


AdBlue is composed of Deionised water and a non-toxic mixture of Urea. It acts as Selective Catalytic Reduction (SCR) technology to decrease harmful emissions of nitrogen oxides from diesel vehicles to meet emission standards. It usually cuts down the harmful mono-nitrogen oxides in diesel exhaust. As it is a water-based urea solution and not flammable, so it’s really safe.

What if I have added Adblue in fuel tank?

Suppose the unfortunate situation arises that a driver has added AdBlue in the diesel tank. Do not start the engine as this will circulate the fluid around the vehicle’s fuel system. AdBlue is not compatible with many metals and materials that make up the internals of the fuel system. This system includes cast iron, steel, brass, aluminum, and zinc, so it can corrode this pipework and components. This can cost thousands of pounds worth of damage, not to mention the loss of use of the vehicle until the tank is drained and all repairs have been carried out. You need to get a professional to drain the tank and flush out the system before starting the vehicle.

How to Avoid Adblue in fuel tank?

To help avoid confusion, a lot of vehicles have a blue fill cap for the AdBlue tank and black, red, or green for diesel, and sometimes on larger vehicles such as HGVs. The AdBlue and diesel fill points are positioned quite far away from each other. However, this isn’t foolproof, and a driver is mistakenly putting AdBlue in diesel tank can have disastrous consequences.

Generally speaking, accidentally filling diesel into your AdBlue tank is unlikely as the AdBlue filler cap is designed for a smaller spout nozzle (19mm), making it impossible for larger diameter diesel nozzles to fit. The other way round, however, has become a common problem amongst drivers of vehicles with new SCR systems and causes costly damage.
