AdBlue in Fuel Tank

AdBlue is usually misunderstood as a fuel additive when it is actually an exhaust fluid that should never be mixed with diesel. AdBlue has its own tank and is located completely separately from your vehicle’s fuel tank. To help avoid confusion, a lot of vehicles have a blue fill cap for the AdBlue tank and black and 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 mistakenly putting AdBlue into the diesel tank can have disastrous consequences. For your comfort, we provide 24/7 on-the-spot drainage service with reasonable charges and as minimal time as possible.
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. If your vehicle’s fuel system is polluted with AdBlue the fuel tank will need to be drained and the fuel system flushed and cleaned. If driven it can often result in expensive repair costs with the need to replace numerous parts and components. Our latest vehicles are equipped to drain all makes and models to help customers who have mistakenly put AdBlue in their vehicle’s fuel tanks.
If 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 including cast iron, steel, brass, aluminum and zinc, so it can corrode the pipework and components. This can cost thousands of pound 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.
