What happens if I accidentally put AdBlue in diesel tank in Bedfordshire?

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 on many HGVs the AdBlue™ and diesel fill points are positioned quite far away from each other. However this isn’t fool proof and a driver mistakenly putting AdBlue™ into the diesel tank can have disastrous consequences.

If the unfortunate situation arises that a driver has added AdBlue™ in the diesel tank, this can cause costly damage. AdBlue™ is not compatible with many materials so it can corrode the pipework and components in the fuel system. This can cost thousands of pound worth of damage, not to mention the loss of use of the vehicle until a professional gas drained the tank, flushed out the system and carried out all repairs.

In order to meet Emission Standards, diesel vehicles need to reduce their emissions down to a certain level depending upon the engine size. In response to this, exhaust technology has been introduced that uses a fluid known as AdBlue™ (DEF) to reduce the Nitrous Oxides present in emissions.


AdBlue™ is commonly mistaken as a fuel additive, when in fact it should not be mixed with diesel at all. Whereas diesel is for the running of the engine, AdBlue™ is designed for the SCR system in the vehicle exhaust and therefore is dispensed into a completely different tank to the diesel.

AdBlue is injected into the exhaust stream of diesel engines to reduce the amount of NOx emitted, helping them to meet emissions regulations. Without AdBlue, diesel engines will produce more pollutants than allowed by law, and will fail emissions tests. Please check the owner's manual.

What do I do if I have put AdBlue in diesel tank in Bedfordshire?


If you added adblue in diesel tank, it is recommended to not start the car or move it if it could be remedied! AdBlue solution is more corrosive and heavier than diesel and can fall below the level of the diesel tank. It can then enter the diesel fuel system rapidly, causing much damage within a short time. The only way to stop this is to flush the diesel tank to the bare minimum, then replenish it by using clean diesel.

  • DO NOT turn on your vehicle engine - this will circulate the AdBlue™ round the vehicle

Adding AdBlue (Diesel Exhaust Fluid) directly to the fuel tank is not the correct procedure and can lead to serious engine damage and poor vehicle performance. AdBlue is specifically designed to be used in the Selective Catalytic Reduction (SCR) system of diesel vehicles to reduce emissions of nitrogen oxides (NOx).

Adding AdBlue to the fuel tank can result in the following issues:

  1. Engine Damage: AdBlue is not formulated to be burned as fuel. Adding it to the fuel tank can damage engine components, such as fuel injectors, pumps, and other sensitive parts.

  2. Poor Combustion: The mixture of AdBlue with diesel fuel can negatively impact the combustion process, leading to incomplete burning and reduced engine efficiency.

  3. Clogging: AdBlue is a water-based solution that contains urea. If it is added to the fuel tank, it can cause clogs in the fuel system and filters.

  4. Increased Emissions: Adding AdBlue to the fuel tank can disrupt the proper functioning of the vehicle's emission control systems, leading to increased emissions of harmful pollutants.

To avoid these issues, it's crucial to only add AdBlue to the designated AdBlue tank in vehicles equipped with SCR systems. The AdBlue tank is separate from the diesel fuel tank, and there is typically a specific filler neck or cap for refilling AdBlue. Always refer to your vehicle's owner's manual for guidance on the correct usage of AdBlue and follow the manufacturer's recommendations to ensure the proper functioning of your vehicle's emission control systems and engine performance.

AdBlue is a water-based fluid, uses specifically in diesel vehicles equipped with Selective Catalytic Reduction (SCR) technology, and it is strictly not fuel or additive. It is simply a diesel exhaust fluid (DEF) to convert harmful gases into water and nitrogen.

AdBlue is corrosive liquid and has detergent and crystallization properties. This can have various devastating effects on your car’s engine and fuel assembly, such as;


1. Damaging the fuel lines, and especially the fuel pump by clogging the small inlets and valves.


2. As it gets crystallized, it can clog and damage the fuel filter, and fuel injectors as well. This can hamper the performance and fuel economy of the car.


3. As it decomposes the lubricants and other protective layers inside the engine, it can increase friction and heat generation, damaging the engine beyond repair.

To avoid these problems, simply call us anytime and get your fuel system drained professionally and environmentally in Bedfordshire.
