Putting AdBlue in the diesel fuel tank is one of the most serious wrong fuel incidents. AdBlue is corrosive and can cause catastrophic damage to the fuel system if the engine is started. Do not start the engine under any circumstances and call us immediately.
AdBlue is a corrosive urea-based solution. In the fuel tank, it can crystallise and cause severe damage to the fuel pump, injectors, fuel lines, and other components. The damage can occur very quickly once the engine is started. Do not start the engine. Do not attempt to drain it yourself. Call us immediately on 0330 520 1620.
Follow these steps immediately — acting quickly is critical.
This is absolutely critical. AdBlue is a corrosive fluid that can cause catastrophic damage to the fuel system if the engine is started. Even a small amount of AdBlue in the fuel tank can destroy the fuel pump, injectors, and other components within minutes of the engine running.
If you are still at the petrol station, leave the car at the pump and inform forecourt staff immediately. If you have already driven away, move to a safe location, switch on your hazard lights, and stay clear of traffic.
We will arrange recovery to a specialist garage as quickly as possible. AdBlue in the fuel tank is a serious incident — do not attempt to drive the vehicle or drain it yourself.
AdBlue is corrosive and requires specialist equipment to drain safely. Attempting to drain it yourself can cause additional damage and is dangerous. Leave it to a trained specialist.
AdBlue is a diesel exhaust fluid (DEF) used in modern diesel vehicles with SCR (Selective Catalytic Reduction) systems. It is injected into the exhaust gases to reduce harmful nitrogen oxide (NOx) emissions. It is stored in a separate tank — usually with a blue filler cap — and should never enter the main fuel tank.
AdBlue is a mixture of urea and deionised water. In the fuel tank, it does not mix with diesel and begins to crystallise. These crystals can block the fuel filter and damage the fuel pump and injectors. The corrosive nature of AdBlue also attacks metal components in the fuel system.
If the engine is started with AdBlue in the fuel tank, the contaminated fuel is circulated through the entire fuel system at high pressure. This can cause catastrophic damage within minutes, potentially requiring replacement of the fuel pump, injectors, fuel lines, and other components at a cost of several thousand pounds.
The key message is: do not start the engine under any circumstances if you suspect AdBlue has entered the fuel tank. Call us immediately on 0330 520 1620.
We answer at any hour — early morning, late night, bank holidays. One number, always answered.
AdBlue in the fuel tank requires specialist treatment. We refer you to the right specialists for this type of incident.
