As an automotive specialist with years of experience in the industry, I'm here to provide you with accurate and helpful information regarding your query about AdBlue and its compatibility with diesel fuel.

Firstly, it's essential to understand what AdBlue is. AdBlue is a high-purity, non-toxic urea solution that is used in diesel vehicles to reduce harmful nitrogen oxide (NOx) emissions. It's a crucial component in the Selective Catalytic Reduction (SCR) system, which is a technology designed to clean exhaust gases before they are released into the atmosphere. AdBlue is not a fuel but a reagent that, when sprayed into the exhaust stream, reacts with the NOx to form nitrogen and water vapor, both of which are harmless to the environment.

Now, coming to your question about whether you can put AdBlue into your diesel tank, the answer is no, you should not. AdBlue is not a fuel and should never be added to the diesel fuel tank. It has its own separate tank in vehicles equipped with an SCR system. The AdBlue tank is typically smaller than the diesel fuel tank and is situated in a different part of the vehicle.

If you mistakenly add AdBlue to your diesel tank, it can cause several problems. The most immediate concern is that AdBlue is not combustible and will not provide any power to the engine. This means that your vehicle will not run, and you will need to address the issue before you can use your vehicle again.

Moreover, if a significant amount of AdBlue is introduced into the diesel fuel system, it can lead to contamination of the fuel. This contamination can cause damage to the fuel pump, injectors, and other components of the fuel system. It can also lead to the formation of crystals in the fuel, which can clog filters and further impede the fuel system's operation.

In the event that you have mistakenly added AdBlue to your diesel tank, here are the steps you should take:


1. Stop the Vehicle: If you realize the mistake while driving, stop the vehicle immediately to prevent further damage.


2. Do Not Start the Engine: Avoid starting the engine, as this can lead to more severe problems.


3. Contact a Professional: Reach out to a professional mechanic or your vehicle's dealership. They have the necessary tools and expertise to safely drain the diesel tank and flush the fuel system.


4. Drain and Clean: The professional will drain the diesel tank and flush the fuel system to remove the AdBlue and any contaminated diesel fuel.


5. Dispose of the Contents Safely: The contaminated diesel and AdBlue must be disposed of according to local regulations to prevent environmental harm.


6. Refill the Diesel Tank: Once the system is clean, you can refill the diesel tank with fresh diesel fuel.

7.
Check the AdBlue System: Ensure that the AdBlue system is functioning correctly and that there is enough AdBlue in the tank for the SCR system to operate.

8.
Monitor the Vehicle: After the repair, keep an eye on the vehicle's performance and the AdBlue level to ensure everything is working as it should.

In conclusion, AdBlue is a vital component in reducing harmful emissions from diesel vehicles, but it is not a substitute for diesel fuel. Always ensure that AdBlue is added to the correct tank and that diesel fuel is used exclusively in the diesel fuel tank. If you ever have doubts or concerns about your vehicle's fuel system, it's best to consult with a professional.
