What Happens If You Put Too Much AdBlue in a Diesel Car? and How to Fix It Fast

We’ve all been there, rushing to refuel, half-distracted, and then it hits you: you’ve poured AdBlue into your diesel car’s fuel tank. That sinking feeling is no joke. While it’s a common mistake, it’s also one that can lead to serious (and costly) damage if not handled quickly. Wrong Fuel Experts has helped countless drivers in the same situation, providing fast and reliable fuel drain services to get vehicles back on the road safely. So, what exactly happens when AdBlue finds its way into your diesel tank? 

What Is AdBlue and Why Is It Used?

AdBlue is a urea and deionized water liquid. It is applied in the diesel-powered cars of today that have a Selective Catalytic Reduction (SCR) system. Its work is easy to cut the detrimental nitrogen oxide emissions. The car sprays tiny portions of AdBlue in your exhaust gas to clean up what exits your tailpipe. The thing is, however, that in this case, AdBlue does not approach your engine. It has a separate fuel tank of its own. It should not be mixed with diesel fuel; it is like putting water and oil into the same container, they do not mix.

What Happens If You Put AdBlue in a Diesel Car

When AdBlue is spilled into the diesel tank, it reacts with the fuel to form a thick and sticky substance that has the potential to corrode and clog important essential parts of the engine, such as injectors, filters, and the fuel pumps. In case the engine is still not started yet, then you have caught it at the right time; the repair is far easier. However, when the engine is operated on the polluted fuel, the damage may be caused very easily, and a minor mistake would turn out to be an expensive repair. You may see the warning lights flashing, the engine not starting or a funny smell in the fuel system. These are all indicators that the fuel has been tampered with.

What You Should Do Right Away

The most important rule? Do not start the car. At the fuel station, and you are still at the fuel point, switch off the ignition, draw attention to the personnel, and drive the car out to a safe place. Start-up of the engine will draw the contaminated mixture along your fuel lines and injectors, and that is when the real trouble starts.

Next, call Wrong Fuel Experts. Our AdBlue contamination removal and our mobile teams operate 24/7 throughout the UK. One of the technicians will meet you at the location, empty the mixture, rinse the tank, and fill it with clean diesel. Early the next day, you will be up and about the highway in less than an hour, in most cases.

Why You Should Leave It to the Experts

Attempting to resolve an AdBlue contamination problem yourself is only going to complicate it. AdBlue is crystallized in the presence of heat, and even the slightest residue deposited can destroy your injectors or pumps.

Wrong Fuel Experts have professional-level equipment and tested procedures to eliminate all traces of contamination. Our staff is trained, insured, and ready to deal professionally and safely with such situations, to save you time, stress, and money.

The Professional Fuel Drain Process

Here’s how it usually works when you call us:

Our technician will examine your motor vehicle and verify the amount of AdBlue that was put in. Then we safely empty the contaminated mix of fuel using a closed fuel recovery system, and there are no spillages or damage to anything. After the tank has been emptied, we completely run the fuel lines and filters to get any residue out, and then we fill up your tank with clean diesel. Last but not least, we conduct diagnostic tests to ensure that we are well-rounded.

The entire procedure is fast, clean, and it is absolutely safe for your car, not to mention that it is also much cheaper than having the garage service.

Common Mistakes That Lead to AdBlue in Diesel

The majority of the mix-ups occur at the pump, and they occur most often when the AdBlue filler is inserted beside the diesel filler. The other frequent reason is the transportation of AdBlue in the same container as the fuel. It does not seem to be much, but any incorrect container or nozzle will break your tank.

To prevent it in the future, I would always check labels twice and always maintain a separation between AdBlue and fuel containers, and never hurry during refueling. A flash of an eye can save thousands.

How Much Damage Can It Cause?

This will depend on the start of the car. As long as you notice the error before switching the key, it should be corrected by a drain of fuel. However, when the polluted mixture was sprayed into the system, you might have to repair the injectors, filters, or fuel pump. This is why we have to act immediately – the more speedily you act, the less you will suffer.

FAQs

Does a small quantity of AdBlue in diesel harm?

Yes. Even a little of it can begin a chemical reaction that forms crystals and blockages within your fuel system. It is better to have the whole tank emptied by professionals even when a small amount of the tank was put in.

What is the duration of the AdBlue removal process?

Our technicians finish the work in almost one hour in most instances. This involves draining, flushing, replacing with clean diesel, and a full check-up, and then starting the vehicle.

What will occur in case I drive after having added AdBlue?

When using AdBlue-contaminated fuel, it is likely to cause serious damage to injectors, pumps, and filters. The contracts may cost thousands to fix. Pull over the car and dial Wrong Fuel Experts to provide emergency help.
