What Happens When AdBlue in Fuel Tank by Mistake
AdBlue is a liquid used in diesel vehicles to reduce harmful emissions. It is stored in a separate tank and injected into the exhaust system, not the fuel tank. When AdBlue is mistakenly added to the fuel tank, it mixes with diesel fuel and causes several problems:
Corrosion of fuel system components: AdBlue contains urea and water, which can corrode metal parts inside the fuel system.
Fuel contamination: The mixture can clog fuel filters and damage the fuel pump.
Engine performance issues: Contaminated fuel can cause misfires, stalling, or failure to start.
Potential long-term damage: If not addressed quickly, the engine and fuel system may suffer permanent damage.
Understanding these risks highlights why immediate action is necessary.
Immediate Steps to Take After Misfuelling
If you realize you have put AdBlue in your fuel tank, follow these steps without delay:
Do not start the engine
Starting the engine will circulate the contaminated fuel, increasing damage.
