What are the symptoms of contaminated fuel in a car?
Contaminated fuel can lead to a wide range of performance issues that often appear suddenly after refueling. Common symptoms include engine misfires, hesitation during acceleration, poor fuel economy, hard starting, or the engine failing to start at all. You might also notice a rough idle, increased exhaust smoke, or unusual knocking or pinging sounds from the engine. In some cases, the check engine light will illuminate, or your vehicle may go into limp mode to protect critical components. These issues occur because contaminated fuel disrupts the combustion process, clogs fuel injectors, and affects the efficiency of the fuel system. If left unresolved, it can lead to expensive repairs, including damage to the fuel pump or engine internals.
What causes fuel contamination?
Fuel contamination can occur in several ways, and it often starts at the pump or during fuel storage. One of the most common causes is water ingress—usually from condensation in underground fuel tanks or during transportation. Water in fuel can cause rust, microbial growth (known as diesel bug), and poor combustion. Another major cause is the accidental mixing of fuels, such as putting petrol in a diesel car or vice versa, which can damage fuel system components quickly. Contaminants like dirt, sludge, or even metal shavings can enter the tank from corroded fuel tanks or dirty jerry cans. In rare cases, poor-quality or adulterated fuel can be to blame, especially if bought from unreliable sources. Regardless of the cause, contaminated fuel poses serious risks and should be addressed immediately.
How is contaminated fuel removed from a vehicle?
The process of removing contaminated fuel typically involves draining the fuel tank completely and flushing the entire fuel system. This includes removing any residue or water from the tank, inspecting and cleaning the fuel lines, and replacing the fuel filter. In cases where the wrong fuel type was added, the mechanic may also need to check the injectors, spark plugs, and engine internals for damage or carbon buildup. For diesel vehicles, special attention is given to the fuel rail and injectors, as these components are sensitive and prone to damage from even small amounts of contamination. Once the system is clean, new fuel is added, and the vehicle is started and monitored to ensure proper operation. In more severe cases, further diagnostics may be needed to confirm that no long-term damage has occurred.
