Top 5 symptoms of a bad fuel filter

The types of filters in a car may vary, but they all share a common primary function: eliminating dirt and impurities trying to reach the part connected to the filter. In today’s discussion, we’ll delve into the fuel filter. Its main role is to prevent dirt from reaching the fuel pump, enabling the engine to burn clean gasoline. Proper combustion requires specific ratios of air and fuel, both free from impurities.

In this article, we’ll present the symptoms of a faulty fuel filter, along with the expected lifespan calculated by experts for this filter.

Signs of a bad fuel filter

  • Car’s engine struggle to start
    Facing difficulty starting the car’s engine may occur due to insufficient fuel reaching the combustion chambers, resulting from filter blockage.
  • car stalls in the middle of the road
    Stopping the car suddenly could be due to filter blockage or damage, causing the engine to shut down unexpectedly.
  • Bad smell from exhaust pipe
    A foul odor accompanying a blocked fuel filter indicates the possibility of complete failure.
  • Decrease in car power and torque
    The driver may notice a decrease in the car’s power and torque during driving, as insufficient fuel reaches the combustion chambers, hindering the spark necessary for the combustion process.
  • Noticeable increase in engine noise
    An abnormal increase in engine noise may be observed. The driver might find that the engine produces loud noises inside the cabin, signaling a crucial issue with the fuel filter.

How Often Should I Change My Fuel Filter?

According to experts, the fuel filter should be replaced every 5 years or after covering a distance ranging between 30,000 to 50,000 km (18,000 – 30,000 miles). It should be checked regularly, approximately every 16,000 km. However, these numbers may vary depending on the car, usage, and the type of fuel used, as the quality of the fuel has a clear impact on this issue.

Experts also advise not to ignore these signs and to immediately visit a specialized maintenance center to prevent issues from spreading to other parts, thus avoiding increased maintenance costs. The fuel filter plays a crucial role in protecting the engine from external influences.
