[Gianna]

There is no strict regulation on the replacement interval, but 4S shops generally recommend replacing the fuel filter every 40,000 kilometers. More information about the fuel filter is as follows: 1. Generally, external fuel filters require replacement every 10,000 to 20,000 kilometers, while integrated fuel pump filters should be replaced every 40,000 kilometers. 2. The main function of the fuel filter is to remove impurities from the gasoline. If the fuel filter is too dirty or clogged, the main symptoms include: slow acceleration response, difficulty starting the car, or even failure to start. Sometimes, it may take 2-5 attempts to ignite the engine. 3. The replacement of the fuel filter must be performed when the engine is cold.
