Fuel filters cannot be left unchanged. As one of the important items in car maintenance, fuel filters play a crucial role in engine operation. Here is a detailed introduction: Classification of fuel filters: According to the type of fuel, they can be divided into gasoline filters and diesel filters, which are a type of wear-prone parts that require regular cleaning and replacement. Replacement cycle of fuel filters: Under normal usage conditions, fuel filters must be replaced every 30,000 kilometers. If the fuel contains a large amount of impurities, the replacement interval should be shortened accordingly. Generally, it is recommended to replace them every 20,000 kilometers. The optimal replacement timing can be referred to in the vehicle's user manual.
