Does Changing the Fuel Filter Save Fuel?
1 Answers
Changing the fuel filter can save fuel. If the fuel filter is severely clogged, you will notice a significant improvement in fuel efficiency after replacement. In daily driving, it is important to develop the habit of regular vehicle maintenance. Whether fuel is saved or not depends not only on the driver's habits but also on the technical condition of the vehicle itself. When the fuel filter becomes heavily contaminated, it can obstruct the fuel supply to the engine. The engine control unit, failing to meet the required air-to-fuel ratio (i.e., the air-fuel ratio), will increase fuel supply to compensate, leading to higher fuel consumption. In such cases, replacing the fuel filter will noticeably reduce fuel consumption, resulting in improved fuel efficiency.
