What are the reasons for increased car fuel consumption?

[DiAlex]

Reasons for increased car fuel consumption: 1. Engine carbon deposits: During long-term operation, gasoline inevitably produces carbon deposits and sludge during combustion. If these deposits are not cleaned in time, they will lead to increased fuel consumption; 2. Spark plug failure: If damaged, it will reduce ignition energy and cause uneven combustion of the air-fuel mixture, resulting in slower acceleration and increased fuel consumption; 3. Abnormal tire pressure: Improper tire pressure can also affect fuel consumption. When the tire pressure is too low or the tread is severely worn, the contact area between the tire and the road surface increases, leading to greater friction, increased rolling resistance, and naturally higher fuel consumption; 4. Poor fuel injector atomization: This situation may be caused by clogged fuel injectors, significantly affecting their performance, which also leads to increased fuel consumption.
