Why is the fuel consumption of the Sylphy getting higher and higher?

[TessaLee]

The reasons for the increasing fuel consumption of the Sylphy are as follows: 1. Insufficient tire pressure and tire wear: Insufficient or low tire pressure increases friction between the tires and the ground, leading to greater resistance and higher fuel consumption. Severe tire wear often causes slipping, which also increases fuel consumption. 2. Pay attention to fuel quality: Regularly clean carbon deposits. 3. Other faults: If the average fuel consumption increases, consider whether there are faults in the car, such as excessive carbon deposits in the engine, damaged oxygen sensors, long overdue replacement of the 'three filters', issues with certain engine control units, or insufficient tire pressure. These factors can all lead to a sudden increase in fuel consumption.
