How much higher is the fuel consumption when changing from 235 to 245?

[LaEdward]

Changing from 235 to 245 increases fuel consumption by about 6 units. Here are some methods to reduce fuel consumption: 1. Close the windows: Driving with windows open increases wind resistance. The greater the wind resistance, the more resistance the car encounters, requiring more power and thus increasing fuel consumption. 2. Regularly maintain the vehicle or perform inspections: Timely oil changes can reduce carbon deposits (carbon deposits can cause uneven ignition, sluggish acceleration, increased fuel consumption, and in severe cases, even cylinder misfires). 3. Replace fluids on time: If the oil is not replaced promptly, the car's shaking will become more noticeable, and fuel consumption will also increase.
