What are the factors that affect a car's fuel consumption?

[VanGia]

Factors that affect a car's fuel consumption include: 1. Issues with spark plugs and high-voltage wires. As the vehicle's usage time extends, abnormalities in the ignition circuit may occur, leading to increased fuel consumption; 2. The degree of tire wear also impacts fuel consumption. Severe tire wear can cause slippage, requiring the engine to output more power, thereby increasing fuel consumption; 3. Some drivers open windows at high speeds to save on air conditioning, but this increases aerodynamic drag, leading to higher fuel consumption. It is recommended to use the car's air conditioning system flexibly.
