What are the main reasons for high fuel consumption in cars?

The main reasons for high fuel consumption in cars are: 1. Poor driving habits of the driver; 2. Wear and tear of engine-related components; 3. Malfunction of the car's oxygen sensor; 4. Low tire pressure or severe tire wear; 5. Incorrect fuel grade, poor fuel flow, or improper spark plug gap. Precautions for refueling include: 1. Use automotive gasoline; inappropriate fuel entering the fuel system may damage the fuel system and engine; 2. Do not use gasoline containing methanol or alcohol; 3. Avoid spilling fuel on the paint surface to prevent damage; 4. If the fuel tank door is frozen and cannot be opened, gently push or tap the fuel tank door to remove ice and open it; 5. Prevent excessive fuel pressure from causing spraying; 6. Insert the fuel nozzle deep into the fuel tank to avoid fuel overflow or splashing, which could lead to fire and explosion.
I think one major reason for high car fuel consumption is aggressive driving habits. When I drive, if I frequently accelerate rapidly, stomp on the gas pedal at startup, or often brake suddenly, fuel consumption skyrockets, especially in stop-and-go traffic which wastes even more fuel. Speeding on highways increases wind resistance and also consumes more fuel—once the speed exceeds 100 km/h, you can clearly see the fuel gauge dropping. Additionally, incorrect gear selection, such as driving at low speeds in high gear with an automatic transmission or failing to shift gears in time with a manual transmission, forces the engine to consume more fuel. It's recommended to maintain smooth driving, accelerate and decelerate gently, and drive around 60 km/h in the city for optimal fuel efficiency.
