What does 12 fuel consumption mean?

12 fuel consumption refers to the amount of fuel consumed by a car when driving 100 kilometers at a constant speed. 12 fuel means that the car consumes 12 liters of fuel per 100 kilometers. Observing instantaneous fuel consumption is of great significance for understanding the fuel consumption of the engine under different conditions. You should consider whether your driving habits are too aggressive, such as emergency braking, fluctuating speeds, or seizing every gap, as these driving habits can also increase the car's fuel consumption. By observing instantaneous fuel consumption, you can understand the fuel consumption when the vehicle is stationary and the engine is idling; through instantaneous fuel consumption, you can understand the fuel consumption per 100 kilometers at different speeds, thereby finding the vehicle's economical speed; for some vehicles with computer-controlled fuel injection, instantaneous fuel consumption can show that the fuel consumption is "0" when coasting in gear (the fuel injector stops injecting fuel). If it is not a sudden increase in instantaneous fuel consumption but an increase in average fuel consumption, you should consider whether the car has a malfunction, such as excessive carbon deposits in the engine, a damaged oxygen sensor, long-unreplaced "three filters," a problem with a certain engine control unit, or insufficient tire pressure. These can all cause a sudden increase in car fuel consumption, accompanied by a decrease in power performance and changes in exhaust color. If it is a car-related issue, it is recommended that the owner go to a 4S shop for inspection and repair. Regular maintenance can also keep the car in good working condition.
12 fuel consumption means the car burns 12 liters of gasoline for every 100 kilometers driven. I've also experienced high fuel consumption when driving myself, and found that this value is influenced by many factors. For example, fuel consumption in city traffic jams is significantly higher than on highways, especially when using air conditioning or carrying heavy loads. If you tend to accelerate and brake sharply during normal driving, or if the engine operates at low gears for extended periods, it can also increase fuel consumption. For my old sedan, the actual fuel consumption is between 8-10 liters, so 12 is indeed a bit high. It might be necessary to check tire pressure or spark plug condition.
