Does Using Car Air Conditioning Consume More Fuel?

Using car air conditioning does consume more fuel because it utilizes a portion of the engine's power. This results in increased fuel consumption, though the exact amount depends on the vehicle's displacement and speed. Here are some related details: 1. When the car air conditioning is turned on, drivers of small-displacement vehicles may notice a significant drop in power. In such cases, avoid abruptly pressing the accelerator and instead gradually increase speed. Regularly inspect the air conditioning vents as well; blocked vents can lead to unconsciously turning up the air conditioning, which also increases fuel consumption. 2. Always turn off the air conditioning before parking and shutting off the engine. Otherwise, the air conditioning will automatically start the next time the engine is ignited, placing additional strain on the engine and increasing fuel consumption. The correct approach is to turn off the air conditioning approximately 5 minutes before parking.
As a car enthusiast, I understand that using the air conditioning does consume more fuel because it requires the engine to power the compressor, leading to additional gasoline consumption. In urban areas with low-speed driving, fuel consumption increases by an average of 10% to 15%, for example, from 7 liters per 100 kilometers to 8 liters. The impact is smaller on highways, around 5%. The compressor consumes the most energy when starting up, so frequent switching on and off is more fuel-intensive. It's recommended to use the air conditioning on hot days but keep it in recirculation mode for better efficiency, or open the windows for ventilation when it's cooler to save fuel.
I drive to and from work every day, and in the summer, when I turn on the air conditioning, the fuel gauge drops rapidly, making it obvious that I'm spending more on gas. Especially in traffic jams, turning on the AC increases the engine load, and you can practically hear the fuel burning away. I've tested it before—not using the AC saves over 1 liter of fuel per 100 kilometers, but to avoid passing out from the heat, I still have to use it. On the highway, opening the windows actually increases wind resistance and burns more fuel, so the AC is the more efficient choice. In short, using the AC during daily driving does consume more fuel, but moderate use can balance comfort and efficiency.
