Does using air conditioning while the car is running consume more fuel?

[OEmmett]

Using air conditioning while the car is running consumes more fuel because the car's air conditioning system utilizes a portion of the engine's power. As a result, when the air conditioning is in use, it draws power from the engine, leading to increased fuel consumption. However, the exact amount of additional fuel consumption depends on the car's displacement and speed. Additional information: 1. When the air conditioning is turned on, some small-displacement vehicles may experience noticeable power loss. In such cases, avoid pressing the accelerator pedal abruptly and instead accelerate gradually. 2. Regularly check the air conditioning vents. If the vents are blocked, it may lead to unconsciously turning up the air conditioning, which also increases fuel consumption. 3. Always turn off the air conditioning before parking and shutting off the engine after a drive. Otherwise, the air conditioning will automatically start the next time the car is ignited, increasing the engine's load and fuel consumption. The correct method is to turn off the air conditioning about 5 minutes before parking.
