Why does a car engine use more fuel with the airconditioning on?

Because it's attached to the engine and uses power when you turn it on. Even if it wasn't attached to the engine, anything in or on a car that takes power in some form will use fuel because ultimately it's the engine that supplies that power.

Does air-con in a car really use your fuel?
If you mean does the A/C cause the engine to use more fuel, the answer is yes and no. In city driving the A/C does indeed cause the engine to use more fuel. On the highway at speed, the engine uses about the same amount of fuel with the A/C on as with the A/C off and windows down. It also depends on the model year of the car. Older cars have A/C compressors that require more power to drive.
