Whether the air conditioning drained petrol was an ongoing argument between this husband and wife. Luckily, we had a Professor of Robotics call in to settle the dispute.
Does having the air conditioning on in the car use more petrol?

Answer: It takes quite a lot of power to compress the coolant fluid in the air conditioning, you have a big, heavy compressor and an electric clutch to engage it. This therefore uses up more energy. There is a 2% increase in the use of fuel when you turn on the air conditioning.
