Myth: Using The Air Conditioner Uses More Gas
Some drivers avoid air conditioning to save fuel, but using the AC only slightly increases fuel consumption. Although AC uses engine power, the impact on fuel consumption varies by vehicle.

The savings from shutting off the AC might only amount to a few miles per gallon, and during extreme temperatures, comfort often outweighs minimal fuel economy gains. So, while there’s truth in the myth, the difference may be less impactful than expected.
