  • When you turn on your A/C in the vehicle, a small clutch on the pully engages and starts making the engine turn the pully. Having the extra load to turn will cause more fuel consumption.
  • Of course, the amount only depends from car to car, but using A/C requires consumption of gasoline.
  • What many people don't realize is that the A/C also runs whenever you use the defroster. Even when it's the dead of winter -10 degrees and the temp knob is all the way to hot, the A/C still engages. The concept is to dry the air before it blows on the windshield.
  • Don't have an answer for you legs! But i learned a lot from your other answers! So Thank You for your Question!
  • In most modern cars it's more efficient to use the A/C instead of rolling down your windows. This was tested by "Mythbusters:" "it is more efficient, on a hot day, to run with the A/C on and windows up than to run with windows down (b/c of increasing car's drag). Computer-based mpg measurements: * 11.7/11.8 with A/C on and windows up * 11.7/11.8 with A/C off and windows up * 11.3 with A/C off and windows down So, according to the computer, it's better to use A/C with windows up."
