Not a lot but it uses engine power to turn and therefore more gas is needed than normal to maintain a certain speed.

Re: Does Air Conditioning waste alot of Gas? (99MilanoRedSi)
I've heard it stated several times, but haven't researched as a fact, that in a modern car your highway mileage will be better with the a/c on and the windows up that it will with the a/c off and windows down, due to the increased drag of the open windows. I may do some web searching to see if I can find any support for this.

you lose 3 or 4 mpg. i have also heard that you are better of with the AC on and windows up versus ac off and windows down. aerodynamics. so it costs 1/2 a cent more per mile for AC. what a bargain!!

A/C only wastes gas when it is turned on correct? does anyone know how much the A/C unit weights all together, on a 99 Civic Hatchback?

Re: Does Air Conditioning waste alot of Gas? (Project CTR)
all of the AC equipment weights at most 40 pounds. So that right there costs you 1/4 MPG. 12K miles a years and you spend an extra 4$ for THREE gallons of gas extra. But since you are "saving" money not having that weight to haul around you lose 3 MPG having the windows down. That costs you an extra 44 gallons of gas. 50$ per year.
So, at the end of the year you have sweated and had the windows down, devalued your car by $1,000, commited a federal offense releasing refrigerant into the atmosphere, all to spend 46$. Not to mention the wear and tear on your car's interior with all the dirt and wind buffeting the headliner.
Just use the AC please.

yes and no...Your ac robs you of power, but if you don't speed and just go a little slower then you are fine, but if you leave the window down and run the **** out of the car, then the drag hurts you more, kind of ironic huh?

I've got enough statistics on my 4Door 4x4 Tahoe to prove that the AC ON gets about 0.8 to 1.2 BETTER MPG at a 75 mph true indicated cruise speed.
