AHHHH I'm not in math class right now. Dont make me do math now! I would say it probably uses no more than 1 gallon for every 5 miles, and that is a extremely high guess. The heat doesnt put any load on the engine, the a/c does. The heater runs off of the hot coolant(who ever said TV doesnt teach you anything is an asshat ) that is why you have to wait for the car to warm up before you turn it on. Otherwise it will blow cold air at you. The a/c runs off the compressor witch is belt driven from the engine.

In fact, your driving habits will play a much larger role in determining fuel consumption than your air conditioning will. I personally don't notice any difference in my fuel economy with or without the A/C on . . . my Civic Si pretty consistently does 28-30mpg combined.

Also, using the heater does not affect fuel economy whatsoever. Using the air conditioning potentially can, because it is belt driven and therefore is a parasitic drag on the engine when it is engaged.

Fuel consumption is not determined by throttle position alone. There are many more factors - one particularly major factor being RPM - that play a role.

Running the heater if anything will give you more power ,because its like turning on second rad. That will make your engine cooler giver you more power.

As for the AC it will drop your mileage down alittle but a light(or heavy right foot) makes more of a difference.

I get 30-31 mpg highway with the windows down and no AC. I get 29-31 mpg highway with the windows up and AC. I would say that the AC and the windows prpbably cancel out, I just don't like AC unless it is really hot.

They say A/C systems, on average, consume 25%-30% more fuel when running. I would know, my A/C is on everyday and all day. 95* weather isn't nice.

That is definitely bullshit. If that were true, it would mean my mileage would decrease from 30mpg to ~21-23mpg with the A/C on, which it most certainly does not.

I wish i could dyno it, to prove that what seem like a idiot comment is true. Go run with your the heat on, in both my cars there is a noticable power increase. Just remember my butt dyno is very calibrated and yours may not be.

I believe Ricey said it best. Butt dyno tuning your car can cause more damage to it than spending money on real dyno tuning.(somthing along those lines) Moral of the story is..................... DONT butt tune your car.

http://www.nhscc.com/040523.htm

go to that site notice that I am behind the National winner in ESP(Sam Strano) this year by about .8tenths of second and 4ths off of Larry fine in the stock STI. At the time my Street Modified civic had about 3000 grand in it at the time(Very under prepared, didnt even have a LSD).

I spend more time at the limit in month than you have in your entire life. I can feel things other people will never notice. There are certian people on this board that know me and know what i have done for my cars and there.

I dont even know why i have sunk to your level and taken this post off topic.
