Will I Conserve My Gas If I Leave The Air Conditioning Off?

Consumer Reports says no (link below).
In reality there might be some savings, as the power to turn the compressor comes from your engine. But you can save a lot more by driving more conservatively, avoiding lots of quick starts and stops.

yes

The wind drag caused by opening your windows will decrease your gas efficiency more than using the air conditioner

Not unless your air conditioner is a gas one.
I have never seen a gas air conditioner in a car before.

Results from various experiments have shown that opening windows leads to an increase of drag resistance. (Another thing that will cause a reduction in mileage)
From most testing that I’ve seen and read, a speed of 45 is the break point for most vehicles. Travel less than 45mph, open windows will save more gas, travel more than 45mph close windows and use the A/C will save more gas. They did a whole experimental show on Mythbusters, where the vehicles were travelling 55mph and showed that the vehicle with the A/C on actually travelled about 40 miles further than the vehicle with the windows opened.
Of course, travel with windows up and No A/C will save the most gas, if you can tolerate the heat.
Even travelling with the A/C on at lower speeds, the gas usage is typically small. Somewhere on the order of 10% fewer miles if you use the A/C as opposed to not using theA/C. My wife and I drive the same car and I don’t use the A/C to save gas. She can’t live with out the A/C on in her car. Her car gets about 26-28 miles per gallon. My car gets 30-32 miles per gallon.
So the savings is only about 3 miles per gallon every 30 miles.
Easiest way to test is run some experiments on your own car

Yes and No
At speeds below 30mph, the window down and A/C off is more fuel efficient
At speeds above 30mpg, the drag from the open window will use more gas then the A/C, so the A/C is more fuel efficient.
The speeds are ballpark figures and vary a bit by vehicle, but overall they should be correct.

The TV show mythbusters did a test on that subject. There was no large difference.
It was episode #22

depends on what kind of air conditioner you have. If it runs on gas than maybe, depending on how much you use it in a day (usually). If it runs on electricity then you wouldnt save gas at all.

yes by turning the ac off you are making the engine work less and cut back on speed change ur air filter and tire pressure

you sure will,my friend. the a/c compressor pulls 8-10 h/p off your engine. that thing sure pulls…and it won’t hurt to cut it off,and keep the engine from getting hot,even though you have a fine cooling system.,especially in the hot summer days….you will tell tell the gas milage if you cut it off.,i know,i’ve tried it….

Gas is the less expensive, and air conditioning is electrical.

yes. au naturale all the way!

Nope, because the open windows creates drag and will make your car have to work harder. Also newer cars have the A/C running almost all the time. Even when you do not turn it on the A/C unit is still spinning because it is spinning off the same drive belt that runs the rest of your car. You will only conserve gas if your windows are up and your a/c is off, but the difference is not as much as you would think.

No, you won’t, especially not at highway speed. The link below actually has some pretty useful info about gas-saving “myths”.

NO, open windows create drag, and it does not use more gas to run the ac, check out the report that was run today on yahoo, it tells you the myths that people believe will save them money when it comes to gas consumption.

NO, not with the windows open u get the best MPG with the windows closed and use A/C on low setting

put your ac on economy.leaving the windows down,then you will have wind drag and hold your car back.you wont notice it yourself,but it will.

You’ll certainly conserve energy. So it’s good! But gas probably isn’t affected by A/C.
Heaters use gas, but A/Cs don’t.

If you’re talking about gas from your butt, then keeping your air conditioning off won’t help. To get rid of the gas, you may want to go to your local drug store (CVS, Walgreens, etc.) and pick up some anti-gas pills. You will need a parent to get them for you. Hope this helps!
