yes it’s true. The engine has to work harder when the A/C is on.
I have tired it both ways with just a small improvement on mileage with the ac off…. But if you see me driving around you will notice my windows are up and the ac is blowing full blast…Stay kool while you can…:
That’s correct. The engine uses more power when using the AC, so it uses more gas for that purpose.
While it does not say anything about the AC here are some good tips for saving gas.
That is correct but it wastes more gas if you roll down the windows
Yes, using the AC makes the engine consume more gas, because it is working harder. It is almost as if you were accelarating a little harder or accelarating all the time- but not really that bad. It may however reduce consumption 3-7% depending on how high the AC is.
They say that having the windows down can increase gas mileage by reducing the streamlining of the air (thus nullifying no A/C), but to the extent I don’t know.
That’s actually not true – Having the windows up helps save gas. It only saves gas if you don’t have an a/c unit in your vehicle. This reduces the weight and increases gas mileage.
Of course its true, the A/C compressor uses power from the motor.
It varies from car to car, but its about 8% more fuel with A/C on.
That’s true. The air conditioner taxes your engine, so if you don’t use it you will save some gas. How much gas you save depends on your driving habits and the type of engine you have in your car. If you do mostly freeway driving and you have a big V-6 or a V-8 under the hood, driving without air won’t save much gas. However, if you have any type of 4-cylinder engine under the hood you’ll save more gas, especially if you do a lot of city driving (could be as much as 5 MPG in the city by shutting off the A/C).
Absoluteley. The fan that just blows aout air to you is electrical, but the system that controls the A/C is powered by an additional motor that runs on the same gas that is used by the engine. So, the more you use your A/C the more gas you will consume.
What some people do is that if your car is really hot, they’ll turn it on for a few minutes, and then shut it off and just roll down the windows. Your best bet will be to park in the shade and you should be fine.
It depends on how fast you are going. On the highway it really doesn’t matter but if you’re driving around town it does save gas to keep the windows down instead of turning on the air.
“Using air conditioning wastes gas?
Not always, according to Consumer Reports. If you’re going more than 40 miles per hour, it’s probably better to have the air conditioning on. But if you’re driving around town at 30 miles per hour, keeping the windows down will be your best bet.”
Yes It is True Also Don’t Bring Alot Of Weight In The Car.
This is only partly true. It would save gas to turn off AC but you would have to leave your windows up. If you roll the windows down you cause resistance which causes your engine to work just as hard.
Oh yea…..Thats a given!!
The extra load the compressor (when engaged) puts on the engine makes you use more gas.
To see the difference…sit idle, and look at your tachometer (RPMs) kick on the AC and watch your RPMs drop by several hundred. If you want to bring your engine back up to the original RPM you have to press the gas slightly, THUS using more gas than sitting idle. right?
BUT, keep in mind, at highway speeds its better to run the AC instead of having your windows down. If you have your front windows open, the back part of the car acts like a parachute, if you will, and holds your car back, thus requiring you to press deeper on the gas pedal to acheive the same speed.
Yes, but you can die of heat stroke.
No,,, in newer cars tests have shown that opening the windows causes more “arodynamic drag”, using more gas, than running the AC.
So it depends actually on the age of your vehicle.
Yes, but not if you open the windows, it may equal out.
With modern cars, using the AC results in little or no change in fuel economy.
With older cars, depends on the design and the transmission.
I had a Neon which returned over 40 mpg in the summer when I rolled down the window and used my arm as an aerodynamic tool.
For most older cars fuel economy goes down with AC usage.
not much but you do in city driving…but on the highway it is the same either way…
on the highway your areodynamics are involved more…so with your windows up and air on you have better dynamic…
with your windows down on the highway you cause more drag on your car…
hope that helps
To answer the question strictly as you asked it, yes, AC uses gas. However, if you want ventilation, according to a MythBusters episode (Discovery channel), the cross-over point is 50mph. Above that speed, the drag on the car created by open windows makes the car less efficient and so you should close the windows and turn on the AC. Below 50mph, the AC becomes the factor adversely affecting mileage and you should turn off the AC and open the windows.
yes it is true. the show mythbusters did an episode on it.
ive heard that but ive also heard it uses as much gas with the widows down too cause the car fights more against the wind
I work for a major automobile corp. and we have done studies involving the use of the a/c and rolling the windows down. From our results we concluded that it decreased the fuel economy when the windows were rolled down, due to the wind drag moving through the vehicle. You can actually save fuel if you run your a/c.
Yes this is true in all vehicles. But if you open the windows you will also have drag which will reduce your gas. So if you want to stay cool run the ac. You can do an experiment yourself by filling up zeroing your trip odometer and running your ac while you drive everytime you drive until your empty. Then fill up and get your mileage. Then reset the trip odometer and turn off the ac and drive with the windows open everytime you drive until your empty. Do the math and you will have the answer for your particular car. Have fun!
THATS.NOT.TRUE.
