How much MORE GAS does your AC use?

#ac #consumption #fuel

In this video, I will be using my android OBD2 unit to monitor my fuel flow at idle, and at idle with my ac on in the car. The objective of this video is to determine how muchadditional fuel is being expended to run the ac unit in my car, and finally, how much more I am spending to keep myself cool on these hot days.

My dad and I once drove to Vegas (5hours) and he didn’t turn on the ac to save gas this man was literally cooking me to save like 5 bucks😂

I don't care if gas goes to $10 a gallon, that cold air equals gold on a 90+ degree day!

I done an actual test using everyday driving conditions. Just driving back and forth to work. A full tank of gas without the AC got me 360 miles before the gas light came on. A full tank of gas withe the AC running got me 335 miles before the gas light came on. so it does make a small difference but not anything significant. The car i tested this with is a 2013 Ford Focus with a 2.0 liter 4 cylinder with an automatic transmission.

I learned that it also depends on the car because each car is built different. The configurations changes how much gas you use

I mostly sleep for about 4-5 hours in the car in between shifts, instead of driving an hour back and forth from home half-asleep. And with weather in SoCal right now in the summer peaking at triple digits, I would go with AC instead of suffering a heat stroke any day.

Thanks for the video.

To get an even better 20% gas efficiency I removed and bypassed my AC compressor completely and fitted a shorter belt for less pulley friction on the crank and 20kg less vehicle weight ! On a warm day I still keep my windows up and just use a separate 12V fan I stuck on the dash !

Finally someone doing a real test

Thanks a lot Subbed

nice video, nice head unit. I'm not convinced that a/c uses more gas, and the reason is because the only reason your fuel consumption increases is because the rpm increase. your vehicle (as many of our vehicles) has many miles so that load has more impact than a new vehicle would. for example, go rent or test drive a brand new vehicle and turn the a/c on max & you will hardly notice any difference. so basically, it's the increase in rpm not necessarily the a/c. if you slightly push the gas pedal so that it raises the rpm to 800 (with the a/c off), you will see the same 1cent/gallon increase. Also, another reason I'm not convinced is because the a/c compressor is constantly spinning with the belt no matter if your using a/c or not. in addition, you may have that spike in engine load & increase in rpm when you first turn the a/c on max however after 30 - 60 seconds it will level out and your fuel consumption will go bck to normal. at 2:25 you turned the air off and back on to show that it gives a constant increase, however most modern cars have thermostat to monitor interior temp and the fact that you didn't let your car a/c run long enough to cool the cabin is why it will wrk hard at first start to cool the cabin.

Are ee talking about AC on windows up or down in a parking lot? Or while driving? Because if you are driving windows down...you need to consider air drag....

Great video Steven,
I never thought to use all those gauges in such away.
How much more does the load go up if you turned the fan all the way up?

[tylercroft]

Nice vid! Always wondered how much the AC was actually using. Not worth it to me tho lol, rather just drive with the windows down.

This matches the results Tech Ingredients found idling in the winter, so that basically proves it lol - regardless of weather, you're looking at about 1/3 gallon per hour idling a typical car with heat/AC on.

That's significantly cheaper than I expected, so I'll finally stop worrying about the cost of this when I do it.

I think that test was done at idle, if so, I think your numbers will be a fair amount different under "driving" conditions.

I like enjoying the free sauna sometimes, gotta love summer.

[AngelCintiaRockgirl]

20 to 27 is almost nothing

80 cents an hour is hardly a factor. Also, if you don't run your A. C. regularly for a long, long time your seals will dry inside the unit and it won't work anymore, and it will leak the coolant into the air/atmosphere and add to the environmental consequences. Also, this guy should run that efficiency/flow/load test on the freeway with windows down. A. C. should win, unless you have a bad A. C. compressor.

Irony I'm sitting in my Evo x running ac to figure this out and this is the first video that comes up when I ask "does ac use more gas" 😂 crazyy

[preachffxi]

A full tank how much $ wasted having ac on .. about a dollar?

[daileenemorales]

Tnhks. I also would like the test done in a highway vs city
I feel like in highway it doesn’t make a difference since the the car is already running in high rev

[kelaxy]

Now you need to do it while driving 30 50 and 70 mph to see how much difference there is while driving. ✌️

This test was done on idle, what about a moving car driving around? 😢
