No, child, you are the lost mileage. Enjoy prison.

>blazing hot summer
>have to choose between not dying of a heatstroke or being able to climb uphills

Jokes on you, air conditioning demon, my AC doesn't even work.

>>28910851
Do your windows not roll down or something?

>>28910798
A/C really doesn't drag much unless it's blasting like crazy, my Honda cruises fine with the fan speed and temp on minimum, but if you blast it, the car will only do 60 mph with as much throttle needed to normally go 80 mph, I think the condenser get heatsoaked or something and it causes drag, because my A/C is super cold, and the heat has to go somewhere, makes the engine bay scorching hot when I blast it.

>>28910851
yuro problems, don't wanna know

>>28911147
Your fucking fan speed has nothing to do with fuel consumption dumb ass. Your ac works off your crankshaft not your electric fan

>>28911176
I know, but all that heat that is being transferred into the evap core when you blast the shit out of it at full fan speed, then into the condenser which makes it it seems to cause higher A/C pressure, which means more compressor drag, and why the car becomes an inefficient snail that you're practically slamming on the gas and getting barely anything out of.

>>28910798
i believe 55 mph and above is when it's more efficient to just use AC
also if engine braking turn on the AC for a bit more lol

>>28911211
>if engine braking turn on the AC for a bit more lol
Kek it actually works, one time I thew it into neutral for some rev bombs, put it back in drive and it was like someone hit the brakes when it went back into gear with the compressor engaged.

i dont really notice a drop.

>>28911216
Same, really depends on the vehicle, if you've got an engine that doesn't do much work at low rpm, A/C on will kill your power.

>>28910798
AC in new cars is actually really efficient
Rolling down your windows above 50mph ruins your gas mileage more in modern cars than running the AC

>>28911222
The ECON made of newer cars is really quite amazing at not running the A/C to the point where the car is struggling to move, my car is old and dumb where the A/C is amazing but if you leave it blasting becomes inefficient.

I'm in a car from '84 and I don't notice any meaningful drop in mileage with the AC on. Is OP driving an electric car or something?

>>28911309
He's probably a 4 cylinder bro, they get kinda slow when the A/C is on, that's why a lot of economy cars with early 4 bangers didn't even come with A/C

Economy loss is about 5% to 7%. I live in Australia and I don't really utilize the aircon until it's REALLY hot. Then I run it full blast until the car is cooled down and then run it on the lowest fan setting to maintain temp.

Not a big fan of auto modern dual climate control. Give me a temperature control and fan control any day.

Simple as.

>>28911319
>Then I run it full blast until the car is cooled down and then run it on the lowest fan setting to maintain temp
Based, that's how you're supposed to do it, cars have protection in place to click off the compressor so that the evaporator doesn't get so cold it freezes and causes a problem, but they don't have anything to slow the fan down when the condenser is condensing a little too much heat and causing massive A/C drag.

>>28911338

>but they don't have anything to slow the fan down when the condenser is condensing a little too much heat and causing massive A/C drag.

Yeah I fuck around and do my own AC gassing and servicing. The more air going through the condenser, the more efficient your AC is going to be.

I set my pressures at idle and you'll get one temperature out of the dash, once you jump in the car and go for a drive you'll get temps way colder coming out of the dash. This is on a 40*C ambient day.

>>28910798
>having such little displacement that it even matters

>>28911313
I have an almost 20 year old 4 cylinder shitbox and I don't really feel it when the A/C kicks in, only if I turn it on when parked I see idle rev go up a bit.

In my maverick hybrid the AC reduces mpg from like 40 to 37, there's no drag or anything associated with the AC but the engine will kick in more often to charge the hybrid battery.

It's better to have the windows up and use the AC by far above like 45mph. Having the windows closed lets you use the stereo at lower volume which uses less power from the hybrid battery... Since everything 12v is charged by the hybrid battery with no alternator.

>>28910798
Because I dont drive an underpowered shitbox I see no noticeable change in fuel economy when using ac

Anyone else feel like automotive air conditioning doesn't actually keep you cool if you are stilling getting blasted by the sun?

>>28911666

Skill issue. Your AC should be shitting out at 2 to 4*C in Australia. Otherwise you may as well piss on yourself to get cooler, you weak cunt.

Jokes on you. My car doesn't even have an A/C. I always drive with the fan on though because I've been told it's better for the mechanism.

regas with hychill. it'll likely get uncomfortably cold in the middle of summer

Lel everything will be your problem on that piece of shit

>>28911666
American cars come with the best ac, my cars ac goes down to 15c and I never have to go that low, 18c is cold enough on a 40c day

>>28910798
Uhhhh no it doesnt.

Turning the AC off in a shitbox was the original sport mode button
I fondly recall doing this to pass people quicker in a Toyota Matrix

>>28912424

kek

This isn't that cold. On a 40C day, you should approach freezing on the highway fully cranked and in re-circulation mode.

I only charge my AC on a 40C day to ensure this.

Chinky vaccum pump, AC lines and gauges and a bottle of HyChill will set you back $400AUD. Good for 20 charges. R134a is dogshit compared to HyChill.

Burger AC was some of the best in the world. Was

If you ever wondered what kind of poverty spec shitboxes and garbage ass vehicles the average 3rd world /o/ enjoyer drives then this is the thread for you.
"muh mileage"
"i turn AC off and its like sport mode!"
"i use MY AC for engine braking"
"AC kill your power"
"AC doesnt really keep you cool in the sun"
>holy fuckin shit these people
>t. 1st world AC enjoyer

From Florida, yes the sun just beats right on through the windshield and windows. Have to use the "illegal" shade of tint to mitigate raw sunlight.

>>28912906
Some people like cars from the last century.
In the '00s car AC systems switched to electronically controlled variable displacement compressors instead of acting like an on/off switch that drew the full level of load from the engine any time the compressor kicked in so you'd notice the added load more easily on older AC systems.
The more you know.

>>28910856
Rolling your windows down is basically going to be just as taxing on efficiency. So might as well use AC.

Looks like my butt dyno is properly calibrated, because my 2004 piece of shit really doesn't lose much speed with the A/C clicks on at minimum fan, but when it's max fan speed and you're accelerating, you get a crazy torque dip, it practically stops accelerating like you hit reverse vtec.

>>28913403
>2004
pretty sure most manufacturers had figured out how to disengage the clutch during heavy engine loads by that time

>>28910851
in my bigass chevy van with one working window, I crawl uphill doing 40mph and I do it in chilled comfort

>>28913431
My car didn't get the memo because it's the slowest fucking thing ever when I'm blasting to cool persnickety passengers on a hot day, A/C works comfortable though but the car efficiently only goes 45 mph, it's insane.
