The fact is that running the Air Conditioner (A/C) really does increase fuel consumption, this is because most vehicle air conditioners require engine power to operate. ... While on the highway, open windows increase the car's aerodynamic drag, and that makes the engine work harder which in turn increase fuel consumption.

while some people feel turning on your car A/C double the fuel consumption rate which it does not.Having your air conditioning turned on can increase fuel consumption by up to 10%. ... Once your car is cool, it takes less energy to keep it cool, so using your air-con on a long journey won't be as harmful to your fuel consumption as it is for short trips.

I'm trying to understand ur grammar and point becos u kept contradicting urself

go through it again....

No. AC doesn't increase fuel consumption.

alphaNomega:
No. AC doesn't increase fuel consumption.

what's your point.....

Load on car engine increases fuel consumption

Carrying 4 overweight ladies in ur car will increase fuel consumption funny but true

Ac is an additional load n will increase fuel consumption most esp on city but difference may be negligible on highway

Nope....it doesn't

Definitely, it does. Common sense na. More load on engine increases fuel consumption. I have not been using my AC now cos its faulty, I noticed the fuel decrease.

It does increase fuel consumption. Unless you are ignorant.

@OP, are you asking for our opinion or you have just made your conclusion?

I'm open for learning, if you think it's does not bring in your ideas let reason together...

God help u,your catalyst has not been removed. U go burn 15 litres under 1hr

If you have a VERY SOUND engine, you won't notice the difference.

let it drink the fuel, why should I surfer in dis heat because I wanna save 10% on fuel costs. U see some1 just dey sweat like pig inside nice car, so it's all because u dey save gas

Horlacares:
Nope....it doesn't

it does and its proven

Why should it,well it all boils down to like 3 factors. Are your injectors working properly,are you buying unleaded fuel and also what is your gs mileage. If its a corrolla and you are getting poor gas mileage even with the AC on,forget catalyst,just park the corrolla, and relax. U had been scammed

The answer is Yes and No.

Yes when you speed is below the range of 65mph to 70mph, Above that, your vehicle experiences drag which increases fuel consumption. At this point, windup and use your AC

Exactly what Op says, for city driving with sower speed, it consumes more fuel. For highway with higher speed, the car drags befause of air when windscreen is down and hence more fuel, so it safes more fuel to use AC on highway and wind up.


I'm actually just learning this that AC on highway safes more fuel than no AC on highway with windscreen down.

Yes, it actually does. You'll notice that whenever you switched off your ac, you'll felt some vibration. That tells you that the has more loads
