Turn off the aircond will gives extra mileage?

[carlover1234]

Does it true that if we turned off the aircond, it will gives extra mileage about 10km?

 

[ixeo]

No.
Especially not if you open the windows.

I can guarantee you, you turn off the air con, mileage will be worst, cause i will drive faster, so can arrive faster, and get out of the sauna of a car without air cond.

 

[lsm1991]

extra milage, probably.... (assuming everything else is a constant and u dont wind ur windows down)

will it give you an extra 10km? who knows.... 10km is arbitrary

 

[6UE5t]

Theoretically it should give you some extra mileage provided all else the same but does that extra mileage worth it to be in a sauna while driving?

 

[vr2turbo]

I only off air con when I need slightly more oomph......hhahahhahahhaha

On a small engine?
Yes, we can see the improvement..not significant but more noticeable.

On a big engine?
Nope. I know in theory there is improvement as engine worked less but in reality i dont see significant improvement.

At least that is what i experienced. Anyway, in this recent weather i will gladly pays more for fuel when driving with aircond ON.

I've actually tested this before. On a myvi 1.3 maintaining 80-100kmh speed maximum the fuel consumption is considerably better. About 2-3km/L more fuel economy if aircon is completely off. With engine on I lose that 2-3km/L easily with the same speed and distance travelled. The thought process is whether that savings and mileage travelled worth the heat and endless suffering without the aircon.

Having said that though the Myvi aircon system is not well known to be efficient or reliable so potentially the aircon itself is a problem.

On the Innova I tried it on there was a difference when I travelled highway with max 110kmh. City driving just made my passengers hate me.

In stop and go traffic yes you gain mileage. on the highway at highway speeds no gain.

 

[vr2turbo]

Yup, highway speed with windows down a lot of drag.......lol

FC is one thing.
I also learnt another vital info this week. The weather is soo hot these few weeks that i decided to drive to work instead of riding. It was so hot to ride that i thought its no harm to spend more on fuel so i can stay comfortable with aircond blowing in my car.

My theory is super duper wrong. It was all good in the morning. During lunch, i was sweating while waiting for the cabin to cool down and same goes when i go back in the evening. I never sweat when riding despite the heat. Its very hot but never sweating.

Your aircon not strong enough bro. I go out lunch every day, never sweating in the car.

You got basement parking?.......lol

I don’t know about him. I got remote climate control. Can cool the car via app.

so park under hot sun, moment I get in the car it’s cool.

I heard theories if you off your air cond your engine overheats faster. Part of aircond is to cool engine?

 

[6UE5t]

Yes in the office, but from lunch place 99% of the time is outside.

Aircon got extra fan dedicated for itself, so it should not affect the engine temp if the engine is healthy.

Possible,in worst case scenario of a failed radiator fan....that is...if the engine is running 2 fan of which one for the aircond and one more for the radiator. Remember that the aircond condenser is in front of the radiator and whenever any of the fan runs, it sucks air through both the aircond condenser and radiator. If the radiator fan fails, switching ON the aircond can delay the engine overheating.

Part of the aircond is to cool the engine?
Nope, its just that the aircond and radiator share the same area for airflow and sometimes fan.

My parking is super duper open and with current weather...ouch.

Riding is better. Riders dont even sweat despite wearing jacket under the sun.
