Fuel Economy With A/c Auto Mode

[Isuru Udana]

Hi all,

I have a nissan sunny FB 15 super saloon.

In super saloon climate control A/C (Auto mode) is a feature.

Is it economical to use this mode rather than use 1, 2 modes?

Is there a impact on the fuel efficency with these A/C modes? or fuel efficency does not depends on what ever the mode we use?

Thanks

In theory it would be more efficient. In the real world the savings are negligible.
