I always hear ppl say on AC will increase the FC. However when we off the AC and wind the window down, the air rushing in will increase the drag, hence increasing the burden on the engine, thereby increasing FC also....
so which is which? to save fuel, do we on AC or wind window down?

window up AC off...that way u can reduce drag and save the FC on no aircon, end result is that u might sweat like nobody business

if i didn't remember wrongly. at low speed, its better to wind down windows.
