DFCO uses no fuel while Neutral uses fuel, what makes more logical sense?" or something like that.
My mileage is better without dfco for my style of driving specially in hilly terrain. With dfco I bleed speed and momentum too much and my time with throttle open increases vs without it I coast a lot.
