Probably a little. You save about 0.00004 gallons for each second you do it. But you incur a fair amount of engine braking. And any fuel that did go through the engine if DFCO were not active would go to propelling the car forward.

So it really depends. Judiciously applied, it can help. But the ECU software is designed to do best when you don't try to second guess it.
