It's not.

Coasting is the main thing that got my mileage up since joining ecomodder.
Reducing weight etc will have helped, but coasting really was the major change. I was using DFCO a lot before, and quite good at it I can say, downshifting and all that.

The problem with DFCO is that you effectively brake using the engine.
That means you're not getting anywhere near as far with DFCO as with coasting - even when it's engine-on.

It's simply amazing how far your car will coast.
I try to coast up to every necessary speed reduction, and have to start from rather far out.
