how about this...
In my '93 Caddy, I have a real time gas gauge (injector pulses / wheel revolutions)
-if i coast in gear, I don't have fuel cut off, so while the engine might be braking, it is still using some fuel at the in gear lower rpm, and comes down through the gears at lower rpm
-if i cost in neutral, the rpms jump up [probably so there is torque when dropped back into gear ] so i'm still burning fuel in neutral, possibly more and it is not going to the wheels
-note: if i EOC by turning the key, i'll often get a smell of gas upon startup. and with the computer not liking the power off, nor any injector pulses, mileage is tough to compare
The instant gas gauge reports similar fuel usage and sometime more usage in neutral, but the gauge doesn't let me measure averages for a couples minutes of coasting very easily
