Basically, in neutral your car is idling so that all the RPMs are powered by fuel – coasting in gear, most or all of the RPMs are powered by the wheels turning, so less fuel is used. Judging what’s happening from the RPM readout, as well as from the instantaneous MPG readout, is misleading.
I was very, very surprised to learn this, since I coast in neutral all the time and congratulate myself on my efficiency. That is, I used to coast in neutral …
