Engine Braking and Fuel Economy

[RandallNeighbour]

So someone please show me that engine braking does not use any more fuel than putting the car in neutral and applying the brakes.

I tried to find something definitive on the web, but I only found debates both ways on it.

Can anyone point me to some empirical data on it (vs. a simple opinion based on one's current logic)?

My thinking is that if one is not depressing the gas pedal and the car's inertia is causing the high RPM's, the fuel tank is not being drained by engine braking. But if hard evidence proves me wrong, I'm happy to change my position.
