RE: Neutral vs In-Gear

OK, I did some careful observation of the GPH (gallons per hour) on my ScanGauge II this morning during the commute. As far as the civic is concerned, this is the data I've got:

DOWNHILL COASTING:

In-Gear : 0.00GPH, but with slight engine braking
Neutral : 0.22GPH, with better speed retention

COMPLETELY STOPPED:

In-Gear : 0.20GPH
Neutral : 0.22GPH

So I'm happy enough knowing that I'm only using .02GPH more by keeping it in gear while waiting at a light vs Neutral... however I'm still on the fence about which is better for downhill coasting... for the sake of transmission wear, I'd be inclined to coast in-gear for most of the time.
