I don't consider in gear to be coasting at all. That's engine braking.

Coasting is in neutral, either EOC or engine on. EOC gives you infinite mpg, engine-on gives you high (100-300) mpg.

If you have to stop due to a red light, stop sign, or traffic backup, use engine braking where it cuts off the fuel flow. Any other time, go to neutral. The longer coasting distance easily overcomes the slight bit of idle-level fuel consumption.

The fuel consumption while the engine is off is related to a specific revision of scangauge. 3.15, I believe. Mine is an earlier one that reads an accurate 9999mpg in the same case, but it doesn't know about DFCO.
