I was wrong again...

A couple posts back I said I'd found and researched the drifting in neutral vs drifting in gear thing and found the latter to be more fuel efficient. Since that post in July I have been testing what i suggested. I went into hypermilling mode and tested using drifting in gear and found that it was good when engine breaking was appropriate, but annoying all the rest of the time because I kept having to hit the gas to maintain speed when normally I would not. Still I stuck with it and got 34.14 MPG after a full tank of gas. Then I switched to drifting in neutral using all the same driving techniques I had before. When I finally got through that tank, found my MPG had improved to 34.94. I'll grant you there isn't any statistical rigor here and any number of influences might have affected my results, but nearly a full MPG more says a lot to me. So I have to say that while technically the drifting in gear is more fuel efficient, in practice you may find it to either not make much difference, or even make your overall performance worse. I'm going to stick with my tried and true thank you.
