read this.....again
it's easy to get fixated on something like this....had a tarsus that did the same thing.
But there are probably three other things you could do to get better mileage.half of a quarter of a gallon OVER 1 hour is nothing.
maybe you can reduce the rpm in half, but it doesn't use twice as much gas to run 1500rpm (IN NEUTRAL). And honestly, how much time do you really spend coasting....

you can discuss all the 'theories' you want until you are blue in the face.

everything in life is a bell curve. It's not worth dealing w the fringe stuff UNTIL you address the stuff in the middle.
SO....... how much time and distance is spent 'coasting'? (the fringe stuff) Which by the way has the LOWEST consumption of fuel on the whole trip probably only 10-15% of driving consumption.
FOCUS on the stuff that matters.
