I've done EOC with every vehicle I have owned with a manual transmission over the past 5 years.
I honestly think it does help quite a bit actually. Its not just about rolling up to a traffic light and leaving the engine off.
Rolling down hill can save you a lot. In spokane on division st there is a hill going back towards down town that is pretty steep. I held my speed at 30 and put it in neutral and shut it off as soon as I crested the hill. I was able to roll over a mile before having to stop for a traffic light. If the light had been green I probably would have been able to make it to the up hill stretch about 1/4 mile before the river bridge.
If it is a short down hill drop that is only about 50-100 ft before flattening out or going back up I will at least put it in neutral and use the momentum to keep me going. If the light turns yellow and I am close enough that I feel it is safe I give it a little bit more gas to get through the light...figure that short slight burst is more efficent than having to start from a stop again.
All those 2 block EOC's approaching a light, and 1 mile + stretches starting at the top of a hill all add up.
I find that I drive differently if I have no intention of shutting off at the light (In my wifes auto tranny kia). I keep my foot down approaching the intersection and brake much closer to the other cars waiting at the light.
Every car uses different ammounts at Idle. 1/10 of a gallon may apply to your car but is your car in like new condition? Mine is in great shape but I am fairly sure that being carbeurated and nearly 30 years old it uses a bit more at idle than it did brand new.
I am experimenting with my car to see how much of a difference there is between normal people driving and hypermiling.
Last tank I averaged 28mpg all city with 1 10 mile hwy trip.
Interested to see how much of a change I get on this current tank. I've already gone 50+ miles and the guage has not moved at all.
I found that there are roads that connect all sides of spokane so I can go anywhere I need to without even touching the hwy.
