I would think that shutting off the engine and restarting would not use more fuel.
The only time it uses more fuel is if the engine cools completely and goes into a cold start mode (enrichen the mixture).
I watch the ScanGauge on my wife's Acura TL just go down, down, down while idling at a long traffic signal.
Very discouraging after working hard to build up the trip MPG. I shut it off at traffic signals that are known offenders, but at short stops I leave it running. I don't want to wear out the starter!
Her car will average 26-28 mpg in steady moving city driving, it's the stops, idling, and getting back up to speed that kills the mileage, then it's averaging 23-24 mpg at best.
