Contrary to common belief, coasting will get you lower mileage than if you left it in gear. When coasting your car does roll for longer because it doesn't have the engine friction slowing it down but the engine is using gas to stay idle. When in gear the engine friction is slowing the car down more but while doing so the engine uses no fuel at all as the speed of the car is enough the keep the engine above idle rpm.
