Lately I have hit more stop & go traffic here in DC and have found my commuting mileage dropping from the mid-to-high 50's to the mid-to-high 40's. I know there's only so much you can do to keep mileage up in stop & go, but I was wondering if it is better to keep the car in lower gear for longer in these situations (feathering it to maintain speed) rather than shifting to 3rd as quickly as possible and then flooring the pedal to have the assist kick in. The car responds much better in the first situation, but I'm trying to get the best mileage. Generally speaking, how high should the rpm's be when driving around in city conditions - 1k-2k, or 2k-3k?
