"Heavy traffic" is the operative term. If you drive often in heavy stop-and-go traffic you might get close to the claimed 8% improvement. For my typical use pattern I drive 12 miles on the highway, exit, then drive 2 miles through city traffic. I get two or three engine shut downs lasting 60 seconds or less on each trip. There is no way this system is decreasing my fuel use by 8%.How so? The video you linked to was one I found on Road and Track's web page talking about this very topic, and they say, "A study by the Society of Automotive Engineers found that using start-stop can see a car's fuel economy improve by over eight percent in heavy traffic."
