My fuel economy went up 10% by changing the time I leave for work in the morning. By leaving at 5:30 AM vs 6:30, I reduce the traffic I encounter by about 75% and, even in city driving, I can use the cruise control half the time. Speed limit is 45 and I set the cruise at 50. My mileage went from around 24 to almost 28. I still get stuck in traffic going home though.
