i just moved to a big city from a smaller city, and in the old city (seattle) i got over 40 mpg consistently, going on highways and some city. now, i drive 100% city, and there are stop signs at every block, the traffic lights are not in sync, etc. i have been averaging less than 30 mpg, and sold off my supermid because i dont want to look at that while driving in the city, can be dangerous.
so is there any good techniques that i can use? right now i try to keep the car in motion and not to a full stop on every stoplight, not make a full stop on stop signs (people do that here). I fill up once per month, sometimes even longer. everything is city driving where i live now. i never fo past 2000 rpm, and are always in gears 1-3, since i dont need to go over 30 mph here.
