Ok i did a little reading and found that at idle you use about a gallon per hour of idling, so shutting down the motor will save you a gallon for every hour you are idling. IMHO it just isnt worth it to shut down at every stoplight i get to, have you ever timed how long lights usually are? I know at the one bad light I have to go thru to get to work is right at 1 minute in the end how much do you plan on saving by shutting down at a light, you can do it if you want but im gonna be running at the light listening to the sweet purr of my 5.7 liter.
