Stop and go city traffic is ugly. Put a ScanGuage11 on and see what's happening.

Those 3 to 5 mile trips get you 17 to 19mpg, maybe 20 if you time the lights. Short little trips just kill the fuel economy. Could see no difference running the a/c or not using the ScanGuage.

The nice freeway drive at 70mph for 20 some miles will crank out 30 to 31mpg.
