My 2000 Mitsubishi Eclipse GT 4 speed auto is rated 18 city, 25 hwy, 20 combined.
Using Torque Pro for Android and a $12 OBD2 bluetooth module I've been able to improve my combined gas mileage to over 29 MPG. It helps seeing your gas mileage as you drive and how easy it is to improve it by adjusting the way you drive.
