My car is a bone stock original 73 Duster with a 318 2bbl, 904 tranny and a single trac 2.76 geared rear end. I drive to HIGH SCHOOL and around town every weekday and cruise it almost every weekend. I have the a/c on most of the time(good ole Texas climate) and my foot ocasionally gets "numb" at a stoplight or intersection. It, on average gets around 17 to 18mpg every week, and around 20 on the highway (2.76 gears). I can fill my 16 gallon fuel tank up for about $45 dollars. I usually can go without refueling for 10 to 12 days. It is my only car, if I leave the house I am in my Duster. I would drive nothing but a mopar muscle car since before I could drive, I didn't care about mpgs I just wanted an old mopar like dad, I just got lucky with this A body "economy car".
