beaters what options do us mopar lovers have?

I am guessing by your sig. that your dart has a 225?

If so you need to learn to tune it.I constantly got in the 20's with my 70 dart 4 door,and it has a/c(that worked and I used)and power steering. If you need better than 20's for mpg,get a K car or neon as stated above.The neon and PT saved chrysler,it was not a turn for the worse,it was a much needed change to stay alive in a mpg market.
