Have you confirmed this with like, a scangauge or a mpguino or something? If not, what are you going off of?
Most people get low mileage @ low speeds because they can't keep their pedal still, they keep either letting the speed go to low and it downshifts and they put the pedal down to get back up to speed, or they're foot gets on the gas too much, and they creep up to a higher speed, slow back down, creep back up, start falling a sleep at the wheel, and mpg suffers.
I don't know about you, but my Jeep traveling down the road @ 1250-1300 RPM @ 45 gets much better mpg than it doing 2000 RPM @ 70. or 1550 @ 55, or 1700 @ 60. Thats how its been in all the cars I've driven.
Rant over.

The Dodge has a 4-spd manual OD transmission.All tests were conducted in high-gear,at constant speed,on Interstate-35,with round-trip runs made between Sanger,TX and Ardmore,Oklahoma(270-miles).Runs were conducted back-to-back,with immediate delta-velocity runs,with velocity as only controllable variable.
