Huh that's weird, my 2.3 lima is the opposite it gets 23 around town and 23 on the highway lol. What rear end gear does yours have? Mines a 4.10.Dont forget you need the wiring and ecu. Some parts of the harness will swap over but alot will need to be changed. And the ecu's are obviously not interchangeable. You'll also need to do AC lines, coolant lines, exhaust etc. Cost and work wise you're going to be in as deep as a 5.0 swap (plus the trans work).
And for what its worth my duratec gets good highway mileage 25+ but city driving it barely gets 15...
