Jason,
24 on the highway for an automatic is not that bad. MTX
SHO's can regularly get high 20's and even low 30's, but ATX
SHO's 24-27 is about the range.
If you were doing 70+ most of the time, then I would say you
are just fine. If you were in any cold weather, or
mountains then it was really good.
Total miles also depends on how much you filled it up before
taking off. I do NOT recommend that you fill much past two
or three clicks though, it can lead to the charcoal canister
(vapor recovery system) getting soaked and other problems.
Running it empty is also a bit hard on the fuel pump that
relies on fuel for cooling. (sounds a bit dangerous doesn't
it?) Another reason why Ford and most manufacturers
calibrate the fuel gauge so it reads pessimistic. Keeping
the gas tank full also helps prevent moisture accumulation
and rust in the fuel system.
