Gas Mileage Issues

Just came back from a 3,500 mile trip.
The gas mileage and trip odometer says I got 25.3 mpg (almost all freeway driving).

At times it would say after resetting the fuel computer. it would say up to 27 mpg while enroute.
In town after I filled at home it would say I could go around 270 miles or so.
However, on the trip it started changing after all fill ups in the 400 to 450 mile and one time 500 miles to empty after fill up.
But,The last fill up was 6.789 Gal. and only went 95 miles all freeway?
That is less than 14 MPG!
Regardless of what the computer says if I put in almost 7 gal after filling (and it was full) up only going 95 miles that's an issue.
I live in a small town very short trips and idling more in the summer but I'm only getting about 15 npg in the city, ouch! The 9 speeds don't do much in the city.

You said it was, but any chance the prior fill-up wasn't actually completely full?
