We typically advise used car buyers to change it if they get worse than 28mpg on the freeway (long flat freeway trips) or if it'* over 50k old, or if they don't know if it'* original.
I gather that is 28 mp U.*. gallon? Mine is getting about 25 to the Imperial gallon when I drive it and 20 when the wife drives it. She'* taking it from Vancouver Island to Salt Lake City next week, I'll get her to keep track of her gas on the trip and I'll do some calculating when she gets home.

25 imp. mpg = 20.8 US mpg
20 imp. mpg = 16.7 US mpg


Might be due time for a change if that'* highway
