Well, that's a little below the EPA estimates of 18/25, but, of
course, that's the old estimate that doesn't reflect real-world
driving like using the climate control, headlights, etc. Any codes
stored in the car? You can get that checked at Autozone for free.
Might not be a bad idea to make sure there is nothing going on that
might not be generating a CEL. I'm not sure how the computer
calculates the mileage but the old 'divide the elapsed mileage by the
number of gallons' is the best way to calculate it. My computer seems
to read a little high.

In my car I have averaged 22.78 mpg since new, 80% around-town
driving.
