I average about 22 mpg with my '01 GT, and 18 mpg with my '66 i6. (I always drive the '66 "enthusiastically" ) I drive most of the time in the city and about a 1/4 on the highways..
Since you don't drive fast... maybe you should get your engine checked out... like a full tune up.
Are your tires bald? Do you drive in the city all of the time? Is your emergency brake on? There are way too many variables for us to figure out the problem, unless you become more specific.
Hope you figure it out
