poor gas mileage-not O2 sensor or throttle body

I consistently get 23-25 mpg in my '95 G20 auto (102K miles).  This
seems low to me.  Most of the driving (60-70%) is on the highway.  The
car seems to run OK otherwise.

After looking for suggestions in the archives, I changed the O2 sensor
and cleaned the throttle body, which produced little or no change (if
anything, the mileage got worse).  Any other suggestions?
