I have a Tucson, 2005, automatic, 4WD, 6 cyl. Though I got a good deal when
I stumbled on a used one (3300 miles) and bought it at a good price. But
mileage has been awful. I've put 2000 miles on it so far, and mpg has
dropped off from 13 mpg to current 10 mpg... I had only one lengthy freeway
run, about 200 miles, and even then only did about 17 mpg.

Does anyone have any thoughts? I took it to dealer; mechanic says there is
nothing wrong with car, but I disagree. I don't know how to approach this
problem mechanically.
