Unhappy 2004 Jeep Grand Cherokee -fuel mileage out the window!

Hi everyone, I am having an issue with my Jeep 4.7L. I am only getting 87km to half a tank of gas. There are NO leaks, changed everything from fuel filter, plugs, new battery, checked injectors, idling pressure and still the mechanic cant find anything wrong.....anyone have any ideas?
thanks

Welcome to CF.

You'd probably get more info on this forum:

I know the one time my mpg dropped way off it was due to bad O2 sensors.
