love my 89 Jeep Cherokee 6cyl auto 4wd (130,000)... a real workhorse, takes lots of abuse, never lets me down...
EXCEPT the gas mileage which had avgd 15-18mpg (not terrific in the 1st place, but consistant) has dwindled over the past year to about 13mpg, no matter how carefully i drive. of course this results in much pain at the pumps. environmentally embarrassing also!

Please list the various things that could be the cause of my jeeps lost fuel economy-- thanx

You haven't said what you have tried to cure this ill...is the jeep fuel injected or carburated?
