Excellent thread. Great to see cherokee's averaging mid 20's. That's what I'm shooting for. Just got a 96 cherokee I6 auto. Careful driving was netting about 20 mpg. Got new tires last week, 205x75x15 with studs (suppose to have been an option on the cherokee at some point), and averaged right at 1.5 mpg more on trip across state this weekend. Best tank of five yielded 23.8.
Was pretty excited about the aero mods, but on one leg of the trip we bucked 20 + mph headwinds for 187 miles at 60-65 mph (usually keep it under 60) and milage only dropped to 19.8. I know it's not that simple, but if fighting strong headwinds and going faster drops FE less than 2mpg, maybe there are mods that would be more productive.
Am going to modify the air intake next and see if that makes a difference.
