2001 Sport, aw4, dead stock, tires included and no lift, with roughly 42,000 miles, last tank was 23.5 mpg (US converted as I am Canadian and know about our larger Imperial gallons). Now the mileage mix was 80% highway at about 60 mph on cruise control but half of that was pulling a God awful 5X9 U-haul trailer with a giant double pig roast on it.
I wouldn’t say that I drive like an old guy even if each day I am becoming one but I don’t find the Cherokee to lend itself to going 90 and being flung through the corners or slid around them. I am happy sitting just under what our police officers will allow on cruise, this works out being a very efficient, if anything on a Jeep can be called efficient, speed.
I use full synthetic oil, check my tire pressure and air filter, stock, regularly checked.

1989 Cherokee base
4.0 with bosch injectors
Goodyear Wrangler Authority 31x10.50r15
Stock gears with almost 200000 miles on the Jeep
13-16 Mixed driving city/highway/offroad
I got 19.4mpg this week (mixed driving and none offraod) and that with a heavy foot at times lol. Im quite impressed to say the least. When I put the new injectors in I got 13-15mpg but now its crazy how much Im getting. Granted this is a rough estemate from the miles I have driven and the amount of gas I have used from where the fuel gage is sitting at so not the most accurate but probly not that far off either.

I just dont like people spewing false information, especially about hypermilling cause i live in the land of the hippies and i have to deal with dummys all the time. It makes me want to buy a huge diesel and drive around town revving and blowing black smoke.
The next time someone says they are being green by driving a prius, laugh in their face. Ask them where does the heavy metals come from, where are the batteries made, and where do the batteries end up? answer: canada, japan, landfill

mpg, and how...?
I have a 1991 cherokee. It has 334xxx miles and 30x9.50 BFG'S. I rebuilt the motor complete about 30k back. Had it bored 30 over. Everything else is stock. I did add an AIR RAID throttle body spacer, and I run a bottle of basic berrymans and a bottle of gumout octane booster every fill up. Currently getting 22-25 mpg each week. Much depends on traffic. My highest was 27 and low was 20. my average runs 22.5. Tranny is a stock ax-5 standard. At every oil change I add 1 quart of lucas oil stabilizer and 1/2 quart duralube. The oil filter is over sized which gives better oil cleaning and more oil to the engine. Total oil capacity is 6.5 quarts. Thats what I have and do. Good wheeling!

2 company vehiclee--both exactly the same specification--BONE stock, 4.0 liter 6 cyl auto Command Trac. nearly 100% street driven same fuel choices, same commute--60 miles a day about 55 miles at 60/70 mph and the balance city driving.
1) 1999 14.5 mpg
2) 2001 18.0 mpg
That's a 25% improvement.
I see the 2001 has no distributor, but what other changes account for the huge difference?

I suppose you're going to mention that it's a 4 cylinder now.
