Who owns a 6-cylinder, Wrangler-type (CJ, etc.) that knows what their real gas mileage is ? I know, I know ... there's all kinds of driving. But this will be a daily driver in an urban area, with occasional trips, and some off-road. I figure if you can do the actual math, then you can describe the kind of driving that got you there. Anyone ??? BTW...how about Tacoma 4WDs also ?    Stay safe

Any lift, agressive tires, gear change?  Those change the mpg a bit.   My TJ when I had it got 12mpg, but it was lifted 6 inches with large tires and a gear change.   I think the sticker tag said 16 so it should be around that.

My 1990 Cherokee gets about 12MPG city, and maybe 13/14 on highway when driven gently. Granted, I do need to replace the thermostat and O2 sensor.


Edit to ad: No lift, auto tranny, tires are the biggest that will fit without any extreme rubbing.

I have an 88 Jeep Wrangler with a 4.2L 6 cylinder engine and 5 speed manual transmission. It has 150K miles and I still manage to get 14 mpg on the highway. I'm having to use 93 octane and could use a rebuild, but she's got plenty of life left in her!

Ditto on my 91 Cherokee Sport, but I get 17 mpg regularly. I've got over 185k miles on her. If I hit a bump, there is rubbing, so I have to get a lift soon.

Edited to add:
4.0 I6, 4WD, Stock everything. But it's not a Wrangler, so I'm not helping, huh?

I had a 95 Wrangler with a 2.5 and I got about 13/15, and had an 86 Cherokee with the same motor and about the same mileage.

Hey guys, we bought another YJ. This one has a body, the other one is just a frame. Put the two together...add a V8, 700-R4, Currie 9 inches, soa conversion, 37 inch tires...

We're gonna try to have it together in time for the Easter jeep Safari in Moab.

We have a TJ too, no data on mileage, sorry.

ThankYou, one and all. Even in the "flatlands" of South Florida, it would seem to be a big bullet (mileage-wise) to bite. Presently, I'm getting 29-30 in my '92 Miata. Hey, when the teenager was a baby, he didn't have buddies at batting practice that needed to carpool. So it's time to move to something with that capability.
Thanks again, Merry Christmas, Happy Holidays,
Pray for Peace and keep one eye baddies. Stay Safe

Not a Jeep, but…

My stock, 2003 Xterra, SE, 6 cylinder, 4X4 averages to 17.993 mpg all things considered.  Moderate driving on the highway yields about 18.5, 18 in town.  What pulled the mileage down was a snowstorm when I was in 4 high, 15.2.

Yes I am an ubergeek that set up a spreadsheet for my gas expenses.

An average of 1826 miles per month; I spend an average of $230.  This is with 91 to 93 octane fuel at Mobile and Sunoco in New England.

YMMV, literally.

IM me for more info.
