4 Inch Rusty's Lift
BFG All Terrain (33x12.5R15)

Uhhh... I get about 12 mpg city and 18 highway. FML

 

wouldnt we have to change the speed sensor because of our taller tire hieght? not an accurate way to read the odometer...

when i go 70 im actually in the 80's i think.

 

97 xj sport, 7" lift,35 tires,456 gears,8 to 12 mpg

 

93 Sport, 2wd 4.0 Auto 4.5 lift 31 bfg mt, 18mpg average have gotten 23mpg one tank cause i wanted to see what could get if i babied it. good to know when money is tight

 

Ya know I think my mileage went up when I replaced the cracked output housing and filled my transfer case......

 

19 on eaxh of the first 4 tanks through it.

87 4.0 30"tires

 

All Stock 4wd 4.0 Aw4 3.55 gears, with 30" BFG AT's.
Driving to work and back, a half and half mix of city and backroads driving, I get around 18-19 if I drive her easy.
On a round trip all-highway drive from Denver to Cheyenne, I verified the distance with my GPS. Doing most of the trip between 70-80 mph, I got 21mpg.
On a day spent wheeling up trails like RedCone, and Radical Hill, with the trip there and back from East Denver, I still got 15mpg.

For comparison......
My Wife's 2006 Hyundai Santa-Fe 2wd 2.7 V6 AT gets avg 20mpg around town, and between 22-25 on the highway.

My '90 Yamaha FJ1200 gets about 40 around town, and 43-45 on a nice long backroads ride.

My 1995 Firehawk 330hp LT-1 5.7 6-speed MT 3.90 gears gets 19-20mpg around town if I baby it, and 26-27mpg on an all-highway trip if I keep it around 70mph.

Now I just need to decide if I want to freshen up my spare LT-1 I have sitting in the garage for the Jeep.........

 

89 xj 4.0 sitting on 38s with 410 5 speed 12/15 avg

 

I drive my jeep easy and I can get at best 18/19mpg. It's an 88 Pioneer on 33x10.50s with a 4.5" lift and a roof rack. Dispite what people say the rack didn't change the mileage. If I drive it harder I will get 12-14mpg on avergae. I'm just happy to get double digits. Our last truck was a 76 Chevy 454 long bed quad cab 4"lift on 35s. I was happy to get 8mpg haha

 

90 cherokee sport two door, 4.0, 5 speed, 3.07 gears, 235/70/15 goodyear wranglers. I get 15 to 18 in town and 20 to a best ever of 26 on the HWY. My jeep has 421,000 miles on it as of two weeks ago. I drive about three times a year 1800 miles one way between Missouri and California. this mileage is rock solid even with the AC running. My mileage does drop once I get a couple of tanks in Cali though, something about that smog gas.

2000 cherokee limited with stock tires and i get 22-24 mpg running 65 and on average with highway and town driving 19-20 mpg. Everything is stock except i did do the injector upgrade.

 

Why do you need an accurate fuel gauge to calculate MPG? All you need t do is to fill up, record your odometer reading, drive the tank out, fill up again and read your odometer again. Take the mileage and divide it by the number of gallons. You can do this without a fuel gauge.
