I've been curious to find out what other Jeeper's have been getting in their XJ's.

I get around 10 MPG

 

15-16 mpg

 

There is alot of threads just like this, but i get around around 12 mixed. 33's and 3.55 gears

 

16.8 with my 95 ZJ 4.0 in mixed highway and city driving. The best I've ever averaged on the highway was 21.3mpg.

 

Stock xj average 22-23. Last tank filled up at 394

 

I get about 8 , no joke.

 

you guys getting low mileage have something seriously wrong or your sitting as high as a semi...

I have a stock '97 without cat and today checked it (manually from same pump I filled up at) combination driving I'm getting 19.3mpg...

now this was a test and I've been really light footed and doing the speed limit.. and keeping it around 2k rpms...

Haven't had the jeep long but I'm a stickler when it comes to mileage, I'm very curious what I can push out of it all highway miles...

my Duramax get around 20 on the hwy....

 

Not entirely true. It's really easy to get a little under 10 if you are on big tires, stock gears, heavy bumpers, and roof racks with a moderate - heavy foot. It's not all that uncommon.

Another thing to take into consideration: if you are on bigger tires, your speedo is reading UNDER what it really is, unless you changed your speedo gear along with the bigger tires, which I assume close to nobody has done. So you're actually getting slightly better mileage than you think. I do mean slightly though.

That said, I'm sitting on 33s with stock gears and get about 12 MPGs. Basically all city driving though.

 

12 on average

 

~18.5 on pavement
~15 off

235/75's btw..

 

14 31s and 355 gears

About 14 on 33's

 

14-15 mixed w/3.55s on 31s...with the correct speedo gear to make everything accurate.

When I wheel, it's usually 12.

 

I average 19 in my 87 xj on 235/75 mud tires with 237,xxx miles. 2.5, 5 speed, 4x4. Not bad imo.

 

About 15 sitting on 31's...all city (if you want to call it that) mainly rock and dirt roads. no highways around that I can drive to
