only 160 miles? god damn lol i got a 2 door x and get atleast 240-250 before the fuel light comes on. I fill up between a quarter and E mark

 

That's probably with 3.21 gearing, 28" street tires on flat ground. I dont really drive fast but I dont baby it starting out at lights either. I think it's the 35's and hills that kill me!

 

actually half of it is highway milage . has the 4:10 gears, but your right on the tires (for now). I too got a heavy foot, cant help it sometimes lol.

 

I only get 10 mpg. We calculate it at the pump each time we fill up so it's as accurate as the odo (which is, granted, an unknown). This is almost all city driving.

We have 5.13's, 35's, and the auto. Sounds like others with similar configs are getting far better mileage than we are, and we try to drive carefully. Rubidonn, are you auto or manual?

 

Dear God! Only 160 miles per tank? YIKES. Not counting when the Jeep was still brand-new, I consistently get over 16 MPG unless I do a lot of offroading on the tankful, and average between 17 and 18!

 

Yikes is what we say every day at the pump. A half hour round trip drive to my dad's house takes half a tank. WTF????????????

 

That is when the light comes on. I still have 3.5 -4.0 gallons left in the tank. I am sure when my odometer says 160 I have really driven 175 or so due to the bigger tires.

 

With a mix of city and highway, I typically get 200-225 on a full tank w/ 4.10 gears, stock tires, and suspension. If I were driving straight through on the highway, I'm sure I would easily get 350. The JK gets better gas mileage than my 97 Cherokee with the 4.0L. I took that on a road trip from PA to Florida this past March and we eeked out just over 300mi on a full tank doing 75. I bet I could push the JK to almost 375mi if I wasn't driving like an idiot. I think fuel economy has a lot to do with driving style. If I drive like a jackass my eco tanks, and I typically need to fill up around 180mi if I'm just tooling around town.

 

I recently checked my speedometer and my odometer against a gps and my JK with 35's is roughy off by 10%. Anyone else do a check?

 

23 miles per gallon here! expect it to improve a bit more once this oil burner is run in a bit more
