Hey I was thinking of taking my JK for it's first long trip.

I have 3.21 Gearing and the tires that come with the Rubicon's with no lift two door, what type of mileage should I be getting if I'm gonna cruise at 75 mph?

The farthest places I've gone with my JK was Sedona but I don't remember how good of mileage I got on the highway.
My work is only 5 miles from the house so I never take it on the freeway. So I only have been able to calculate city mpg.

I'm probably gonna be in the slow lane most of the time to give you an understanding of what style of driving I will do.

I can usually get 240 miles a tank on city driving like its a race car.

 

With my 2dr auto, I was getting between 18-21 mpgs when I was stock. But our speed limit is still 55 around here, so I drive about 60 all the time.

 

4 door and the spec's are in my sig. I have gotten as much as 22 mpg on cruise @ 70, hand calculated.
