I am getting around 17.8 all around driving according to the on board computer. 09 auto Rubicon unlimited. Long distance on the highway the average creeps up into the mid 18.5 range.

 

I get about 17 mpg with mixed hwy and city on an unlimited rubi with 6 speed. That is a lot better than my TJ ever got.

 

In town I normally get 17 - 18.

On the freeway, with cruise on, I can tap 21 easy, sometimes 22.

All hand calculated, not computer.

With a big wind behind me, I can get 25....LOLOLOL.

 

13 city 17 highway on a long trip.

Sometimes 9.

Its an awesome site. Lets me keep track of everything, along with the history of my jeep since I got it.

 

By the computer I get 18-19 mixed driving. If I reset going to work (25mi) I will get 22-23 @ 55mph backroads. Take the highway and it drops to 17-18.

 

I have been driving smarter. I didn't buy a jeep for good mpg that's a pipe dream in a jeep. I have a 6 speed 4door and I do the speed limit. I'm getting close to 400 out of a tank. I use the cruse control in the slow lane but most of my driving is highway.

 

'08 Rubi, auto, 800 miles on odo and I'm getting around 16 around town. As far as highway milege well can this thing go that fast......

 

Our 4 door Rubi gets about 17 mpg in town and 22 to 24 highway.

 

Oh.......I forgot to mention it is a 2008, with just over 20,000 miles, automatic, 2008, carries a Warn front bumper, grill guard and Power Plant as extra weight.
