After reading the numerous low mpg posts I’ve decided to post about my average fuel economy. So far the Renegade has been averaging a solid 25 mpg (calculated) compared to the onscreen average of 24.2. I’ve been logging all my fill ups on Fuelly so that way future perspective buyers can see what to expect. Low mpg was 21.3 with a high of 30. I have a 2.4, 4x4.
