I bought my 2011 Patriot on December 20, 2010, in large part because of the advertised gas mileage. The window sticker for my 2.4L, CVTII, 4WD is 21 mpg city and 26 mpg highway. Thus far, while driving in very light city conditions and then on a highway trip to Pittsburgh (from Erie, PA), I have been getting 17-18 mpg and 21-22 mpg, respectively. That is far below the advertised mileage, and that's with only a couple miles of 4WD driving time, and I do not let the vehicle sit idling at ATMs nor do I let it idle a long to warm up (kept in a partially heated garage). On my last vehicle (2007 Cobalt) I routinely beat the sticker mpg by 5-7 mpg, so my driving habits are not at fault.
