I've been driving my new 2014 Jeep Grand Cherokee V6 for a little over a month now. I have about 500 miles on it (mostly New York City street miles). I have been averaging roughly 13 miles/gallon. Just wanted to see what other members here have been averaging under their scenarios. I usually disable the Eco button. Do you think my milage will improve as the engine breaks in? Thank you all in advance.

guess its best to keep it in Eco mode going forward.
If you put it in sport, and definitely with manual control over the gearbox! Try to rev to 5000 rpm on the mean and busy streets of New York City before up-shifting ! Even better fuel economy :rolleyes: than a bus...

Seriously, don't you think that the ECO button and the fact that the car defaults to ECO, happens for a reason?

ECO is specifically for gas mileage by enabling quick upshifts. You should definitely see an improvement in ECO mode. Heck, my V8 gets 16 in town (although I leave it in ECO mode unless making a quick pass on the highway).

Don't worry, that is perfectly acceptable mileage for such a heavy vehicle in a big city. I used to get similar mileage in Boston with my 2005 WK V6. When I changed to the Hemi the mileage was exactly the same. All the folks who get 16 or better in town aren't in big cities with bumper to bumper traffic for sure.

I've got a 2014 V6 Overland in Brooklyn with 6,400 miles on it. In town I average 16 MPG in eco mode, feathering the peddle. On the highway I've hit 26 MPG while in eco mode. Average for the 6,400 miles is 17.8, includes runs up to Montreal and Vermont.

Eco mode makes a big difference. Next time you drive somewhere round trip, go one way with eco mode, one way without and notice the current fuel economy. Considering how low your MPGs are, I'd assume you could lighten up on the peddle, as well...

At 1600 miles, with 75% of it being road trip at more or less 75 mph, my (3.6 V6 4x4 Limited) average before I hit the last bunch of city traffic was 25.6. For the first 400 miles it was a little over 19, which was half city/half hwy. It's really easy to suck the gas in city traffic, but I'm blown away by my highway mileage especially compared to my last WJ. And that was with my Whispbar rack.

I agree that the engine wants to go but this adds to the poor fuel usage around town. You may want to select the fuel economy display (see below) to give you an idea how your pedal relates to your fuel usage. Being gentle with the pedal gives me around 16mpg around town. I recently got 28mpg on an interstate trip. Pretty good for a 2 tonne vehicle !!!
