MPG not nearly as good as advertised--is this normal?

Hey guys, I just got an 11 Liberty. 4x4, so it's supposed to get 15 city/21 highway. After driving on the highway I refilled my tank, and have done all city driving since. I'm sitting at 3/4 of a tank after only 50 miles. I'm no math whiz, but that's 200 miles a gallon, and with an almost 20 gallon tank, if I got 15 mpgs I should be getting a little less than 300. Obviously I didn't get this car for fuel economy--would have bought a Prius if that's what I wanted! But I'm just wondering if this has been other people's experience too, because there's a big difference between around 10 mpg and the 15 they advertise!

I have the 4x2 liberty and got about 16.4 MPG. I went to when my gas light came on (1/8th of gas left) and I went about 276.8 miles. So it really depends on your driving style as well.

Don't expect EPA numbers until 10,000 HARD miles.

After that point, if you don't drive like a complete maniac, you should be able to meet and exceed those numbers.

At 2500 miles I'm at a pathetic 17mpg @ 68mph. I'm questioning my purchase. Not blaming Jeep, just myself for not paying more attention to the epa sticker. Otherwise I love the Liberty. Anthony

17 is not bad considering that you have the 4x4 version.

I bought a 2011 Limited 4 wheel drive, first 500 miles I was getting nothing much over 14 mpg. Currently have 1200 miles on it now and getting 15 to 16 mpg city. Took it on a 1 1/2 hour trip with speed average 60 mph and got 20.3 mpg windows and sunroof open, 23.3 mpg windows closed a/c running on the way back.

It gets a little better, but not much. Our last trip to Ohio to visit family we got 21mpg doing 72mph while using cruise control on a 375 mile trip one way.

We have a 2010 KK 4x4 with 12k miles on the clock currently.

i'm a pretty conservative driver--i mean, i don't speed or accelerate quickly or anything like that, so i don't think my driving is affecting it a ton. hopefully it'll get a little better as the engine gets broken in!

Try always driving with the ECO on light...Your MPG will go up.

yeah, i do when i can, and as long as you're going around 60 on the highway it's possible--just tough in the city because you're constantly stopping and starting.

though i did just fill up and with a mix of highway/city i got almost 17. not what it should be, maybe (a lot of the mileage was highway) but improved from a couple of days ago, so hopefully it'll continue as the engine gets broken in.

I have a 2011 with 2500 miles. If all of my driving is suburban I'm at 14mpg. If some highway mixed in it's been 15-16mpg. Like others have stated I didn't get this vehicle for superior gas mileage but this is still very disappointing.

I came out of 2004 Mazda6 sport wagon that was rated at 19/26 mpg and, although gas prices aren't the same as they were 7 months ago when I got my 4x4 Liberty Renegade, my fuel econ is only about 1 mpg lower in the Jeep compared to the Mazda doing the same daily (mixed) drive as before. Considering the Jeep is almost 1,000 lbs heavier that's not terrible.
Unfortunately I do a lot of driving so I've racked up over 14K miles in the 7 months that I've owned it. I track fuel economy pretty meticulously and just looked back at my log and can see about 1.5 mpg improvement between brand new and now.
I too was a bit disappointed by being able to see the improvement and compare head-to-head has taken some of the angst away. It could be worse, we could be pumping premium!
