This is a follow-up posting to the 22 Jun 09 one I wrote. I've since run two more "tests" on my 2004 Liberty's gas mileage, and the results were 20.0 and 19.3 MPG respectively. These results are a combination of highway and city driving (perhaps slanted a little more towards highway). Referencing www.fueleconomy.gov, I should be getting a combined MPG of 19. Therefore, my Jeep is performing where it's supposed to be.
For those of you getting MPG's in the 13-15 range, are you using the 19.5 gal fuel tank capacity for your calculation? If you are, I would verify that when you fill up your next tank of gas, that you can actually put that much into your car. All I know is that the most I've been able to fill my tank with (once the fuel light comes on) is 59.1 litres, or 15.6 gals.

Try the gas mileage test when the weather is cold, like below 60 or 50 degrees. It seems like the lower temps make it eat gas like a hog, I am talking about 10 to 11 MPG. You folks who live in warmer climates are probably get better MPG because it never gets that cold.
I think the tank size might be smaller, I put in 6 gallons and it equaled about 3/8 of a tank. So if I calculated right, it would be a 16 gallon tank. It seems to be very sensitive to cold weather, I think the programming is crappy or something in the computer for adjusting to temps.

I just bought a 2006 Jeep Liberty 3.7 liter V6, and it does in the city 9 mpg! I know it should do 17-18 mpg in the city, this is not normal, only a little detail that is irritating me!
Did you guys find any solutions to the problem?

I just wanted to add that I have a 2003 Liberty Sport 5 speed. I live in Canada, Ontario where our temps can range from -40 to 104, depending on the time of year, and it's never dropped below 20 MPG, other than offroading, and that includes towing my 18ft boat around on its stock air intake, exhaust and regular oil.
I have no complaints about the Jeep, and am always impressed by how much it can do compared to my friend's Rav4s and Escapes. Yeah, their gas mileages are better, but that doesn't help them a lot when they're stuck in a snow bank and "the gas guzzler" has to pull them out. Just keep in mind what Jeeps are built for, and what their competitors are for. You want gas mileage, by all means switch; you want a car you can always count on to get you through any conditions, stick with the Jeep.

2nd Jan 2009, 20:26 - I'm not sure how you are getting such poor mileage with your Liberties - as I have owned 3 Liberties (currently a 2007 Limited), all equipped with the 3.7 liter V6. I've also owned 3 Wranglers (both YJs & TJs), each equipped with the 4.0 liter inline six, and my wife owned a 1998 Cherokee with the 4.0 liter inline six as well.
I couldn't be happier with the gas mileage of my Liberty, as I get mid 20's highway, and high teens in town driving. My combined overall average is right around 20mpg. This may not be great by economy car standards, but is far better than any of my inline sixes got (I think the inline six is one of the best engines ever produced by the way).
The mileage I am getting with my 2007 is slightly better than I got with my 2004, and pretty close to what I got with my 2005.
Again, I can't understand how you are getting such poor mileage, unless you are driving with a lead foot or are constantly in stop & go traffic - still you certainly should be getting better mileage than with a 4.0 inline six or a V8 for sure.

I own a 2004 Jeep Liberty, and actually thought that there might be a hole in my gas tank. The mileage stickers on the car when I bought it, appear very inaccurate and deceiving.

I would suggest you drive with a lighter foot if you really thought you had a hole in your gas tank.

Again for all those who are complaining about the fuel mileage of their Liberties - Stop & go driving, and short trips, eat gasoline - also living in a cold climate and leaving it idling in your driveways to warm up for 15 minutes also is using fuel. I've owned 3 Liberties - I am getting 23-24 MPG highway,and high teens in town - I cannot complain at all about those numbers. Seriously folks, if you want higher MPG, purchase an econobox or a hybrid such as a Prius. A Liberty is a fairly heavy SUV that will get you through virtually any weather and road conditions. You won't get that in a 40 MPG tin can.
I'm very happy with 23-24 MPG highway. There are plenty of vehicles that do much worse.
It seems to me that not enough people do their homework when purchasing a vehicle, and then complain when it turns out NOT to be the right vehicle for them.
