Heh, heh, congratulations! But its pretty sad that you have to work that hard to get 20 mpg. Did you try overinflating your tires? That's been the most effective thing for my Mustang on long trips. I'm interested in the Liberty's cousin the Dodge Nitro. Its supposed to be rated a little better on gas but I'm not sure why.

I have a 2006 diesel and I’m only getting 22mpg if I drive it right. Is there something wrong with my jeep liberty crd 4x4. After 19K it isn’t getting better. Friend of mine regularly gets 25mpg on his 2005. It is expected to get 22-26.I do my calculations myself. Thanks

Ask your friend if he fills his tank with imperial gallons instead of American gallons. 20 miles per American gallon would equal 25 miles per imperial gallon. (Because the imperial gallon is bigger.)

New "07 Liberty Sport 21mpg first tank full. by clintondee

I was worried about buying the Liberty instead of the Patroit because of gas mileage issues. I figured the Liberty would get around 18mpg and the Patriot around 24. I steered my wife towards the Patriot but she would have no part of it. She wanted a "real truck" and once she drove the Liberty it was all over. The liberty does have the ability to go through much deeper snow the the Patriot and is a real truck. After filling up with 360 miles on the odometer I figured out that we got 21 mpg on our first tank of gas. It stayed at 21 mpg for the second tank now also. This is a mix of 50/50 city / highway driving not exceeding 65 mph or 2000 rpm's to often. The transmission is great and offers a lockup gear so you can let off the gas pedal a bit and watch the rpm's drop a few hundred to 1600 and still be going 60 mph. I think thats the trick to getting good mpg out of the Liberties. At 21mpg I'm glad we went with the Liberty instead of the Patriot and before it switches over to the Nitro style.

have 04 3.7 auto 87k miles if i drive 70 according to my gps i get 18 mpg manual calculations and filling up till gas can't put any more in. if i drive 55 and around 1600 to 1700 rpm with cruise 1 get almost 23 mpg which comes to almost 12 to 15 dollar saving on a tank of gas didn't take to much convencing and thinking about installing a air cell throttle body won't be much but anything helps maybe headers and new exhaust any test results from anyone i would appreciate. would a chip help?

We just finished a trip of about 3,000 miles in our 2006 3.7L Liberty. Averaged 24.5 mpg driving an average 65 mph. And around town in general use it's been getting 22 mpg (summer) and 20 mpg (winter).

Don't want to dampen yr. spirits on the liberty but I have never been more disappointed in a Jeep in my life. The Liberty was our 4th and the mileage was beyond miserable. Can't dispute what people are posting but did talk with other local owners and no one was getting this kind of mileage. Jeep/Chrysler/Daimler was beyond worthless to work with. Although the Corp. Product Support group finally eluded to an issue, they would not assist in doing anything to improve the mileage of our vehicle. Within a year and at approx. 6,000 miles we traded for a Hyundai Santa Fe. Amazingly different vehicle and double the mileage. It does what they claim it will do. Hope you have better success then we did. Was not wanting to trade but could not tolerate the issue any longer. I'm totally turned off on Jeep and Chrysler product at this point.

I am new to this group [just added]. I have not seen anyone discuss the practicality or usefulness of updating the fuel injection system [with a system such as Advance Auto's K & N K&N Fuel Injection Performance Kit] which may improve the MPG stats. It costs about $260 if you install it yourself. I do not know the impact on the warranty it may have.
