Replying to: 2006liberty4x4 (Aug 22, 2008 6:13 am) " I would hope "Jeep people" would want a good off road vehicle yet still not have to pay the gas bill of a V-10."   No disrespect intended, but you don't sound like a "Jeep person". A Jeep person wants his/her off road capabilities to be paramount.   It is possible to make compromises in off road abilities, but that is not what Jeep is known for. The only non "rated" Jeep is the Compass; I drove one and got about 23 MPH highway (rental). That vehicle was a crossover from the Caliber.   If you want a "part way" off road, there are plenty of candidates - they generally have part time AWD, though some of them lock the low gear. CR-V, RAV4, Grand Vitara, etc. come to mind. And of course there is the Subaru family, which has great 4WD.   In order to make the Jeep sturdy and thoroughly off road capable, they have to make parts a certain way, build stuff a certain way. That "way" is not for fuel efficiency.

Getting back to the original topic....   I bought a used 2003 Liberty in August 2006 with about 40k miles on it. I now have 128k miles on it (I drive a lot) and overall, I have seen around 17 to 19 mpg. I just put a large Thule cargo box on the roof (to make up for what has long been my biggest gripe with the Liberty: insufficient cargo space) and was worried somewhat that it might adversely impact my fuel economy. After three tanks, I have calculated the average MPG with the box, loaded with gear at 18.47mpg. I was actually surprised it was that good. I guess this is a testament to the aerodynamics of the cargo box, more than anything to do with the Liberty, but I thought it might be good information to post...in case anyone else is as frustrated with the cargo area of their Liberty as I was.   Btw, I was also carrying two mtn bikes on a spare tire mounted rack, as well as a good load of gear inside the Jeep.This fuel economy is very comparable to what I have been getting the last two years or so.   Interestingly, before I bought the Liberty, I was given another liberty (a 2005) as a rental, and it must have had a larger tank, and gotten better mileage. I think when i tested it, I was getting over 20 mpg, and going over 400 miles on a tank of gas. With mine, I only occasionally manage to get much over 300 miles before my fuel light switches on. I have noticed that the 2005 felt lighter and not as solid as the 2003 I ended up getting, so maybe there is a weight factor there. Replies to this message: jayrider (Jul 04, 2009 12:21 pm)

Replying to: gpshunter (Jul 01, 2009 2:00 pm) only have 26k miles on my 03. No problems -- put on a set of bilstein shocks - great ride improvement. If you 've gone 128k miles and still happy, looks like I have 25 more years of happy motoring. Mpg is low 20's on the interstate 65 mph. Short trips around town -- 15-17mpg. A little worse in winter of course.
#58 of 58 2006 liberty mpg's by jeepfreedom Sep 09, 2009 (5:17 pm)
Just bought a 2006 liberty 4x4 in august with 41,000 miles. It is a 6 speed manual.   I have now filled up 6 times. here are my mpg's   20.80 19.57 20.88 20.22 20.22 21.57 (about 90% highway)   The engine is unmodified. I do plan to switch to synthetic oil and a new air filter when the next changes are due.   I would say most driving is about a 70%/30% split highway/city but I mostly drive 75-80 MPH on the highway.
