This discussion is for reporting on your Liberty's gas mileage. Please mention your odometer reading and your driving style, city/highway mix or anything else that will help others compare their mileage to yours.

#3 of 62 2002 Liberty Limited
Aug 01, 2006 (9:05 pm)
In response to some of the discussion regarding MPG. I own a 2002 Liberty Limited with the 3.7 and I get 22 MPG in mixed driving and I get 27 MPG in the highway. The only thing special I do to my Jeep is use Mobil 1 synthetic motor oil. I have a limited slip rear end so I never loose traction as some have posted. I just heard about the lower ball joint recall and realized I missed the lower ball joint recall back in 2003. Guess I should have that fixed. I haven't had any problems what so ever with my Liberty, I love it!

beniker: Please excuse my bluntness, and you might even say rudeness. Having lived a good length of time, life teaches a lot of things. One thing I am able to spot is a mistake or a miscalculation. I am very positive you have made an error. There is no way you could achieve you gas mileage you claim with a 3.7 V-6 with a 4 speed automatic transmission.
I am sure it's fun to joke with people. I could say my CRD liberty gets 37 mpg too, but everyone knows that's not true. Just as we all know what you have said is a joke as well. And you caught someone who bit into your hook.

On my 03 Liberty I average 15-16mpg strictly in town with some stretches of 2-3 miles of 45 mph cruising a few miles between stops. If I add about 50% interstate it moves to 18 mpg---rarely any higher. Straight interstate at 60-65 mph I can average 22-23 mpg if conditions are favorable. With a headwind or rain-- it drops to 20 mpg. There have been trips where I have a bit of a tailwind and keep it at 55 mph where I can get to 24 mpg for a stretch but that's the best I've done in three years. It can help a bit if you can fuel up with
%100 gasoline and avoid the ethanol blends but that's about all we have around here.
3.7 with automatic is what I have. I don't usually put much effort into driving with super efficiency but if you are really careful, you might be able to do a bit better.
#6 of 62 About the 6 speed manual
Aug 30, 2006 (8:43 pm)
Well at least there's a little life over here so I'll repost my message from the main board... (Cleverly rephrasing it so it sounds like a question about gas mileage )
I was wondering if anyone can comment on the 6 speed manual version of the Liberty? Such as what kind of mileage do you get?
Also was wondering about how it shifts, whether the clutch engagement is touchy or progressive and what rpms are normal for highway cruising?

Don't have a stick but I do have a story to relate in this regard. I was in the market for a cheap ride in 1992 and ended up deciding on a plymouth / dodge sundance stick with air. The deal seemed pretty good back then so I went to two large dealers and drove six cars identically equipped. I did that because I wanted a car that shifted, idled and accelerated smoothly right away. Even though these cars were identical, my test drive efforts were worth it. The cars with the most attractive colors unfortunately were poor drivers--hesitation-vague shift points etc. I would have chosen poorly. The dealer said that once I bought it they would correct all concerns. I didn't have to get involved in that fiasco because one car stood out. It was bright red -- not my first choice but it drove and shifted way better than the rest so I bought it. Kept it nine years and 114 k miles and only had issues with the a/c the last 3 years.
My advice--- go drive at least two or three Liberty stick shifts and see what you think. Previous posts don't seem to indicate a great deal of mpg improvement vs automatic -- you save bucks when you buy but lose big when you sell.If mpg is a big consideration in your choice of cars, the Liberty won't make you happy. It is what it is -- a heavy little truck that I find a lot of fun to drive. The other problem is that you have to settle for part time 4wd with the stick which limits its usage to extreme conditions like off road and very poor traction surfaces. I like the full time option a lot.
Go take a few test drives and let me know what you think. The most important opinion on this issue is yours. Have fun!

I have an '05 Liberty Limited running synthetic oil, a K & N air filter, and Goodyear Fortera tires. I'm an easy driver. I bought it in May of '05. It now has a little over 26,000 miles on it. In that time it has averaged overall 18.4 MPG at an average 41 MPH according to the elapsed time. I drive predominately hiway with some city driving. My guess is that it gets around 15 or so around town and strictly on the hiway between 60 - 65 MPH it will get 23 - 24 MPG. If I get up to 70 it will drop to 20 MPG. If there is a headwind, side wind, rain or cold weather it will lower the fuel economy accordingly. I can't say that I'm disappointed with the fuel economy because I knew what I was getting. I have 4 wheel drives since the 70's and for its weight the Liberty does well. I would much rather drive it than an econobox.

libbman: I am pretty sure you are judging what you fuel miles per gallon is by what the electronic readout says in the overhead information center says. Having had a Limited I can assure you this readout is very far off. The only real way to know what your mpg is requires you to do it the old way. Fill the tank up as much as will go in. at the next time to put fuel in fill it up all the way. Now form the current mileage subrtact what the mileage was when you filled it us the time before. Now devide the gallons into the miles drivem. That is the true miles per gallon. Our 2005 Limited Liberty got a pretty consistant 15 to 16.5 mpg. The very best was 18mpg. There is just a very slight chance with a good wind pushing you, than 24 mpg could be reached. The 3.7 with the rear end they come with just won't get 24 mpg if even that. Now our Liberty CRD gets 26.4 mpg and that's doing 73 mph with the air on.

Actually I did figure it out manually. I had 26,076 miles on the odometer and I put in a total of 1418.817 gallons since I bought my '05. That figures out to 18.378 MPG. I keep records on a monthly basis. I have checked my overhead and it comes out approximately .1 to .3 off per tank and that could depend if I try to get that last drop in or not. I have had 4 Jeeps with overheads and this one is the closest to acurate. My odometer does read a little slow, about 1 MPH slow and that is measured against my GPS.
