I've read elsewhere on the Interweb where other Liberty owners are reporting bad MPG ratings. I managed a best of 23 MPG Highway on a 700 mile roundtrip recently. I would expect a vehicle this size/engine to be in the Mid-High 20's MPG Highway. What are you folks seeing on yours ?? |

Compare and contrast the gas milage of other 4200 lbs vehicles, you will find that the MPG will be about the same. The only stand outs would be diesels. |

That is our big downfall, weight. If the KJ weighed the same as the Cherokee, we'd get mid 20's easily. The Cherokee is around 1,000 pounds less than the Liberty. |

Just got back from the beach last night. Good 200 mile trip, one way. a/c on, CC the whole time and I got a little over 20mpg. I usually average 13-14mpg around town, which 98% of my driving is around town. Got about the same results on the way back, went through some heavy thunderstorms so I had to take the cruise off, which yielded about 19.5mpg, still awesome for a two ton Jeep with the a.c on....lol |

The Liberty is kinda a porker. It weighs about what a 1/2 ton truck weighs, and gets mileage like one... |

Ditto. Keep in mind that the KJ is kinda like a 4,000 lb brick on wheels...it's heavy and not very aerodynamic, both of which hurt its mileage. It's also pretty peppy and handles well on the road so I suspect most people drive it in a "less than efficient manner." I definately have a heavy foot. It's Jeep, what do you expect? If good mileage was important to me, I'd get a RAV or one of those Honda things.

I wonder why the couldn't have least offered us a slightly bigger engine- maybe a V-8 version. My 96 Tahoe weighs (curb weight) 4731 lbs, but gets 19+ MPG- easy 20 on the highway. My lifted Libby gets 15+ on a good day 
Libby seems a touch more aerodynamic than the Tahoe, has smaller tires, and definately a smaller engine. Could the extra Torque that the V-8 provide better gearing for the Tahoe? |

I just turned 20,000 miles and did a 120 mile round trip on the interstate. Flat as flat can get.....in between Bloomington IL and Champaign. Yes Im lifted, bigger tires and all but Im used almost a half a tank of gas round trip. That's 14 miles to the gallon on the interstate. Before lift and tires I got 18. I get 10-12 miles to the gallon in town. --BlackOps PS : Getting ready to add the All J skid so we will see what that does..... |

At a little over 12,000 miles on my lifted '04 Sport, I get 12-14 city and 17-18 highway. The best it has ever gotten was 20.5mpg before lift, and that was on a 250 mile one way highway trip with the cruise set at 70mph.

PAT, What mods do you have on your CRD? If none, that is one heck of a heavy diesel engine! |

Maybe it's driving style or something, but I just took a 1400 miles trip across county towing a 3000lbs trailer and averaged somewhere between 15-16mpg. I'm also lifted w/ armor. In the city I can typically get almost 18 mpg w/ mods but I drive like an old women most of the time. I've seen my milage easily go down to 15mpg by just having a slightly heavier foot. On the highway I can get 22mpg if I stay around 70mph w/ mods. |
