i have an '07 v6 grand cherokee laredo and i'm also disappointed with the mileage. i was expecting it to be under the sticker (which was something like 18/22) but if i avg 13 miles a gallon on a tank of gas i'm ready to celebrate. i only have like 3500 miles on it so hopefully it'll improve w/more miles but i'm not expecting it to improve considerably...

I love the torque above 2,000RPM. Jeep needs to add 1 or 2 ratios to the transmission. The Mercedes GL gets up to ~27mpg with the same engine.
I can get 25mpg ( UK gallons) as a general rule from mmy 3.0L CRD commander. if I drive her hard though its about 22.

my wife can get nearly 30mpg from it but I don't know how as she drives it harder than me

My 07 V6 has the same mpg, I am getting around 13 miles per gallon, mostly city driving. My old 1993 4.0 L with over 150k miles was getting almost 15 mpg.

Right now I am getting 17.9mpg with a V6, a lot of highway driving (but no use of cruise) but also a fair amount of driving up and down hilly terrain. That was with the reset done when the vehicle was picked up...I will try resetting while on the highway and see how the next couple of tanks fare.

When I had my '97 ZJ/4.0 2x4 fully stock, it gave me average 17MPG (US) city/highway burning 87 octane. After upgrades to intake, ignition, and exhaust, burning 89 octane, my average went up to 20 MPG and I had regular 24MPG on highway trips, staying right at the posted speed limits (usually 65MPH).

Put the whip to the horses (90+MPH) and she'd drop to 14 MPG (or lower....)

It matters what fuel you burn, how much air is in your tires, and what the weather is doing.

My brother has an '04 WJ Overland 4.7 V8 2x4 fully stock, and gets somewhere between 16-17 MPG average, I believe

Reviving an OLD thread from all the reading I have been doing since I joined. To chime in on the V6 performance on an 08 WK I average 19ish combined on each tank of gas. I have gotten as much as 415 miles out of one tank and as low as 300 so it all varies. I have recently moved and the commute is shorter, but I have seen 23 MPG's averaged on the highway. City is about the 16-18 range for me and I'm a pretty light driver. My biggest complaint is that I didn't get the V8!!!!

I dont know why all of you people are so angry on fuell consuption? All of you drive 2,3 ton suv with 3,7 l or larger engine. 20-23 mpg on highways and local roads are peak for that size of vehicle.Buy your self vw jetta or golf diesel and stop complaining.I see a lot of smaller cars like bmw's and mb's with 3,2 and 3,0 l petrol engines with same consuption - about 10-12 litres on 100km. Dont need to mention that those cars have much more aerodinamics than brick shaped Jeep...

My 5.7 gets better than that towing our boat at 65-70 mph. I think the hills have something to do with it, I don't think it really evens out.

I average depending on time of year 11.9-14.1 in stop and go city driving...

I have seen as high as 23 mpg on the highway, though normally it's closer to 19.

4.7: When I set the cruise control for highway driving, I average 23 mpg. When I putt around town for the week I typically get 17ish mpg.
