I expected 16-18 mpg's. I know it is a jeep and you don't buy one for the fuel mileage, but 13-14 mpg on the highway is ridiculous!! My 1997 Ford Explorer with V8 All-Wheel Drive gets 14-16 mpg, and the 1998 Jeep Cherokee was getting 17-18mpg when It was wrecked. The dealer says they checked everything, but are not able to give me an answer other than that is normal. I have read a number of posts here and elsewhere and haven't found any with similar fuel mileage. I am wondering what can be checked, or did I just get a lemon?

I have always had SUVs, although they were never as new as this one. None of them had this poor of fuel mileage, so is the quality of newer vehicles declining as is the case in other types of products? It has about 4000 miles on it, has Amsoil synthetic oil, dealer has run EEC test with no fault codes. I have driven my 97 explorer and 2006 Liberty on alternating days and checked fuel mileage and the explorer consistently gets 1-2 mpg better. It is older, heavier, V8 vs V6, 131000 miles vs. 4000, it just doesn't make sense to me?!?

The overinflated EPA estimate is 17/22. I am getting 13-14 on the interstate, which is 8-9 mpg less or nearly 50 % less. I have read the EPA is revising its testing and that the hybrids will take the biggest hit and lose 30-40%, my liberty is lower than that. I understand how the EPA estimates are inaccurate and that driving conditions affect mpg, but my concern is the comparisons of my newest vehicle I have ever owned and the older ones that have/are getting better fuel mileage. Also, I understand that there may not be an answer other than I got a lemon.

There quite possibly could be something wrong with your air/fuel mixture and it would be difficult to detect if it was a computer problem. Having the dealer re-flash your PCM could fix it. Also, check for proper tire inflation and that your air filter is clean. Make sure your oil is clean as well. Other than that, if everything has been checked you may have some other problem with a sending unit or a clogged up or malfunctioning sensor and don't forget that a lot of your mileage depends on your driving style and how high you have your RPM's on the highway. Give that a shot and see where it gets you...easy things to start with for now.

Maybe a heavy foot on the accelerator.
The fuel estimates that are posted on new auto stickers is an estimate of what the manufactures got when several of the same vehicle was tested. Also US manufactures use only one type of gasoline in its test. Chevron gasoline is the only fuel used for the mileage test.
Jeeps are not and will never be an SUV. It is a Jeep. SUV's want to be a Jeep, but never will be. Jeep started the four wheel drive craze after World War II.

I could be off base with this but it might be worth getting checked out. My 2003 Chevy Venture's fuel guage went nuts a couple of days ago. I stopped at a dealer and they said it was the sender had gone bad. When I got home I found on the net a huge set of problems concerning GM fuel sending units. The root cause is that the sender is reacting badly to aftermarket fuel additives and to ethanol. If you use E85 your milage might be right on, only your guage might be giving you faulty readings.
The only way to know for sure is to fill the tank and drive it till you run out of gas (have a gas can ready to get you to the station). If you go 5 or 10 miles after the needle drops below E your guage is good. If you go 50 to 100 miles you'll need a new sender.

Definately check your tire pressure, and your air filter. I put a k and n air filter in my car and the mpg went up from 22 to 26.
The cold weather makes cars use more gas too. So when it warms up it should get better. My car right now is only getting 22 because of the cold.
Use your cruise control on the hwy, and dont take off in a flash. Nothing uses up gas like slamming on it all the time.

The Government has revised the 2007 fuel economy ratings downward . in some cases more than 4mpg. the new ratings take into account that you don't drive on flat roads with no wind. So don't feel bad , The ratings are optimistic on pre 2007 models

Have you checked the air filter? Also doesn't the MPG depend on the conditions in which you are driving, such as hills & how fast you are driving? Remember the MPG listed is for optimum driving conditions, NOT actually driving situations.
