What could be causing poor fuel mileage in my 2006 Jeep Liberty?
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, V
