Gas guzzler - not really

Yesterday I attended the funeral of a cousin my age who had died of MS. Unfortunately, funerals are one of the few times we get to see extended family. I noticed that one of mGas Nozzley other cousins was driving a Grand Cherokee similar to mine. At the funeral luncheon afterwards, I said, "I see you are driving a Grand Cherokee. Me too!" I was expecting her to tell me about how much she liked it, since I like mine so well. My usual response from people is that they really like their Jeeps. However, her response surprised me. "Oh, my gas guzzler," she said. So we swapped comparisons.

For some reason, her gas mileage is quite a bit worse than mine. She said she is usually between 13 - 15 MPG. A while back she drove across Nebraska at 60 MPH and only got 18.5 MPG. That is the highest she has gotten. I've tracked my MPG since I bought mine almost 2 years ago. I've gotten as high as 22 MPG, and average 18 MPG overall including highway and city driving. So I'm doing much better.

Our engines are basically the same, both 6 cylinder 4.0. Our options are similar. I can't explain it. Perhaps her driving habits are different. Maybe, as she suspects, something isn't quite right with her engine. For some reason, there is quite a difference. I realize 18 MPG overall in no way compares with sub-compact cars getting in the 30s. But for the size and features of my Grand Cherokee, the gas mileage I give up is worth it to me.

I can relate to your cousin. My 2003 Jeep liberty (3.7L) is getting 13.0 MPG at 2/3 city driving, normal pace! I've NEVER gotten better than 18.5MPG even on long highway trips down south on flat lands. The thing runs great but sucks the fuel like a full size truck or worse!!! Any ideas what the deal is here???

I don't know, Justin. My wife drives a 2002 (3.7L) Liberty. She has averaged 18.6 since we got it with about 2/3 highway driving. She has gotten as high as 20.6 although we've never taken it on a trip. I've averaged 17.9 overall with my 2003 (4.0L)Cherokee with 2/3 city driving, getting as high as 20.8 on a trip. Maybe it is our good Nebraska air!
