Not much I was actually looking at them recently and decided against it because the mileage and a mechanic told me they have transmission trouble like the Ford Explorer
Lisa Marie!!! Should ask me that directly!! I'm a car guy!! Anyway, 1998 probably has high mileage on it, which reduces MPG a bit. If V8, will get 12 around town and 15 on highway. If V6, add 2 miles per gallon to both figures. They drink a lot of juice.
I actually own a 98 durango 4x4 with the 5.9L. Jim is close to right. I average 13-14 in the city and I average about 18 on the interstate setting the cruise at 70. They never came with a v6 to my knowledge. Way to heavy for it.
I also agree with Mike, I also own a 98 Durango 4x4 SLT with the 5.2L and I avg.15-16 city and I avg. 20-23 highway also setting the cruise at 65-70. Just monitored with the computer a few days ago on a small trip that I took.
