Mine gets 16.5 city and around 18 hiway, with the only mod being a K&N air filter.

Just an FYI, but this is a forum that takes sometimes days to get a good reply. I said that because you seemed disappointed that no one answered you between 2:30AM and 9:30AM. (I was asleep most of the time)

What kind of mileage are you getting?

I get about 15 miles to the gallon in the city. If you are concerned with gas mileage i would suggest purchasing a throttle body spacer and a K&N.

I haven't had my TJ for even a month yet.
My specs are below, besides that, I have a K&N air filter. I haven't used a full tank on just street driving yet but I anticipate around 13 mpg, which is mostly freeway (not gridlock) driving. I'm not really satisfied with this number, I will live with it if I have to, but I will see what I can do to make it better.

A 4.0 isn't going to get better than 17 unless coasting downhill. A 2.5 might.
Jeeps are bricks on wheels. If you want gas mileage buy a HONDA.

I get close to 20 pretty regularly. My 97 TJ is bone stock, 30" wheel package, 5spd.
Nothing fancy as far as plugs, Champion Truck, mostly highway driving, the only 4 wheeling I get to do now is pulling up stumps and dragging silly people off the beach with their whannabe 4 wheelers.
I've got close to 80,000 miles, maybe there is a break-in period???

I'm going to throw up the B. S. flag on getting close to 20. 15-16 is close to 20 but you aren't going to get any better than that. better get a new calculator.

All this talk fo fuel mileage reminds me of the 8cyl Camaro I had when I was a kid. My grandfather was a really good mechanic and I asked him how I could get better gas mileage. His reply, "Lie" Just my two cents worth.

If I attach the flag to my attenna I bet I'll gain at least 5 hp!
I will say on average, I get 19-20 mpg. 40 miles all highway each day to/fro work.

I have a 98 2.5L. I get 19-25mpg with an average of about 23mpg. I would love that extra power but the extra cast up front and then for the life of the vehicle was a shock. I have some friends with the 4.0L who put up their BS flags all the time and try to tell me they get even better milage than I do. Now I finally have the truth. I think they are just trying to make themselves feel better.
