Where there's a will, there's a way - tank swaps have been done...

But Jerry cans look more awesome! Talk about a target for thieves though... They are even big and red like a bullseye...

Yeah your 3500 rpm shift points are gonna burn some fuel.

im going to agree with mike134 on the shift points. I only have the 3 speed auto with no over drive. around town im ok on gas...the minute I hit the highway and whine out third gear, around 3200-3400, I can literally see my gas guage dropping.

With bumpers, a little bit of armor, recovery gear, 35's, and the same basic modifications you've done, I average like 14-16 depending on how I drive it and the speeds I stay at. It's mostly city with short highway trips, and I get around 15 out of it most fill ups. I've never been super concerned about it, but now I have a 4 cyl honda that saves on gas most days

I get consistant NO LESS than 20mpg with road tires, all stock everything. I often get close to 30 when straight hiway driving. However, speeds don't go over 50 much and 60 rarely.

I get around 16mph with 33's, a soft top, stock gears, and no armor. I usually shift around 2500rpms.

I got somewhere around 12-13 with my 4 cyl. I didn't really care though, fuel economy isn't why I have this vehicle. Mind you my driving is 90% city stop and go, and my shift light is usually the red line

I have no idea where I shift... I haven't gotten around to fixing the tachometer since I bought the thing. Its mostly worrisome on the highway, having no idea how fast the engine is cranking...

If the oil pressure and the water temperature stay fine then IMHO who cares?

You also need to offset your trip meter if your speedometer has not been corrected. I run 30's on my 95 and the mileage offset is 1.11 x trip meter / gallons used. I am between mid 18's to almost 20 if I am driving with the windshield folded a lot. (You can gain a good 1mpg like that!)

I am running a 4.0 TB, & a 2.5" cat back on an otherwise stock motor with 188k

Close to 30mpg in a Jeep?? Call me a little skeptical, but that's more than a little optimistic (even at 50-60 mph).

i get 14mpg with 35s and 4.10s in my '95 4cyl. ive done all the mods to it and it definitely improved over stock in idle, mpg, and power. for a few hundred bucks (not all at once) its a great bang for the buck.

4.0 TB , Ford 19lb injectors, CAI, Taurus Efan, and soon im going to move the intake air sensor to see if i get another improvement

I've never measured my mileage. I figure there's nothing I can do about it anyway since I've got all the regular maintenance stuff up to date.
