About 300+ miles per tank, and the RPM range at about 2300 at 65.

I recently changed my plugs, and got 200 miles at half tank, from full to the neck, but drastically dropped off after that. I got about 350 miles from that tank, not a lot.

I have a trip to Fort Leonard Wood coming up this August, and I know it's going to be three about tanks down, and about three back, thus costing me $240.00 in gas alone.

Geez you guy's are getting low mpg's.When my KJ was still stock height with 225/75's and basically no armor(only MOPAR skids) I'd pull 400+ on a tank of gas easy with 50/50 highway/city driving.Now I get about 100miles to 6-7 gallons(fill up every sunday) with 100% city driving but that's lifted,265's,and 1500lbs more weight.


Oh couldn't tell what my rpm's are at 65mph,never drive 65mph since it is in the bog point in the torque curve with my tire/gear combo.I always's go at least 75mph and I'm only turning 2500rpm's at that speed.

I get low miles because PA gas has Ethanol in it, at least 10% during summer months, and we pay MORE than some states. Ethanol is worse for MPG than regular gas. I used to go to Ohio a lot (friend), and fill up there before I came home. I got a lot better MPH than with PA gas.

Still I would probably get 400MPH all highway, and I will see come August 19th...

That was in South Dakota with 10% ethanol also,I always get better mpg's and better power(get to run 93 octane in SD with 15% ethanol) then I have gotten anywhere else from 100' altitude to 10,000'+ elevation.

I averaged 22mpg, or over 400 miles on the last tank. I guess i don't drive as spirited as some. I did calculate as high as 24.6mpg on one long trip. The tach sits around 1800-1900 rpm at 65mph.

Guess i'm doing a lot better than others. I always take off slow, use the cruise control, etc.. But when i get in a hurry i can average 16-18mpg on a bad day.

I run 1,800rpms at 60mph, around 2,000 at 65rpm.

Per tank I get around 250-300 city/interstate(75mph) mix but I only get 15-16 gallons in the tank.

dont know the RPM ,dont drive it enough at that speed
at last check we were getting 15 city and could get 20 highway
that is stock gears and 245/75 MTR's
I am waiting to see how much better the 255/70 Yokohama AT's do
lighter ,shorter, and less rolling resistance

I am thinking that I should see 16-17 city and the same jump highway

As far as mileage, with stock size tires I'm lucky to see 16.5 in the city, highway I could do 22....:)

I have the 225/75's and today I was just hitting 2k rpm's at 70mph. On average I get 14.5 mpg's, but I fill up at the half way point of my tank, and I usually get around 240 miles to a half of tank.
