Okay I know that this topic has been beat to death but I seriously can't figure out why my JK acts like the gas tank is a shot glass? Here are the specs:

1) Brand new JK with 1030 KM or 643 Miles.
2) Right now I have 303 KM or 190 miles on it with less than a 1/4 tank.
3) 6spd JK and I drive like an old lady with people up my ass all day.
4) My commute to work (M-F) is 80% Highway in 6th gear @ less than 2200rpm.

Bottom line is I am lucky to get 340 KM or 213 miles out of a 70 litre tank? Now I have used the search button on this topic and saw that some guys JK's gas millage has increased with age but....


On a side note: I didn't buy this JK because of the amazing fuel efficiency.

I don't know the metric conversions, but i get 10.5 mpg average with an auto 4 door.

 

I'm not sure why it's so bad (any who have posted so far). Meter shows me avg around 19.5mpg. And that shoudl go up a bit after 1 - 2K miles on the engine I am told, and I have a heavy foot (and less than a 1/5th of my miles so far have been above 50mph). It's not great mileage in a Jeep, but I'm where I should be, don't know how some folks get it so bad.

Another member posted a while back something like... The aerodynamics of the JK is like driving a brick with wheels...

Consider your mods, bigger tires, bumper and/or skid plate weight... I'm lucky to get 10-12mpg.

But I still love my Jeep!

 

The thing is a boneyard stock Saraha! After using the search button on this topic, I have yet to find anyone that is buring anything close to what I am.

340 KM or 210 Miles per tank is BRUTAL.........but fun.

210 miles per tank is about what I average

 

Wow, I hope it gets a better for ya. I have a pretty close comparison here. Stock 2door JK 6-speed with the tiny 225 tires that I've only had about a month and have about 2200 miles on it so far. My commute is 120 miles a day of all highway and I'm guessing we have the same gearing because I'm running about 2100 RPM at 70mph in 6th gear. I've only run a few tanks of gas through it, but the mileage has been getting better.

15.5mpg.......18mpg.......19.5mpg......21.5mpg.... ..and my last 2 tanks of gas I ended up going 350 miles on 17 gallons of gas which puts me at 20.5mpg.

Just for reference......my fuel light kicked on yesterday at 306 miles, then I drove it another 44 miles and filled it till the pump shut off right at 17 gallons. I don't top off my tank.

 

i forgot to add that i am running 33's on stock steelies with 3.21 gears

 

I got 225 miles per tank on my 2dr when it was stock. Sometimes less, never more.

 

Winter fuel additives? I know down here in Tennessee, we get a winter blend that kills fuel economy, I think the computer needs a few tanks to adjust, and then it is still not as good as it is with the summer blend. I would imagine, you guys have a lot of additives to keep moisture from freezing..
