Guys, long story short...

Owned jeeps for 20 some years before buying what I found to be the worst ever SUV on gas in the form of the Land Rover discovery Series 2. That thing was getting between 10-12 mpg. I sold it after 4 years of ownership, thinking that I would never buy a vehicle that bad on gas ever again.

Fast forward to my 4 months old 2013 Jeep JKUR 10th anniversary with now about 2500 miles.

Stock suspension, 3.73 gears, 33 inch 285/70r17 Duratracs inflated to 36psi, speedometer corrected with flashcal and calibrated with a high end GPS (needed to set my tire settings at 31.5 inches tall for speed and mileage accuracy).

I drive it like a grandma, start slow and always keep it in the ECO mode to try to get the best mpg possible.

It is winter with winter gas, I keep warm-ups at a minimum 2 minutes max. drive 70% city traffic and 30% highway.

For an unknown reason, I cannot for the life of me get any better than 11-12 mpg !!!!

I insist on being extra careful to yield the best mpg possible. Reading about guys on here with 3 inch lift and 35s getting 16-18 mpg gives me nausea !!!

Makes me feel like the brakes are stuck on, or I'm pulling a parachute or something.

I didn't buy a Jeep for the fuel economy, but was suppose to get at least 15-17mpg.... In fact, my brother with a 2013 sahara, 3.73 gears, Teraflex budget boost and 33 inch Duratracs is getting the figures I was expecting.

Have they found anything wrong with some jeeps that would explain what is happening to me ????

I did notice when my brother and I were at the dealer, getting our tires installed, I spun my rear right wheel while the Jeep was jacked up and I could hear a constant clicking, while my brothers Sahara didn't make that noise. I figured it must be the lockers and didn't bother asking questions.

Please help me correct this.

thanks!

Are you gojng off the VIC on the dash or hand calculating it? Your onboard computer may be lieing to you.

Both, I found that if I reset the evic when I fuel-up, the numbers match my hand calculation for that tank. Then I fill-up, reset again and ..... I normally would not insist on making mpg better, but these numbers are ridiculous.... If I had 4 inches of lift and 37 inch tires on stock gearing maybe, but with my current set-up, it's un-acceptable !!!

Kinda hoping someone's been there, they found something and you know....

^^^agree with the above. The computer may be off. Assuming you have accurately hand calculated it, that is definitely way low. You should at least be in the 17-18 range.

I've never heard a clicking, but doesn't mean that it isn't normal.

my stock 13" JKUR with 3.73 gears gets 14.5 MPG
my buddys stock 12" JKU Sahara with 3.21" gears gets 21...
not happy either, but what can you do...

Da10A

I know, I know, that's why I'm banging my head on the walls trying to figure it out.


At least you're getting 14.5 !!!! If I was getting that, I never would have started this thread.

I have a 2013 JKUR stock right now. Just around town millage is 12 to 13 and with commute to and from work witch is 17 miles each way but max speed is 45 I get a combined 18 mpg That's hand calculation. Not the Jeep computer Best freeway only milage has been 24 mpg

My JKU with 275/70R18 (33x11), Auto, 3.73, & Procal is getting 11mpg in town right now on winter gas. Yes, it sucks. Summer gas I get about 13/14mpg in town and 19mpg on the highway.

Granted I have a 2 dr 2011 with 3.73 gears, 255's at 37, heavy bumper and winch with automatic. I'm getting around 15-16. With higher rate of coils, spacer kit and no lower front air dam. It does vary because I can be hard on the pedal. The mpg gauge in my opinion blows. I clear out my mileage gauge everytime I fill up.
