2013 2dr Sport S 6sp manual with 3.73's and 2,500 on the odometer. My mods are rubicon rails and ace rock rails (unless you want to count plasti dipped wheels and quadratec grab handles)...my last tank of gas with mostly highway miles calculated by hand was 22.6 mpg (evic readout said 22.6) I will probably wind up filling up tonight or tomorrow and will be able to tell you the mpg's from this road trip. Right now the evic readout says 22.9. We'll see.

I live at 7600 ft too, and usually average around 20 mixed driving. On a recent round trip from Tao, NM to Salt Lake City, via Moab I averaged 21.0 for the trip. That included driving out to a Canyonlands overlook, and a day of visiting Arches NP. I have a stock '12 JKR with 4.1. Must be the Arnch paint.

^^ on my list for next year once a few more mods are on.

Any suggestions for trails up near Taos? I have not been up there for 10 years or so. Sandia Ranger District closed off a lot near Abq.

Was just remarking that the Jeep gets pretty good MPG

2012 3.6 stock tires - 3.73 rear

Usually 20.5 or higher Highway (trip to Cincinnati 21)
Trips to Daughters college (20 Mountains)

Around town and work 16.5 and higher

BTW 21,000 and no TICK

My 2012 stock with 32 KMs- all the time, and more at 55-60. It's a different story now with 35s and with the front up of the Jeep higher than the back. I even preferred the rake over this reverse rake, but that's a different story. I regularly got 20-21 at 70-75 MPH. At 50-60, it was 22-23.

Here's a good reason to do the math yourself. I'm not quite getting 336.4mpg. Seen it as I was going down hill and tried to shoot it with my iphone, kinda blurry. I have a 2011 JKUR auto w/35's / 538's / 3" lift / and extra weight. Bumper, winch. It gets 16-18

MPG Numbers...

I'm just throwing this out there because I haven't seen anyone mention it. I believe that the Highway mileage numbers are based upon 55 mph. Sure, I realize that more often than not, many of our highways are 60, 65, or even 70 mph. However, the numbers are still based upon 55 mph. I have 3.73 with a 6 speed, and stock 32" rubber. I'm currently averaging 20.5 actual (not Jeep computer) mpg. This includes trips to work (10 miles), some city, back roads (45 mph and 55 mph), and some highway (65 mph). To get this type of average I absolutely have to drive conservatively. Hey, it's a Jeep, not a Corvette. I don't feel the need to drive it like I stole it

I get better mileage in the city than the highway. Wind resistance is a bear. I average about 17.5mpg around town but drop about a full mpg on the interstate at 70 mph.

2013 Sport 2 door, 6 speed, stock with 16's and 3.21 gears. Best I ever got was 22.3 from Richmond to Philly, and that was with hitting DC traffic. I do drive like a little old man though. I average 20.3 daily driving. The numbers are from an MPG app. but the Jeep display is pretty close.

I have no problem getting a steady 18.5 combined and I commute from 8400 feet to 5400 feet. I really try to go light on acceleration starting from a stop and going up hills and manage my downhill for maximum mpg. If I just drove hard I would lose 2 mpg very easily. I recently completed a long road trip on interstate most of the way at 75 steady and ran from a low of 17 to a high of 18.1 on both legs. This is with all mods lift ect. I did not drive it long enough in stock trim to get a feel but the first tank ran 19.2. And i run 3.73's w / Auto. trans.

'11 JK Sport S 3.73 automatic with synthetic lubricants in the engine, front and rear differentials.
For me the highway terrain and speed have the biggest impact on gas mileage.
If I keep the speed down to 55-60 mph and the terrain is fairly level; then I can see around (calculated) 21-22 mpg. As the speed increases or terrain changes; the gas mileage goes down.
On a recent trip from Escondido to Costa Mesa driving 65-75 mph I calculated 20-21 mpg going both directions.
Generally city/hwy averages are 16.5-17.5 mpg.

My absolute best was 20mpg. Around 300 miles, 250 of which were highway going 50-55, a big Jeep convoy, and the remaining 50 was trail riding and putting around town.

Last highway trip, again about 300 miles ALL highway going 65-75 with myself and 2 passenger averaged 18.

make sure your tires are inflated properly...use cruise as much as possible on highway (except in hilly areas)..and try to keep it under 70... believe me I KNOW its hard in Jersey....

How close are the 2012+ mpg on dash vs actual mpg? I've never had a vehicle dash that didn't inflate by 1.5-2 mpg. 17 on dash is about 15.75 actual on my 2010.

I can easily get 20.5 to 21 on the highway in my stock 2013 JKUR as long as I keep the speed around 60-65 MPH and use cruise. With the shape of the JK it is all about wind resistance so keeping the speed down is crucial. I also only buy ethanol free gas which I think makes a difference of about 5%.

I made the trip from Chicago to St. Louis a few weeks ago was getting 22 MPG (no proof, sorry). Had the cruise control set to around 70-75 and just stayed in the right lane down I-55 for 5 hours.

Just filled up for the 4th time since keeping track.. mostly in town driving and a stellar 12mpg! If I want to go on any road trips, I might as well take my motorhome and tow the jeep.

someone else said it, you should be measuring smiles per gallon, not miles.

2013 JKUR i probably get 16mpg and its almost all city. if i do any horsing around its more like 15mpg. i track with EVIC and app, they usually are very similar.

2012 JKU 3.73's and I was getting 21-22 on a regular basis while traveling on the Thruway at 65. That was before the lift, bumper, and winch. Not getting that now.

Those of you with pentastars and want better mpg... Try going light on the throttle for a day. You'll know you're doing it correctly when every_single_vehicle around you leaves you behind from a red light. You can then catch up once you're around cruising speed. Also, when speeding up while already at cruising speed, try to do it lightly enough to where the ECO light never turns off. It's a nice little challenge.

I think these must be big reasons I'm over 20mpg in a JKU and my wide over 21mpg in a JK

Ditto. I'm now averaging 20mpg per tank on my stock 3.21 geared JK and on strictly highway I'm calculating a better-than-EVIC 24+mpg so long as I keep it at/under 65 in non-windy conditions. Driving habits are the biggest factor.
