You're barking up the wrong tree if you're looking for a lifted jeep and concerned about mileage. There is no single answer.
Differences would depend on the engine, trans, axle ratios, lift height, tire size, etc etc etc. Too many variables.
I have a manual trans 2012 rubicon with 4.10 gears. Stock it got around 19mpg highway if driven easy. Now with a 3.5" lift, 35s, bumper, winch, heavy/taller top, I get around 17mpg in similar conditions. 16 in town normally. As low as 13mpg high in the winter if the roads are covered in water, it's windy and I'm driving 80mph.

So my guess is you'll lose somewhere between 1 and 8mpg. Useless right? The answer is it depends, and if you're concerned, don't lift it. Or don't get a jeep in the first place.

I would say that lifting itself is negligible at best, however removing the front air dam has been noted to have an effect. More considerable is the addition of big tires and increased weight.

Frankly, IMHO, if people are concerned in any fashion about gas mileage and fuel economy, they shouldn't purchase a solid-axle, 4x4 vehicle. A proper decision-making tree would include: choosing form and function, overall cost of purchase, cost of operation and maintenance (including fuel), etc. before deciding to buy. But that's just me. And that's why I don't drive a Corolla.

Corolla? A SmartCar seems better for you.....
Agree, too many variables just in general about anything you do to modify your Jeep from factory will result in lower mpg IMO, just how much depends on all those other things (variables)...

Any extra weight decreasing your mpg, lift is normally done to install larger and heavier tires and tons of other heavy cra. on your Jeep Wrangler is initially bad aerodynamically, lift is making it worse I believe.
But you are getting great look and improve your off road abilities, so think about what is better for you? I am not lifting ...

Went from 19-20 mpg highway to 16-17 mpg after adding 3" BDS lift and 35's. Didn't buy if for fuel economy, so it didn't matter to me.

3.5" AEV lift, 37" KM2s and I get 14-15 MPG around town.

I didn't buy or lift for economy. But my 2008 JKUR with a 2.5" rock krawler lift and 35's and 5.13's got 19mpg on a recent trip upstate, and 17 on the way down towing a 1500lb trailer. Gas mileage is directly proportionate to how hard you press on the skinny pedal. keep your cruise set at a respectable number(sub 70mph) and it'll do ok.

Lifting doesn't impact mileage in and of itself. The extra weight is usually negligible on most suspension kits, but wider/taller tires or aggressive treads with greater rolling resistence will adversely impact your mpgs.

I get about 15 mpg with 35s and 3.73 gearing [2008 JKU]. The newer generation engine 2012+ may yield a little better.

I'd have to agree that the lift alone won't effect fuel economy. A jeep is about as aerodynamic as a dehumidifier. Kind of hard to make it much worse. But almost no one lifts without putting on big tires, and the tires are what probably kill your mileage.

Probably not applicable, but I lifted the front of my 11 Ram Hemi 2.5". (Stock tires) At the same time, I installed an AirRaid cai. I think I actually picked up about 3/4 of an mpg; which isn't much, but better than a loss. From Cullman Al to Jasper in, I got 20.7 mpg, hand calculated. Not bad for a vehicle rated at 19 mpg.

MPGs are the reason I'd want a diesel.

Holly molly !!!! I just asked a general question & you guys brought me down to the "corolla level " . Looks like i touched a sensitive nerve .
I want to enjoy the perks of a lifted jeep but also was thinking of my daily commute . Was trying to get the best of the two worlds .
But I liked Hub0619's answer the best ......Thanks
FYI : My other car is Benz S500 ......an 8 cylinder monster ........i'm not the corolla type of a guy ;-)

Sorry Bud, but this happens from time to time when lift and MPG appear in the same post.
