Curious to know all your fuel efficiency

[longlivenintendo]

I've been super stoked lately because with the recent fixes I've done, fuel injectors, spark plugs, air filter, new exhaust my 08' is running at 19.2 mpg. I'm curious to know what you all run at? I'm all about efficiency. I'm curious if she ll go any higher. It could be also the new wax I put on her the other day too

14 / 16 MPG's on average. 17 on highway w cruise. 2013 JKU w 3.73's on 35's, auto w 3 inch lift. Calibrated speedo via AEV Flash Module.

14-16 on the road, daily stuff. On the highway I can get around 19 with the cruise control as long as I don't exceed 70. The minute I start going 75, it drops pretty significantly.
2014 Sahara, auto trans w/3.73 gears, 35" tires on a 2.5" lift.

2008 DD will see around 16-16.5, one time I saw 18 and that was a mixed DD/Highway trip with cruise control on.

Manual trans lots of Performance goodies, stock tires and 3.26 gears.

Update from a trip I did today to a 4x4 shop for an alignment. All hilly highway, mostly 65 to 75 MPH. I was actually under 17mpg. But that's fine by me. Im lifted pretty high w aftermarket bumpers and a 73lb winch.

07 rubicon. All stock except exhaust. 4:10 gears. Hills everywhere here lol stay around 16 DD. Highway can get her to 18 to 19

Damn. My fuel economy is shit compared to y'all . 13.8 as of today.

Jeepers - '11 JKUR with a lot of mods. Stock 3.8L, 4-speed auto.12-13MPG average.
Thor - '13 JKUR with a lot of mods. 3.6L with CAI, Flowmaster Outlaw exhaust, 91 octane tune, M6. 16-18 MPG average
Loki - '99 Corvette with lots of mods. 800+ HP LS3 swap, M6. 32MPG if you drive like your Drivers Ed teacher told you to. Less if you drive like me.

All MPG figures are for Colorado driving. Altitude and terrain do impact these things.

12.5 on a good day. 3 in lift, steel bumpers, winch, roof rack, 2 baskets.

I do not care about fuel economy, I bought the JK for my country living, specifically our harsh Donner Party winters. All Good

Chiming back, even though there's people who get all 'bent' when Wrangler owners talk about MPG,

I do personally keep track of it on long trips. Why? Because even though its not meant for efficiency, I find it enjoyable when you can push the limits in fuel savings.

Today, on the way back from an upstate NY, NW NJ, 1 hour and a half drive @60/65mph, averaging 18 after getting off the hills:

@BigAL07, can you tell me what it is about this post that makes you sad? I'm honestly confused.

 

[BigAL07]

Just sad for your wallet at the gas station lol. Figured the 3.8 would do a little better than that. My billfold cries weekly

I think it does ok, for a heavy vehicle with the aerodynamics of a barn, a ton (literally) of heavy mods, driven in the mountains and rarely below 6000 feet.
Besides, I've always got the Vette for an economy car...

That’s because I don’t think actually do the math. The computer read outs are generally at least 1-2 mpg wrong!

I do the math when I fuel up. I never go by what the Jeep shows. My downfall is the short commute to and from work.

I probably have the lightest JK in the forum. 16in wheels no rear seat, no weighty mods. When I first took it for a 4 hour highway trip, not over 55mph ( that 6th gear stumbling under load) the silly thing on the dash told me I was getting 29 MPG at the end of my trip. But after 12 years of math I average about 18MPG. Almost no highway travel and a lot of fun in the snow now.

Most of my trips are 40-80 mile round trip. 65-70 mph 13–14 mph.

Check out where mine is at now! Boo yah!
