Unlimited rubicon: 27mpg+ city average
 
I was out driving this morning in city traffic and didnt notice I reset my mpg gauge. I looked down and it was reading 29.3 mpg and I thought wtf so I carried on for another 5 mins and it was still over 27mpg even between red lights. So I made a 6 min video of it averaging between 27-29 mpg. Shifting 1st to 3rd to 5th then 6th seemed to help keep it up and staying right at 50mph was the sweet spot. Normally I drive in a hurry everywhere I go and never get less than 18mpg in any case but I do baby the truck.

I posted this because I've noticed a lot of guys saying they can hardly get 15-16mpg so maybe this is some hope for y'all. I can say for sure that when I drive the truck more patiently my mpg goes up alot from that normal 18mpg but when i really try that 27mpg+ isnt that hard to achieve. If anyone wants to see the video ill post it up.

That's interesting stuff... I guess first thing first: Are you tires stock size?

Post it.

The computer isn't a very good measure of true gas mileage especially if it has been reset anytime soon.

Very true. When i reset mine in my 2006 GTO i was on the highway headed to Daytona and all of a sudden went from 17mpg to an amazing 32mpg.

There's no way, I'd be willing to bet your computer FUBAR. Fill the tank up then reset trip ODO to see how many miles you get out of a single tank.

jadmt 05-17-2013 09:10 AM

i can make mine show all kinds of high numbers depending on how I drive etc but bottom line when I fill up with gas I divide the number of miles driven by the number of gallons taken and that gives me my real mpg regardless of what the computer says.

With a tornadic tailwind I was getting 27 mpg once on the display, which quickly plummeted around the bend and up the hill.;)
**Averaged off the fuel receipt, I get 20 mpg on a tank usually.

freedomrider 05-17-2013 11:16 AM

I am willing to bet my first born child that your computer is just showing false numbers. But that would be cool if it was true.

pepatrick 05-17-2013 11:20 AM

I get 27mpg and I paid 20% below invoice for my 2013 JKU Sahara...NOT!!!

20mpg is not bad at all. I would take that!

06 Red Rubicon 05-17-2013 11:28 AM

The truck is a bone stock 13 manual 32" bfg's

With my typical driving being in a rush but still at 18-20mpg I reset the trip a and b at different times to record tanks and most my tanks show 360-400 filling up with around 2 gallons left so the computer is not far off at all(22.5 tank). Then again it would be higher on average if not for occasional bumper to bumper traffic. Since I cant always have the same conditions as I had today it would be hard to record a tank after it reading 27mpg because I just simply dont have time to lolygander on the road like this morning haha.

I know the computers are not very accurate immediately after reset which is why i waited more than 5 mins to let the computer settle then recorded. I will post it up later today when I get back to wifi because my iphone POS 4 takes years to load a 6:39 video.

There are a lot of variables that contribute to getting high mileage such as,

tire pressure
coasting to lights and corners at the right time
skipping gears
take off
acceleration
driving arrow straight
not filling up with shitty gas
average speed

I notice on the highway it struggles to get that claimed 21mpg if I run more than 65mph. But under 55mph the mileage goes up a ton, due to gears of course. But also lower speeds help its brick in the wind aerodynamics not effect mileage as much

Ptrowski 05-17-2013 11:30 AM

I am averaging 17.4 MPG on my 2dr Rubicon, so I highly doubt 29 MPG.

I have gotten 29 on multiple occasions coasting down hill with a 50mph tail wind too. I also get between 18 and 20 highway when I'm nice to it.

Sgt93 05-17-2013 12:21 PM

I'm still laughing reading this :rofl:

Blastek 05-17-2013 12:31 PM

you can get 50 mpg in a jeep if it's all downhill. If you want it to be more accurate, you need to reset the computer while your foot is in it (around 10mpg) and then drive normally. If you reset it while coasting, the average of 70+ completely offsets reality and it takes a very long time to adjust itself.

My morning commute is 26 miles. If I reset it on the highway 1 mile from my house, the computer reads 27-28 mpg by the time i get to work 30 minutes later (no traffic). But, if I tank up and hand calculate, it's really only 22-23.

BManz 05-17-2013 12:41 PM

A guy I know bought a 2012 Hyundai Elanyra and bragged he "averages" 45mpg. Horse hockey! He resets his computer on the highway and sure enough it's 40+mpg for a short while. BUT, but -- when I watch him fill it and do the math he averages barely 30mpg overall per tank mixed driving. I wouldn't drive that POS given the small diff from my JK.

My 2012 JK auto with stock size Duratracs and 3.21 gears averages 20-21mpg per tank mixed driving on summer gas with 24+ regularly when 90% highway. The EVIC matches the pump math. I do drive like an old man most of the time though.

Now, if I reset the EVIC when running down the highway at 50mph I can see it indicate 40+mpg too----in the short run. Heck in the short run coasting down a hill at 45mph even the brick Wrangler averages over 200mpg for that 30 second coasting run, lol.

The EVIC is accurate when used correctly.

06 Red Rubicon 05-17-2013 01:49 PM

My highest ever that I was paying attention to, was a 464 mile tank filling up with 2.5 gallons left meaning i used about 20 gallons. The gauge read 24avg when I filled up but the first 1/8 of the tank I was towing a 4Runner on a dolly. The rest of the tank I was trying to squeeze every bit out of it. Calculated I got 23.2 mpg but wonder what it could of been without all that weight behind me.

While god forbid it could be wrong haha, I did average 27 for more than 15 mins, then after shutting it off and getting on the road it read 25.6 for another 15mins until I needed to haul ass to make an on ramp. I will say, it reads really high until I need to get on it but if im careful it does stay high and the pump proves it.

BTW: I usually average 16.9mpg towing 4runners behind me, the lighter 2 door would get around 16.8mpg. Lower due to the auto trans, shorter wheelbase and tendency to sway.

Point is, if you haul ass everywhere like I do you can still average 18-19mpg, but driving the truck just right makes a MAJOR difference in mileage.

madeinhb 05-17-2013 03:02 PM

There is no way. You keep stating how many miles left, blah blah blah.

It's simple. Full tank up, reset trip meter, when you fill up next- take the miles from trip meter and divide by how many gallons the gas pump said you put in. That's the true milage. The computer isn't true at all.

chrisfp88 05-17-2013 03:34 PM

The computer is crazy. When mine was stock I was coasting down a steep hill no accelerator no brake and I had hit reset. The evic said 452mpg. Lol.

Old Dogger 05-17-2013 04:30 PM

My 2013 JKR gets about 16 in town and 19.5 on highway.

Jeeps_and_Boats 05-17-2013 04:40 PM

Its mildly entertaining to watch the numbers. I was able to push a JKU to 18 this morning in traffic. Didn't stay too long.

Not to be mean but if you READ you can see where I posted miles to the tank and calculated ACTUAL mpg. Also stated how I don't have the time to putt around for a whole tank so it would be hard to test it out.

Of course the gauge is off somewhat from actual, however after a few mins it settles and is pretty close to the actual which I've found from testing.

A few minutes is nothing. Give it a few days and then post again.

06 Red Rubicon 05-17-2013 08:23 PM

Again, If only I had time to putt around like today and do that I sure would like to see what's the most I can get for fun. ATM it's at 22.3 driving normal

pepatrick 05-17-2013 09:08 PM

It's the new Jeep Priusicon

Pennsyman 05-17-2013 09:41 PM

Sounds hokey....my computer said 18.4 the other day....and I was happy! Doing the tank math, its around 17 or 18 consistently.....we all know the truth here folks.....gas mileage ain't the reason we bought 'em.

06 Red Rubicon 05-17-2013 11:50 PM

Well what the fuck I bought 3 rubicons because I was told they got better gas mileage, I think I've been scammed. What they didn't tell me tho was how nasty of a 2nd gear scratch I could get or how easily it could beat a hemi ram or 4.6 GT

dreinecke 05-17-2013 11:59 PM

My '12 JKU gets 21.3 average from Monument to Denver, CO over 500 miles every week. The computer thinks it is about 21.6. I use the manual calculations. I have a 6-speed, 3:73 LDS and an AEV 2.5 DualSport with 285 Duratracs. The key to my driving is that it is 90% highway at 70-75 with little stopping in traffic. Going out to Missouri and only stopping for gas I averaged 23. The other key to my mileage is how I drive it. If I take it easy, I can get the same average every week. Drive like I stole it and it dives to 16MPG.

WranglerKCCO 05-18-2013 01:21 AM

I have a 2012 JKU sport and what I love about it is that no matter how I drive it I get around 18-20 MPG
