JT owners post your MPG

[robinja]

So I have ran through one whole tank of gas so far and I am getting 18.5MPG... this is 100% city driving.
Not bad so far, i think ill be able to get 19 - 20 once i get some more miles on it.

17.6 city - I've got a lead foot and could probably get 18 plus otherwise
23 plus highway

Still running stock wheels and tires on Overland Auto. Lift and new tires on order. Will update when installed.

I have a Sport S stock. I get about 17 around town. I managed almost 29 MPG driving 50MPH for several hundred miles, the optimal speed for best mpg. I should add I did this on on a national parkway with no stops exept to get off of the parkway to rest and get gas. The Natchez Parkway has only small hills along the way. The speed limit was 50

13.9 combined on the first tank on my rubi.

Still averaging 19.5-19.6 on my stock Sport S. No freeway driving at all, but some rural'ish back roads.

2020 Gladiator sport s with Max tow package, 4:10 gears. I'm running 315 70 17 BFG KO2S and 2.5" ReadyLift sst lift. I'm at 15.4 MPG after my first tank of gas based on the computer. Had the tires on since day 2 of ownership. Haven't reprogrammed the computer for the tires yet so based on the GPS app I downloaded I'm about 3mph off on the Speedo which will change that number once I recalibrate it. If I'm going 45 on Speedo I'm really going 48 which makes a difference in MPG. I'll report back once I get it recalibrated.

Just under 4 weeks of owning my JTR. AVG 16.8

 

[Jt-wrx]

Over 4000 km's on my truck (2500 miles)
2" mopar on 315 70r17's (35" x 11.5")
Sport S, 6-speed, 3.73
Speedo calibrated to gps at 80 mph, tazer jl mini setting required, 34.44"
Magnaflow street series exhaust, side exit

Last 4 tanks, winter driving, almost all city:

15.4 l/100 = 15.27 mpg
14.6 l/100 = 16.1 mpg (mixed with highway)
15.37 l/100 = 15.3 mpg
15.17 l/100 = 15.5 mpg

Average 15.1 l/100 = 15.5 mpg

I tend to drive left lane and push the pace.

On my way back from a trip to Virginia two hours one way and I'm averaging 17.9 mpg right now. It's fluctuating between 17.7 and 17.9 but it was up to 18.1 at one point. This is going through the foothills so a lot of up and down driving. That's just over 550 miles and no reset.

That's on 315 70 17 BFG ko2 Sport s with Max tow package. Speedo is also off by 2 to 3 mph

Be nice to see more hand calculated speedo corrected figures. One really has to read through the lines in this thread to find accurate data.

Since I put the bed rack on I'm down to 14.5 mpg. Mixed city highway. But that's the average for over the last 1k miles

On my jku after I corrected the speedo for the tires I ended up gaining a extra mile per gallon just for reference pretty much the same tires except I was running 35 x12.5 17 BFG ko2. Which were about 9 pounds heavier

Wasn’t saying the incorrect data was for or against better mileage...just that is inaccurate. Data is just better when it’s accurate.

That's because the computer now recognizes that you are moving about 10% further for each revolution of the axle/wheel.

Second fill up (around town) 13.9, Third fill up (all highway) 13.7... fourth fill up (same highway route back) 17.91. No idea whats going on there. I used 5th a lot more than 6th driving back. Not sure if the motor did some calibration during that drive or what but the mpgs seem to have jumped up. Stock 6mt Rubicon.
