2013 JKU
Automatic
Re geared to 4.10 Truetracs added front and back
Mainly country driving
Averaging 12L/100kms running ethanol free gasoline. (Last tank was 11.7)
I've currently got the stock wheels and tires back on. I noticed tire size/weight affected my mileage far more than the gear ratio did.

 

ouch..Iam around 15 to 16 L/100km

 

50/50 highway/city
Stock JKU w Steel front and rear bumpers

10.6-10.8 L/100km
Mostly highway @ 90-95 kph.
2014 JK Sport B auto with 3.73 gears and factory 32" wheels

 

WOW - Woodsman u running down hill in mexican overdrive all the time to make that kind of mileage? Never heard anything near that b/4 even at those speeds. How did u come to those figures?

 

Off the dash.
What I pay at the pumps seams to be around the same range.
BTW: I learned to forget the heavy foot when getting up to speed.
Also use the cruise control.
And by highway I mean paved country back roads with little traffic and only a few stop signs.
Aprox. 50 km's each way to work & back per day.
On the 400 series hwy's or QEW speeds would be much faster & mileage much lower.

 

I actually saw pretty bad milage when I first got my truck, but once I hit 16,000kms it actually got alot better. Used to get around 13L/100km 90% highway at first.

I do short 10km commutes now all city driving.

11.5L/100km
100% city
3.73 gears, stock 255/75R17 wheels

I notice huge leaps in the usage upto around 12 if I shift higher then 2000rpm, I've yet to do extensive testing on the highway. But from of the short 60 - 100km runs I've done I have hit around 10.8L/100km. I think also a major factor, 2 doors will use less fuel then 4 doors.

 

mine is the 2015 wrangler sport 343 km sort of new ...milleage shows 11.0 to 10.8
on the dash

 

As my mileage has gone up my fuel consumption has got a little better.
For my runs from Seaforth to Stratford I'm averaging 10 L/100 Km or slightly better.
