Im sure you didnt buy a jeep for fuel economy .lol its like pushing a Mac truck down the road. We buy jeeps to play in the mud and have fun.

You made me check the 2011 specs...the 2-Doors have a 70L and the Unlimiteds have 85L tank

Hmmm

Re: Gas Mileage
 

If you want to save some gas, get yourself a set of 5 tires and rims. The tires should be thinner and made of a hard rubber compound. Right now your tire is a LT255/75R17 and gets 661revs/mile so you just have to find a tire that gets close to that. A tire calulator will help.
And you'll just have to swap them on friday after work to go play :)
Don't forget to wave!

Re: Gas Mileage
 

It takes about 3000 k for the trans computer to adapt, but I never noticed a difference in mileage. I get 10-11l/100 km if I drive with eco on, at speed limit, no passing, from Ft. Mcmurray to Kamloops. With my current 4.10's I get no better than 14l/100 km from kamloops to Hope. Around town, I have no idea, I've yet to go a full tank without hitting the trails. 4 low burns lots of gas. I saw it at 22/100 km once, after filling up, resetting the comp and hitting the road. Weird, because it only took 3 hours to go 6 km.
So 9 to 22 mpg is average

Re: Gas Mileage
 

Sorry Friend but it doesn't take 3000km. The TCM witch is part of the PCM learns shift point with in a few km. And continues to adapt all the time for the life of the transmission.

Re: Gas Mileage
 

Well,i'm going to call the dealership to see if they can Flash the computer to reset it.

after 15000 km's, i avereage out at 14L / 100 km's and 13000 Km's is all highway driving between 90 and 100 km/h

The best being at 12.7 l/100km one tank only.

will keep you posted

Re: Gas Mileage
 

Damit mine suck now. Stupid lift. 15l per 100kms

Re: Gas Mileage
 

Really anybody that says gas mileage and Jeep in the same sentence, shouldn't own one. Lets see...Shaped likea brick then we lift then...install bigger tires and Guess what - the gas mileage sucks. I have driven Jeeps since I was 16 and one thing that is same in all of them the gas mileage isn't great...... You buy a Jeep for what it is a vehicle that will take you anywhere. You want great mileage buy a Jetta diesel.

Re: Gas Mileage
 

I'm running a stock '10 JK Sahara 4door manual trans. When I first bought it I was running about 19.5L/100km. A short time ago I changed my driving style (read: I stopped driving it like a sport car) and went from regular gas to premium. Now I try and keep my RPMs to no more than 1500. I'm on my 3rd tank of premium (not super, I'm not that rich ;) ) and the average mileage is ready 17.0L/100km as of this morning. I have almost 7000km on my jeep. This is all in town driving so I never really get above 80-90kph. If I can get it down by 1-2L/100km more I'll be happy.

I hope that this helps you out.

Re: Gas Mileage
 

I drive 130 km per day with my 2011 Sahara Unlimited, 6 speed manual.
(30 minutes in town, 1.5 hours highway)

I am averaging 11.5 L/100km according to the dash. Driving 85-100km/h mixed highway. (Highway 7 Near Peterborough)
When I reset it on the highway, I get 8.5L/100km while driving at 85km/h (but its the small towns it goes up to 10.5>11.5)

We try to keep it in 5th in town, and 6th on the highway.
