Oh well. She is good to me, otherwise.

I have a Fuel's Log with Excel then I keep all the informations (Date, City, Odometer reading, #Miles, #Gal, $/Gal, Total $, MPG, etc). The 21.77 is the average from the first day, included windy day, traffic, cold and hot weather, highways, gravel roads.
The size of the tires makes a big difference too.

CJS98TJ I get 180 to a full tank 4cyl and 33in toyos roughly 10 a lil more all depends on how I drive it.

Hellbilly In my 2010 I am getting 15 mpg/city 20mpg/hiway. 255/75r 17, don't know the inches, 32's I think. The mileage all depends on the weather also and how I drive it. I really did not by my Jeep for it's mpg's, but for the confidence and fun it provides.

Jon M I have a recently purchased 02,5spd 6 cyl. had 30- 9.5 - 15. Was getting pretty good milage, topping out at about 19mpg w/ cruise and the relatively flat FL highways. Haven't done a full check with the 31 dura tracs, but I'm suspecting similar results.

98-4Banger ive been driving a 08 nitro with dash computer, whihc tell mpg, but something you guys must now unless u dont already is, tht its an average estimate, try reseting it when you leave for work or what not and checking, because if you dont it will show you the average of all the driving in the past 60 miles, usualy.. so i mean, you drive highway and get 18mpg, then do a bit of city, so down to 10mpg, then back home using highway, then a bit of city, and all that is mixed up into one reading.. thats how my dash computer works, im not sure botu jeep cause i got a 98 tj

apantages I've had my JK for two weeks and feel like I am always at the gas station. I get about 17.5 miles per gallon from a full tank. Haven't done any upgrades yet.

RubiRush We have a 2010 Rubicon 6spd and we average about 16.8 mpg doing about 70% city and 30% highway. Usually on the highway I'm running 75 or better.

From what I'm reading here and on other boards that's about average. I've seen some doing better and some doing worse but the majority seem to be where we are.

On a recent trip of 120 miles on mixed use roads, which is 2 and 4 lane roads non interstate, I averaged 17mpg with an average speed of 63 mph.

JeeperJake Don't know if this is the same basic software as my Dodge Ram, the hardware setup, display and knob in seems pretty similar and MB was part of the Company when this stuff was first installed in retail models.

Read your owners manual to see for sure...mine has 2 different averages; display is cumulative since last reset; push the knob twice and it resets so it reads for *now*.

I drove the 08 last week on a 20+ mile test loop. We started at "10.3 mpg" which freaked out the salesman. We drove enough so after I reset it a few times & got about 10 miles away from the lot, it was working its way up toward 20 mpg, and finally stabilized at 22.0 by the time we got back to the lot.

Whether that's meaningful or not I don't know, but it was the same kind of operator input as what the Ram uses.

And I could live with 22 mpg if my Jeep really were getting that.

rogertc1 Heck my 1995 YJ 4 Banger gets 24MPG average.

I hope so , because 10 mpg is horrible.
10-02-2010 06:46 AM
X... Now is that dash comp is averaging the last how many miles/klicks? When doing a _lot_ of highway driving I do see it drop into 10.X litres/100 kilometers. But this thing is pretty new still, so who knows.

dfwislander I went from about 18 down to 14 in my 2002 after 4" lift and 33's. Then regeared, back up to about 16. I'm seeing 17-18 in my new one stock

On the highway I have to floor it to get to 68 mph and if you let up a little it just wants to slow down instantly. When I can afford it I will upgrade the aircleaner,microchip and the exhaust system. I hope that will improve performance and possibly even improve mpg to the 18-20 range.

Something must be wrong with your Jeep then because I am running 33's with lift, aftermarket bumper, winch, and steelies, and I can easily get my jeep up to 85 without kicking it outta overdrive.

haleycbrrr buy some 4 hole fuel injectors...and get rid of the restrictive airbox...the key to the best gas mileage you can get is to get the motor running as efficiently as possible, cause you can't really do much for drag, so you must improve performance. the less hard the motor has to work the less gas its gonna consume. but its not gonna be dramatic, thats for sure. I like to think of my jeep as my metal beast that when i feed her gas, she takes me on fun adventures

ncossey I think the multiplier effect has caught up with me on my miles, today when I made my trip to school and back, I calculated the total miles driven, and compared that to what was on my odometer, off by almost 40 miles, So after I added that in with my 202 miles to 3/4 of a tank, refilled using 14 gallons, came out to around 17 AVG mpg, which isn't anything to complain about. Having speedo recal'd on monday just to make sure.

Either your math is wrong, or somethings up with your Jeep.
Same here. Got a rubi unlimited running the stock wheels still and at about 15.9mpg (hard top as well)

glogsdon1 I have a stock 2010 Unlimited Mountain Edition, so it has 255x75x17s and a 3:73 rearend. It has an auto. trans. with about 1100 miles on it so far. I am getting 18-19 in town and 20-21 on the highway running 75 MPH. That is better than my former 4.0L, 5 speed '99 TJ. I am satisfied with the mileage.

snopro269 I have a stock 2010 rubicon 2door and I drive it like a drunk golfer in a golf cart and I get 15mpg in town and if I drive it on hwy at 67-70mph over a 300 mile trip I get around 19mpg. I calculate via old school way and not the fancy thing on the dash. That thing tells me I get 17 in town and 22 on freeway!! I wish!! BTW I have an Auto Tranny as well!!!
10-01-2010 05:35 PM
popstop785 With city driving, I get between 13-15 depending on the level of the ground. Highway I get between 17-20. There is a stretch of freeway that has a steady decline for miles and my dash showed up at one point for 25MPG at 70MPH. I usually get near 300miles per tank... not great but I have never owned a vehicle that got anything great so I am used to a gas hog.

Oh and I crank the a/c and have only added 33 tires, otherwise it is stock.
