Last tank in my Ram I got 7 mpg.

Quit whining.

In my V8 WJ I averaged 16mpg, and on long freeway trips I was able to get 22mpg cruising at 60mph. K&N and Flowmaster for mods.

I'm getting around 15 mpg for normal city driving. Mostly in town with some highway.
I have a 2002 Wrangler Sport, stock with Bigfoot XT 31X10.5 tires, five speed.

I can get between 19 and 20 in the city and only 15 on the hiway with an automatic with no overdrive. I have 33 inch tire and stock 3.55 gears. What helps me the most was changing to mobil 1 oil, custom exuast, and a open air intake. One thing that seems to work realy well on my 98 tj is to regularly clean the throtle body and keep up on the cap, rotor, and plugs.

hrmm this raises the interesting question.. most stock YJ's get between 19-21 mpg w/ the 4.0.. least mine does..so here's the question: WTF did Mopar do to the TJ drivetrain/engine setup to screw up the mileage so bad? were they just thinking of following the leader with the other big *** suvs.. since they get crappy mileage the wrangler must too??

I think it may be a stock/non srtock thing here.

My stock 2001 30" tire dana 44 soft top 4.0 sport gets about 18-20 around town and 20-22 on the hwy. I'm pretty religious about figuring the milage and I have the 5 speed and drive pretty conservatively...

You can accuse me of flying the BS flag, but I really went out in the rain to get my book from the glovebox...honest...

For the first 3K miles, I averaged 17.3 MPG. After changing the oil and switching to Mobil 1 synthetic, I was running at 18.4 MPG. I'm still in the last stages of the break-in period.
Don't know what to expect down the road.

Beats the hell out of me? I have had the 'ol Jeeper for 3 months, and the first highway trip from Texas to Oregon I was getting 20-22.

That was back in early October. Well, for November, around town in Oregon I been getting 14.5 like religion!? (I calculate my gas milage at the end of the month for the month...October was great, November has sucked!?)

I just got a K&N and switched to Castrol Syntec, so we'll see.

Maybe it's the "winter" formula gas?

And that is a good question, why do YJ's get 20mpg? (I don't even have a distributer and rotor to clean, go figure...)

That is why I though out the B.S. flag. I don't know anyone that really gets better than 15. My division must be different than everyone else's or their calculaters are screwed up. I might get 15 on a good day.

I'm glad to see I'm not the only one in the 15 mpg range. Just put on a K&N and haven’t burned out a tank yet to check for improvement. I put up another post a few days ago trying to get feedback on the throttle body spacers and who liked them. Like the other post said about his Dodge Ram. Try my 86 F250 4x4, 460 with 305x16's….a good day is 6 mpg! I love that Jeep mileage!!

I often get much better than 17 MPG---when I'm towing my TJ with another vehicle.

Sorry dude, but your BS flag just got run over into the mud. I've been getting 19-21 mpg CONSISTENTLY for the past 8 months in my stock 4.0L with manual transmission.

In the very same vehicle, I used to get a consistent 16-17 mpg when I lived in Atlanta, Georgia. But when I moved across the country to Santa Fe, New Mexico, I instantly got a 3.5 mpg increase!

Biggest secret, 45-60 mph seems to be the range for getting the better MPG in my TJ. At speeds of 65-80, like I often drove in Atlanta, the Jeep's flying brick wall aerodynamics severely kills your fuel efficiency.

Also, realize that gasoline mixes vary across the country due to altitude and local anti-pollution requirements. So fuels sold in bigger cities where pollution is an issue are often less polluting, but also less efficient.

7,000 ft. altitude also hurts the power a little.

I'm in Santa Fe. Are you a member of the NMVJC? If not, you may want to check it out. We have a lot of fun with runs almost every weekend and sometimes both Sat. and Sun. Send me a PM if you're interested in going on a run.

I get a big grin when I get over 13 mpg. I haven't had a big grin from getting over 13 mpg in a long time now.

I have checked my mileage twice since I bought it 2 1/2 months ago. I get 18mpg with mostly Hwy driving. I have an auto with 31's and 3.07's. I just did a tune up this past weekend and am waiting to find out if it helped the mileage.
