Yeah right! So I have a 2001 AW4 stock and the last few tanks have been getting worse....12mpg....11mpg and the last tank I got 10!! Thats right, I got a whopping 154 miles on my tank. No CEL so I figured it is an O2 sensor. Bought myself a ScanGaugeII but turns out it doesn't have sensor functions but I thought I would monitor what if gave for instant mpg. On my way to my inlaws tonight, 60mph on the highway and it was bouncing from 28-31mpg!! Yeah......I don't think so! Weird thing is the rpm, speed and temp was showing accurate. Guess I'm gonna try and sell it on CL and buy something a bit better.

 

I'm on the app so I can't see where you're from, but if you start your jeep in the morning to warm up, you're technically getting 0 miles to the gallon. During winter I don't expect miracles from my efficiency, but I do expect it to perform in any condition. If you're looking for something that gets good gas mileage, an XJ isn't for you :/

 

Lolz. The last time my overhead console read 30mpg I was coasting in 4wd full time. Obviously not an accurate reading.

Stock Cherokee is probably getting 16-20 mpg.

 

The mpg is bad in the morning, better when I warm it up but 10-12mpg on a stock XJ! Come on really?! I would get that or a little better in a full size V8 truck. I don't expect mid 20's but 14-15 isn't unreasonable on a stock XJ.

 

I get 14-15 on my 33's!

 

I get 13ish on 4.88s. Stock I was getting almost 25.

 

Join the club. 8 with 31s.

 

Full time 4wd only uses 0.03 mpg more on average per trip.

 

I had little 235's, with a set of axles, long arms, my life... And got 17mpg.

But my bumps had rotted off and i hit a bump which bottomed out my shocks ending in my pass. side shock mount cracking off of the axle.
I got good gas millage my entire 1000 mile trip, just didn't have a shock for half of it.(i have bumps now)
Maybe it's my young engine, 125,xxx

Well anyway good luck on the search for mpg's

 

YES! Another fuel milage thread...

 

For real!

 

Sorry, it was more meant for the inaccurate reading of the ScangaugeII I purchased, not so much for mpgs

 

You do whatever you want bro... Lol...

 

Got to admit, I've got the 2.5 diesel and I get 31 on a run, 25 average, but I do half pint to the mile..

 

I'm averaging 17mpgs in stock form.. idk how 10 is possible
