Average MPG????? for real, not claimed...LOL

[SolidusJ]

All this junk I'm 5,1XX lbs going 14 MPG on the street and almost 16 MPG highway. I've been keeping a fuel log and 23 gallons on the street get's me 300 miles and 35X miles on the highway. :no: If you go with a 3 and or T stay away from the 3.7L, I baby her everywhere I go and keep an eye on the bullydog and miles at all time. Five years of ownership in a few weeks and I'm 50/50 on trading her in.

Gosh, I just can't resist this one. Current tank keeping it between 65-70 all but about 30 highway miles.

I'm hoping for better than 20 MPG. Hopefully in the future I can regear to improve it.

2006 H3, 35s, leveled, super skunk works engine swap.

How the crap are you all getting such good mileage?!

I have a 2008 3.7L and can only get 12 city (10-11 last month in the cold). Only things I've done are 305 tires and an ARB bumper (no winch yet). Highway, cruise control at 70 mph I can get about 18 mpg which isn't too bad. But still, I wish I got 15 city.

Get a PCM tune and a ported throttle body. Made a big difference in my rig

Bone stock wagon with 3.7/auto on 265 a/t without luggage rack and 15mpg average (well, 14.99) the last two tanks. 60/40 mix mostly city but I'm fortunate enough to miss rush hour stuff.

I'm averaging 8.1mpg with 6" lift 40" tires...was only getting 7.4 before hooking up a super chips programmer...I have it set up on performance 93 octane and my mpg improved...haven't tried the "Economy" tune" yet...doubt I will as IDE rather more power then Mpg...

What's wrong with a 3.7l?

Gearing makes all the difference since diesel BSFC is very dependant on engine speed. I was running 3.42 gears with 37's and a non-OD trans. I could run 20MPG at 60MPH (1850RPM). Crank it up to 80MPH (2480RPM) and it drops to 14MPG or less.
