'07 Adventure, completely stock. First couple tanks were in the 17mpg range, now I'm getting maybe 15 - good mix of city/hwy. Not sure if it's cold weather or winter gas or what, but it's a bit disappointing.

My '07 H3 3.7L/ATX Lux/Adventure gets 16.5 city/20.5 Hwy @ 70-75 MPH (tires @ 5psi under max), In winter, I lose 1 MPG city and at least .5 MPG hwy (depending on road conditions) (I have lots of data and check with every fuel fill since new).
You can really help or hurt the MPG on the auto. depending on how you drive. Best case accel moderately and tip out of pedal for early TC lockup in city and keep your pedal movements under control Hwy. + stay out of cruise on rolling grades(-0.5-1 mpg)
My '08 H3 3.7L/MTX Lux/Adventure gets 18.5 city / 19 hwy(was expecting more and it should do better but those are the raw facts) it is still under 4k miles.

Stock '08 Adventure w/winch normally driving 75 mph on the highway, I usually see 14.5 to 15 mpg.
Hey, that's not too bad, my '05 Silverado 4 wheel steer crew cab gets around 13.5 to 14 on the hwy.
My '99 Vette, on the other hand, gets over 30 mpg with the cruise control set on 80 mph.
