My family has a 2007 3.3L Town and Country LX, 6000 lbs, built in trip "computer" is always +2-3 MPG over actual.... I have had it as high as 33 but I know that's not real. Right now I'm using it for the 50 mile one way work commute to Brown Deer, WI. and with the winter blend and the excessive cold of late actual MPG is around 22-23(80% Hwy at 51-55mph with cruise and some down hill coasting in OD for injector cutoff)
