2008 V6 with barely 4,000 miles.
50-mile freeway trip recently, 65-70 mph, reset computer upon entering freeway. Indicated 35-37 MPG until the very end as I slowed, for about a mile, to 60 whereupon it was indicating 40 MPG. Nice even traffic flow; no speeding up/slowing down, cruise control on most of the time. Filled up just before entering freeway and again after leaving it. With the mile or two of city streets before entring and five miles of country low-speed road before the gas station, actual consumption vs. miles worked out to about 38 MPG.
Around town - different matter. 15-19 MPG consistently.
