I averaged 17.4 on my first highway 'tank'. >1000 miles on truck. No hills,,, (FLAT) Houston to Beaumont and back.

The MDS hardly ever flashed on,,, Computer leveled out at 17.1 mpg @ 70 MPH running on all 8.

'Oddly' enough, the mileage increased once I got back into Houston and ran into slower traffic on the beltway,,, computer went back to high 17's,,,

As the vehicle breaks in, the MDS is staying on longer at higher speeds.

My 09 has a rather 'subtle' "Fuel Saver" prompt in the EVIC display. Not obnoxious at all. It really does help one 'tailor' there driving habits.

Curious as to how my newly added Tonneau cover will affect mileage. I noticed last night by watching the shape of the cover that there is a 'significant' amount of air downflow right before the tailgate. If the tailgate is 'catching' the wind, a cover may help. Only time will tell
