First tank on the all interstate 240 mile drive home from the dealer was 32.68 hand calculated, 32.4 on the trip computer. The second and third tanks which were all 55 MPH back road and interstate commute to work with very little city driving were 31.5 and 31.2 hand calculated with the trip computer reading pretty close each time. I just didn't write the readings down. Almost all interstate driving is with the cruise set at 68 MPH.
All of those are with one occupant and no cargo windows up A/C on with temps ranging from high 50s to mid 80s.
