My best mileage has been on two long highway trips.
#1 - all highway, cruise at 65 MPH, possibly slight tailwind, premium 93 octane, 45.0 MPG over 486 miles
#2 - highway and country roads, cruise between 55-65 MPH, not sure on winds, premium 93 octane, 41.8 MPG over 492 miles
And I just thought of something else, because a friend did this for a while without noticing... do you drive in S or D? S will only go up to the 5th gear, and kill some MPGs. Often times I'll drive in S in city, but shift to D for long stretches to take advantage of the 6th gear.
