Come on Wrascal - Josef simply posted that he averaged 29 & 27.5 MPG on a specific road trip. And that he drove "gentle on the throttle".You observed Hondas (open road, easy/ steady pace) momentary peaks, not a true long distance average.
The only way to know your true MPG numbers are to consistently track it (mile after mile, tank after tank).
He confirmed that he posted Honda's trip computer number, and I don't doubt him.
I also believe he may have achieved close to those figures, too, be it your Fuelly app or pencil, paper, and long division.
Josef posted about a single trip, not his average MPG of time. Careful driving and throttle management can yield impressive results.
After purchasing our Passport, after it's 165-mile drive home, with careful driving; Honda trip computer stated 28.5 MPG.
Tank filled at dealership immediately before leaving; 164.6 miles trip home; all highway; 55-60 MPH; gentle road; fillup at gas station immediately before arriving home (5.84 gallons, $16.90); Pencil/paper/long-division results: 28.185 MPG. And yes, I track every fillup & maintenance in my little car book.
Very likely Josef is a better driver than my wife, too (hope she doesn't see this post)
