I'm wondering why you guys don't get the fuel economy. I haven't reset mine in two months so it includes a LOT of idle time and it's at 18.7 mpg right now. 3.55 gears.
If you go 50 to 55 mph then yeah you'll get around to 20mpg with the eco....who goes 50-55mph these days besides granny and gramps. Would run 87 no ethanol almost all of time in my eco (as I do with tundra) and the only time i was getting good mileage (18mpg or better) was with the wind on my A$$.
If Speed Limit was 55 mph - I would run 62-65
If 65 mph - I would run 70-75
If 70mph - I would run 76ish
If 75 mph - I would run 80-81
So this explains why I would never get the "20 mpg" with my Eco prior to selling it. In the city i didn't drive around like an old grandpa either I guess. Same goes with my tundra for all the above stats, I would say i averaged 1mpg better with the eco vs my tundra(maybe 2, no more though).
The stats the advertise on TV for mpg a lot of times are for 2WD pick ups, who buys those anyway. Anytime you read the window sticker take the low number and that will be your closer to your mpg
