Quick update. I had my dad over to help me put up 25 sheets of OSB and do some siding on a barn extension today and I drove his truck to lunch again.
To date it has average 17.2 mpg. Its a 2011 F-150 Super Crew 4x4 Eco Boost 4X4 with the 3.73 gears. His longest trip to date is about 55 to 70 miles, retired and does not go far. Average trip is 4/5 miles each way to town so about a 8/10 miles round trip. It also has factory remote start and he said he has used it just about every day this winter for a good 10 minutes in the garage. Yes, he opens the door first, but his garage is unattached so he keeps his second opener on the kitchen counter where he can see the garage door open then start the truck. Anyway, it has right at 10,600 miles on it now.
