Definitely impressive and shows dedication to MPG. Personally, I don't have the patience for that. Interstate driving for me is often the speed limit in the city (55MPH - 65MPH), but I'll often hit 75MPH - 85MPH in the country. I'm also not conservative on surface streets, but I'm also not Speed Racer either.
According to the truck (I don't care enough to track mileage by hand), I'm averaging 19.2 - 19.8 consistently with my 3.5EB and 10-speed. Driving mix is 60% city / 40% highway. That's pretty consistent with what I expect, but I am curious what it would be if I actually altered my driving habits.

I wonder if hypermiling could have an adverse effect on engine life? In my experience you're always lugging the motor (running it at very low rpm's). It even says in the manual to "not labor the engine during break-in miles".
Can you comment on this? (correct me if I'm wrong)
Haha, I'm averaging about 14 or 15 these days, maybe down as low as 13. Damned stop lights kill my FE on a daily basis. As soon as I get on the highway, I average 18-22, with spikes up to 26-30.
living in the DFW area, if you drive only 65 on majority of these roads, you will get ran the hell over
Same in the country out here in Kansas. People do tend to drive slower around Kansas City due to enforcement, but speed ramps up considerably in rural areas.
On my 14 I found doing 55 MPH gains 24 MPG hand calc, but it is so hard to stay at 55, even though that is the speed limit. I can do 64 and be passed, which is fine by me, they will get pulled over, not me. The county mounties where I drive will let you slide 9 over, but do 10, and the lights come on and they WILL write you up.

What's always fun for gas mileage is speed limits of 75. Go 75 in a 75, and you'll get your doors blown off while also getting low gas mileage. Gotta stay up around 83-84 to maintain pace with traffic, while also watching your gas drain away.

Nope, I agree, not good for the engine. However, I never knew of an engine that failed for being too gentle, using standard oil that met specs, using non-T1 gas and only a few over the years that were tuned and raced. With the turbo/DI it may not be aligned the same.
I will say, that I even redlined this engine during this trip. I will get on it when needed when pulling out in traffic. That definitely hits mpg especially when tracking around 30mpg.

I wouldn't even think of taking it easy other than being in a truck. I drove a Vibe for a long time, that I drove aggressively. Now I can set my cruise at will and most won't like to eat my ball mount or not being able to see.
And driving like this is a PIA, I only did it based on recent numbers and see how well I could achieve.
It was bound to happen by somebody and a matter of time for me. Mileage info over last 700 miles since last fuel up:
I was going to wait for a 1 year review of the truck, but this seemed worthy for a seperate topic. I've been using Fuelly since day one, can be found at the following link or searching "Blue Flame"
Truck is basically stock, shown at bottom of signature, only add ons are a rear cover, Anzo lights, bug deflector and seat covers. The Fuelly number in sig was before I started towing the boat for this season. Truck is calculating about 1.5mpg overall higher than what is hand calculated. Here is the last Fuelly input for the record that gives 27.4mpg which is 1.8mpg lower than the truck:
The 100% city cycles noted are when I tow with my boat. As you can see, the mpg have been relatively high and was a matter of time when traffic was good, weather cooperated and didn't have significant construction to deal with. I work 42 miles away, about 60% highway, 30% what I call boulevards (Telegraph/Lapeer Roads for those familiar) and 10% city. I don't exceed 65mph on highway, go 5mph faster on rest of roads to make lights.
My previous fuel up hit 980 miles to empty, so I had the mileage and fuel economy rolling good. Note, you can't get this number by simply filling up, coasting down hill for 30 miles and filling up at bottom of the hill. Your DTE numbers use previous mileage for weighted averaging.
Full discolosure - I do work for Ford in case anybody asks, but I'm here since I love F150's, had one since '97. I am glad to give information that is publicly available and common practice what I know.
Similar vehicles, and we both work for Ford.
I wish I could get numbers like that. I have the 36 gallon tank and only get about 500-600 miles per tank. I average 19-19.5 mpg usually.

Who cares about "getting your doors blown off", that's kind of a dumb statement anyways. There's so much photo enforcement here that I do a couple over the limit, that's it. If people want to pass, they can pass, I don't care.
Dirty looks just get a middle finger in return lol There's plenty of lanes for people to play Fast and Furious in.
