Just did a two hundred mile run and thought my gauge was broken. On the return trip I reset the trip computer and sure enough. 26+ mpg the entire ride , including a traffic jam up for 2 miles and the a/c was on and 5 people in the truck .

3.5 Ecoboost 4x4 supercrew with 3.31 rear , set to cruise control most of the way at either 57 mph or so and the air conditioner blasting.

Got-F150?

57mph? That's one reason...

I had it set for about 65 on the way down and that's what first set me off to look at the mpg. I think over 65 mph the wind resistance and lack of Bugatti aerodynamics work against the trucks mpg lol. The sweet spot seems to be cruise control at 50-65 with my truck given its 3.31 and rim / tires. Regardless 26 mpg highway is something amazing coming from my 5.4 F250 lol

I have also seen about 9 mpg when I got all frisky and in sport mode all over the gas pedal between city lights lol.

Average speed was 48 on that trip - i'd be impressed if it were 26 mpg at 65 mph.

On the way down I was seeing 23.5 at 65mph.

Keep in mind the air conditioner was working overtime and the truck had 5 ppl in it. No load or trailer but geeeezus, This is Prius like mpg by full size truck standards any way you cut it. Even the 2.7 doesn't do much better.

I was very impressed with my ecoboost a Milagros after my first highway trip.

I was fiddling with all the fuel economy displays and noticed something though. On the instant L/100km display when I'm off throttle rolling up to a red light it says 0L/100km...but the engine is running (3.5L no auto start stop nonsense)

I don't particularly care, but it does make me question the economy numbers a bit.

The fuel is cut off; therefore 0L/100km.

Not if the engine is running.

People that drive that speed on the interstate are a hazard.
