I tend to shift my 2021 Powerboost to "Eco" mode mainly because I'm trying to conserve fuel whenever possible. Most of my driving in highway (55+) without anything in tow. My question is how big of a difference is "eco" to normal?
Currently, I'm getting 24mpg and up. Very happy with that.

Eco sort of changes the tune but it also delays throttle input. Instead of squirting a bunch of fuel in when you roll on the throttle, it increases fuel delivery in a gentle manner.

You can reset the trip and run 1/2 a tank or so through and see if you experience anything tremendously greater/worse by only changing back to 'normal'.

I am interested as well. My current 328i BMW (2.0L turbo) has Eco and Standard among the options. If I am careful with my foot, the only difference is the coasting in Eco mode. I have done tests and at best I gained ~5KM per tank extra. Unless the F150 offers something dramatically better than just dampening the throttle pedal, I don't see use for it.

I use ECO with cruise control. The response is nice and smooth when returning to the "set" speed. I don't use Eco in heavy traffic. I cancel out of cruise coasting down hills as the F150 is a great coaster IMO.

You can literally feel the engine get de-tuned if you switch while driving. I typically run my truck in eco on my every day commute, it helps with improving mpg by atleast 1 or better mpg (atleast for me).

Seriously try it though, while driving and your foot on the throttle, switch from any of the selections and you will literally feel the truck change and see your rpms change! I think the actual biggest change is it retards the throttle response and changes the shift points on the tranny. You will really notice it if you switch back and forth between sport and eco.

I have the 2.7, and I've tried Eco. I consistently get better mileage in Normal.

Correct, it just changes throttle response and shift points, it doesn't change HP/TQ output or anything like that. I can't get into using any of the drive modes except the snow/slippery because the rest are just too situation dependent. Like was mentioned above, Eco is great for cruise resume but is bad in traffic and stuff like that. I wish Ford did their drive mode system like VW and others where you can set up profiles where your cruise resume is like Eco, your normal acceleration is Sport, your cruising is like Normal, etc. Because I would like to use Eco for cruise and that, but I hate it in other areas. Sport is nice at times for acceleration, but I hate that it essentially blocks the truck from turning off the engine when coasting down. So I just leave it in "Normal" all the time, and still get 24+ MPG.

That's good to know. This is my first F150 and I'm very happy with it. I like the options but really don't go into sport mode or the others just yet. Eco and normal for this guy

Sorry.

Yes it is , although a bit on the pricy side for coasters.

I personally wish there was an option to disable the change in throttle position versus gas pedal position, and just have it change the shift points on the transmission.

I've always hated when cars make the pedal extra sensitive just to give the illusion of power. But I can see how the shift mapping of Sport mode can be useful, especially as an intermediate to Tow/Haul mode, and how the shift mapping of Eco can also be useful, especially on long stretches of minimal speed change and minimal incline.
