My 2021 5.0 has no indicator lights for the cylinder deactivation and is totally seamless in operation. I also have zero oil consumption issues. 5k on the truck so far and I hope it stays that way.

And (unlike the case for Chevy and Dodge trucks for example) there is also no mention of it in the 2021 F150 spec. sheet or on the build page.Ford has been very quiet about cylinder deactivation, nothing in the owners manual, I have done a pdf word search and found nothing.
Speaking only for myself, I can say that I'm not "hostile" about cylinder deactivation per se at all. It's Ford's engine and they can do with it whatever they want. (For all I know, years from now it may end up being deemed a well-engineered, economically and environmentally worthwhile modification, and I hope it does).Not sure why every is so hostile about cylinder deactivation, it's a proven technology that's been around for decades at this point with other brands. There's about 9999 other things that can go wrong with all the tech stuffed in these trucks, I wouldn't worry about cylinder deactivation.
That's absolutely not my opinion. I feel it and hear it. I have exhaust mods so a factory exhausted truck may not hear it.I just picked mine up on Friday and only have 100 miles but there is absolutely no difference in how the 5.0 drives with cylinder deactivation.

I have read up on those oil consumption issues.
Quite a bit of this was all but eliminated going to a heavier oil.
I guess Ford was using 5-20 and for 2021 changed that to 5-30.
(Super small oil droplets making their way into the intake via PCV)
Another thing that was noticed. Supercharged 5.0 were not having the issue.
Could be due to the fact that the supercharger people require a minimum of 5-40 to maintain supercharger longevity.
Ford, in their infinite wisdom started replacing dipsticks with longer ones and adding a quart of oil to the crankcase. Hah hah hah hah hah.
I have several old cars that don’t use oil between changes (5000 mi).
Not my 66ElCamino with a never touched 73 307
Not my 200,000 mi Chev truck or Trailblazer.
My 65 Ranchero uses a little between changes, but I tend to drive that thing a lot harder than the others —too much fun—300hp, skinny tires, and a 4spd, this car can party.
Anyone saying even a qt of oil is acceptable in 5000 mi under normal driving is blowing smoke up your hiney.
Towing, hauling, or severe use—different story
That mileage will improve rapidly. Congrats on the new truck ?Around town I am getting 12.2 and I am being very light on the throttle during the break in period. Most of my driving is around town, I have done a couple, meaning three trips, that I hit small highways and average speed of around 55-60 for 20-30 minutes each. So 98% of my driving has been around town. I have ~600 miles on the odo.
I have not seen any indicator on the dash but again I haven't really driven on the highway to much.
do you mean MPG or L/100K? that's about what i'm getting in L/100KM which is something in the ballpark of 20MPGAround town I am getting 12.2 and I am being very light on the throttle during the break in period.
