Oil usage?
2020 F150, 5.0 Liter, 39k miles. Bought used. I've noticed some oil usage. A few weeks back I added about 1/2 quart. Checked it today and it's low again. Almost due for oil change. Any thoughts? Thanks.

The latest version of the 5.0 has plasma-coated cylinders that have been problematic for some. A 2020 should have the mods done to address the issue, but it's not universal. You may want to start a case with your local Ford dealer to determine if your 5.0 is a problem child.

1/2 quart low if none added between oil changes is going to be considered normal. Question is how much are you adding versus miles driven.
Acceptable is generally considered by Ford to be less than 1qt/1000miles.
That said, personally I’m only ok with 1qt/~5k miles on a newer vehicle. My truck (the old 5.0) was doing about 1/2qt of 5W20 in 4K miles when I bought it with 35k miles on it. I’ve run it hard towing, and switched to 5W30, and found that rate actually dropped. But our motors are different.
As the first response stated, some use is considered normal. If you are concerned it is excessive, dealer can run a usage test - they are just looking for how much oil it eats versus miles driven though, so you can do the same if you don’t want to rely on them. Get it documented and get them looking at it if you think there is a real issue though.

Sometimes after an oil change, particularly one done at a shop, it could be half a quart low to start. Worth checking it the very next day after the oil change, filling to exactly the top of the hash marks, and then you have a very well known point to work from.
It's a paid in the butt tracking down this stuff, but you want to start by eliminating as many variables as possible, and a "short fill" after the change could be a portion of your issue.
