I wouldn’t go over 5 quarts.
I buy the 5 quart jugs of Mobil 1, and it wouldn’t surprise me if it wasn’t quite 5 quarts. I used the whole jug on my first oil change and nothing happened.
However, I had an F150, years ago, that kept showing a low oil light an no pressure. Even the dipstick would come out dry (no shit). So I kept adding oil. Somehow this caused the engine to lock up?! Trust me, the mechanic was scratching his head too. Lol
