But adding more oil isn’t necessary.
So, in my opinion, regardless of what the level is on the dip stick, put in 10 quarts and you are good to go. Just note where 10 quarts puts the level on the dipstick, that is your engine’s full mark.

I agree. I put in 10 quarts and leave it be. I've been lucky on this as after an oil change and all the way through the life of that oil - my level is at and stays at he top of the hash marks.
Note: I always and only check my oil level on a totally cold engine.
Nothing wrong with checking the oil level on a warm engine as long as you accept that the oil level may read a little lower than on a cold engine reading. My point is that warm or cold - do it the same way every time. That oil level becomes your car's normal. Then changes on the oil stick become meaningful.
