There is a great write up on what happens on 360/430 Ferrari applications on cold fills until it reads correctly on the dip stick story. MASS Air Flows wasted, hydro lock, etc as that application is a wet sump I believe.

Good info. I never knew about the spec for it to be warm. For most cars, in my experience it is to be cold, with plenty of time to all drip down to the oil pan.
Here's the page from the owner's manual for my 2001. Regarding top mark vs. midpoint between the marks, I can see how it can be read both ways. I'll continue to fill to the top mark.

The manual is not explicit but there is plenty of documentation elsewhere that 'full' is right in the middle but that the engine is designed to deal with 1/2L extra oil. There is no issue with having an extra 1/2L so filling to the max is not a problem unless you fill to max when cold which is definitely over the max line.

Makes you wonder; is the correct amount the actual quarts/liters put in or the line on the dip stick. any chance not the original dip stick and yours is too short ?

In 40 years of goofing with cars I've never seen a manufacturer spec the oil level cold - always hot (after a short drain-back period).

https://www.cartalk.com/content/when...-your-oil-when It's a trade-off: Cold, first thing in the morning, will be more accurate, since all the oil had all the time it needs to drip into the pan. The thermal expansion effect may be more stable too for most climates. But most people don't even think to open their hood unless they're waiting for the tank to fill at a gas station with nothing else to do, so checking while warm after a few minutes is better than not waiting, and better than never checking at all. But it does matter, since the spec level on the dipstick should read differently depending on which method is specified. From the cartalk thing there, the manufacturers are on to this. Yes, the lazy-people / warmed-up method is the new norm. Check your manual if in doubt. I always understood the tradeoff, but was unaware that manufacturers had (all?) chosen to go with the warmed up method. My 911 has to be warmed up, level, and idling while I check, just like most automatic transmissions. But that's different. And it has an accurate oil-level gauge on the dash too.
