re 599 Motor Oil change .. Quantity of PAO additive

Dear all,
I just found this paragraph from the Service Manual.
It clarifies how much oil she should get in every oil change.
11.7 L of the specified oil + 800 g of PAO additive.

I had some kind of obsession with overfill. Sorry about that

Fill the system with 11.7 l of the specified oil.
The quantity of oil required may vary slightly relative to the amount indicated for filling the tank when empty; this is due to unavoidable pooling within the system.

Refill slowly and do not exceed the reference notches on the dipstick.

Fully tighten the oil filler cap on the tank.
Start the engine and leave running at idle speed to reach a temperature of 95°C (approx. 10 minutes after starting).

PAO additive must be added to the lubrication circuit at each engine oil change.

Unscrew the oil tank cap and add, pouring slowly and in small quantities at a time, 800 g of PAO code No. 232571 additive to the tank (filling process should take about 10 minutes to complete).

Check that there are no oil leaks from the draining caps and the filter cartridge.

Check the engine oil level ( A3.01). Fully tighten the oil filler cap on the tank.
