You are correct, the maint manual says "Pour in approx
of fresh oil." Drops you off there, never saying to add to correct dipstick level or whatever.

The system holds approx. 3 liters but when you do an oil change you are not fully removing all of the oil from the system.
A refill usually only takes about 2.5 L.
