You just don't know how much is left In the engine On the initial drain.
Wonder how many actually precisely measure the oil coming out...for me, I put in 9 qts and then small amount from there. So far with 3 oil & filter changes, it's been between consistently 9.7 to 9.8 qts. Again, FOR ME is all I'm stating. I do check the next morning to see and so far, haven't needed to add anything. My dry sump Z06 usually required a slight amount more the next day. Of course, that's dry sump VS wet sump LT4. I was just stating that the manual states 10 qts...hope the factory would know how much it requires...
