I just dealt with this issue after doing my first oil change. I drained the warm oil for about 30 minutes on a flat service, put a total of 4.5 L in (oil filter + pour in), thinking I had .25 L left to ease in, and I was over the F line. I had to drain some and got it right to the upper dot. Lesson learned I guess. Pain in the ass but i know it was done right.
