The oil pumps merrily suck oil when it is a little more than half filled. The oil has to be circulated before the sight glass can be read. Hence it is better to be somewhat under filled than to go over the max on the sight glass. The correct level is midway, not to the top mark. It takes about an eggcup to go from bottom to top mark. The marks are to be read something like 3-5 minutes after switching off, if you wait overnight you'll see a lot more oil drained down. The sight glass is not terribly accurate, you'll never see the same level twice. So if there is oil in the glass and an air bubble above it, you're good to go.
