Through normal operation your engines blow the first quart overboard ending up on the wing and the flaps. I could tell you that this was a design by Lycoming in an effort to prevent corrosion in those areas, but that wouldn’t play very well, so we won’t even go there! Seriously, it’s nothing to worry about, as long as your engine does not have a history of excessive oil consumption.
