It's a 2 qt crankcase fill. No more, no less.
The reason your dipstick misreads is due to installation angle....the oil pools higher towards the lower section of the pan. Or, as someone else suggested, you have the wrong dipstick....which is very, very, doubtful.
Too little oil is bad. Too much oil is much worse. The increased pressures can damage seals, rings and other very sensitive expensive parts.
