You're checking your oil level when your engine's cold, right? (Or at least give it 20-30 mins after turning off so that the oil drains into the pan.) If you check your oil when your engine is hot, it may read artificially low on the dipstick because all the oil has yet to drain back into the oil pan. So then you go and add oil, and presto. You just overfilled.
