Oil drains down in a standing engine.
Fuel does not burn well in the cold cylinders. Some condenses on the cylinder walls and gets past the rings into the sump where it dilutes the oil. Water, acid and soot accompany it. Engine oil includes additives to neutralise combustion products, but cheaper oils are more marginal in their capabilities. Changing the oil regularly is the best way to help.
