Not trying to get into a peeing contest, but water evaporates off your kitchen floor because it's in an open environment and the relative humidity is less than
100 %. Temperature plays a role in this also, but to what degree I don't really know. The oiling system in an engine is closed and not exposed to the outside environment . To test this, put some water in a jar and close it tightly. The water won't vaporize. The same for the inside of your engine. Thus, you do need to get the
oil up to 212 degrees to boil off any water and other contaminants.
