Oil Change Frequency

...ummm....splain sumthin Lucy...... if the oil sitting in the pan collects moisture all winter, and the acids rise to the top, why put new oil in to collect moisture/acid film over the winter? Let the old oil do it. If moisture and acid are that great of a concern, shouldn't you change the end of the season new oil for more new oil at the beginning of next season? Unless I'm missing something here, besides a few brain cells that tree limb knocked out of my head years ago, seems a waste?
