Which car is going to appeal to a buyer more- one that says "there is no need to change the factory oil until the first scheduled oil change," or one that says "for best results, change the factory oil fill at 1000 miles." So of course the manuals all say you don't *need* to change the oil early, even though there might be some (admittedly small) benefit. And once that language started showing up in owners' manuals, people became irrevocably convinced that the factory oil contains some magic elixir that makes the engine last 5 times as long if you leave it in.
Classic case of "it won't hurt to do X" getting morphed into "you have to do X" by incomplete information.
