Both on original motors, never been rebuilt. I am religious about doing oil changes every 1500-2k miles. I do them myself, less than $25 in oil + filter, and about 20 minutes of work.
Take it for what it is worth. That is my personal experience, and I am sticking with it.

Changing at 10,000 most likely would create the same result.
You could change every 500 miles but there would not be any real proof it was necessary.
Do you change your belts and tires annually too?
