My thoughts about not changing the oil.
It is my belief that you should still do so to get rid of the crud that builds up in the pan that doesn't necessarily get floated and sucked up by the pump, build up that could possibly plug the pickup screen.
[edit]
Maybe not as often and when it's already low on oil.

Well I just did a quick calculation.
Assuming 100 miles at 2000 RPM with 0 boost, the engine would suck in 42 million cubic feet of air.
One quart of oil in 42 million cubic feet of air (315 million gallons) is almost a non existent oil presence.
After looking at those numbers, you would not see any MPG change either.
Before the overhaul, my consumption was over a gallon per 100 miles at highway speeds.
Fill'er up with oil and check the fuel.
As far as doing an oil change, you could extend the change interval but I would still do changes.
Get the sulphate's out of the crankcase that can combine with water to make sulphuric acid and also get rid of the soot before it starts dropping out of suspension.
