Switch to Synlube and you won't have to worry about startup lubrication since is binds to the parts and is always there to lubricate. There is metal to metal on the rings when conventional oils are used since they rely on the oil film to float the rings and since that only happens when the rings are moving you will not have lubrication at top and bottom of the stroke or when not rotating/moving.
Invest a few dollars in a high quality filter, with a well designed anti-drainback valve. (Eg. avoid the radioactive 'Orange Can of Death.') PureOne, Wix, Mobil, and several other 6~10$ filters are well built, and generally have a well designed, functional ADBV. You don't want the engine starving while an empty filter delays oil flow.
If you live in a cold climate, buy a block heater, and use 0w-x oil in winter. Look at the oil's pour point - the lower the better.
Those cars that were run w/o oil may have kept going, but I'm sure they were VERY torn up...
