Thanks for posting this, I had no idea.

IIRC, the Continental O-300A used in this particular 172 has, at best, a 1,500 Hour factory recommended TBO. I guess you are skipping the startup wear that piston engines normally endure during a startup
Wonder how they changed the oil? No way they could have done it without some sort of setup to allow an oil change in flight,. especially on 1950's vintage aviation oil.
Wonder what kind of equipment failures they had during that time?
They said they arranged the oil lines to be checked and oil added from the cockpit, so it would be simple to drain a small amount overboard while adding fresh oil. Never do a complete change, just a slight replenishment along the way.
At the end, they had lost the generator, tachometer, autopilot, cabin heater, landing and taxi lights, belly tank fuel gauge, electrical fuel pump to transfer fuel from the belly tank to the wings, and winch used to haul the fuel line and supplies up.
Imagine doing this 128 times!
