Essentially he had oil changes quite regularly without the benefit of a drain.
Yeah had the oil consumption been less than 1 qt/10k miles, then that would been impressive. At 1 qt/1k miles he was replacing all the oil every 5-7k miles. Not too impressive really. Today's SM Group II oils have come a lot closer to todays Group III synthetic. Apparently Mobil 1 was mostly PAO with some ester back then. But I guess the Group III is about as good.
