Tolerances on a 72 were so large and there was little to no synthetic oil available, he did what was right at the time, and even better, using Pennsylvania grade crude, which was always a better oil choice in my book. QS even ran a lifetime engine warranty for a while if you did exactly what your dad did.While there is a difference, it has more to do with how the engine was maintained.
My dad bought a 1972 Chevy Kingswood station wagon brand new and it lived on Quaker State for its entire life, he changed the oil every 3000 miles and drove the car for 280,000 miles. In the 80's I took the 400 small block out of it and rebuilt it, the engine looked like brand new inside - no wear on anything except the timing chain was a little loose - it deserved to be after that many miles. Had the crank polished (didn't need it but did it anyway), dingleberry honed the cylinders (no taper or ridge), and slapped it back together with a nice cam and continued to thrash it for another 100,00 miles in my El Camino before selling it.

Those were the best from the PA oil fileds, better than the Oklahoma and Texas sourced oils. We had different dinosaurs east of the Mississippi -
