Packard engineers were among the best in the business, they had extensive labs and a world class test track. Proof of their expertise is in the service letters which have few major alterations suggested. Before I'd make a change in the oil system, the most important one in the engine, I'd check to see how other major car companies of the era designed their engines and how later (improved) engines were designed.

Today all cars have oil filters, that should answer your question
