Re: Bypass vs. full flow oil filters

Thank you for the kind words, but it was automotive engineer and Auburn-Cord-Duesenberg member Al Light, above, who "succinctly summarizes" the pro/con full flow vs. bypass oil filters.

I post them here, followed by a few comments, quotes from
other technical folk, as i find them interesting, though my Ferrari-owning friend is a senior staff electrical engineer for a major utility company, not a mechanical or chemical engineer.

Sounds like the jury's still out, given that for all the
advancements since Packard folded, much engineering is cost engineering. Would love to hear more insight,
especially from any Packard/vintage/Classic car buffs who happen to be engineers and/or SAE members, with
access to hard, vetted studies.

I tend to agree with you, that full flow, on balance,
might be better across the board. But i'm just a curious Packard owner/enthusiast. For the occasional extremely "light duty" exercise runs many of us limit our Packards to, the above discussion, question is strictly
curiousity.

Meanwhile, the above does suggest that, especially given
the night and day better motor oils today than when our Packards were new, we are in fine fettle with bypass filters.
