you are going back 50 years
you might contact WIX or another filter mfgr
and see if they have any archive data available
there was some testing in the 50's with filter only replacment (oil never changed - just tested) some used toilet tissue as filters
remember a 57 ford with 70k no oil change
just rolls of tp every 1000 or so
long - long time ago
