Ditto here - bought my '87 new, have 105k on it; have exclusively used
Mobil 1 since ~50k miles (Redline B4 that, after break in), and always used
Fram 2870A filters. I can't prove it, but I'll bet that since the oiling
system is full-flow through the filter (as opposed to bypass) that the
Frams have *more* filtering ability than other filters, causing a
'rstriction' which would cause a pressure/flow drop to below acceptable
levels if the downstream engine parts are too loose (and the pressure
switches, along with the rest of the engine, come after the filter, so of
course they'd see the pressure drop).

If the above is true, perhaps a valid check of your engine's condition is
to run a Fram filter w/ 15-50 and if your oil lights/buzzer fire up the
engine's tired!!(?)
