Mark,

I am probably showing my ignorance here, but on which side of the oil filter
is the oil pressure measured?

Thanks,

Mike-
I am making my conclusion based upon the dreadful sound that came from the
instrument console.  My manual indicates that it will sound when oil
pressure drops below a (specific, but unknown to me) threshold.  I only get
the screaming banshee from the instrument console (along with the
illuminated idiot light) when using Fram at highway speed (per my earlier
post).

So if you you are showing your ignorance by your post, I am confirming mine
here!  Given a 50/50 chance of being right (the pressure is either measured
before of after the filter point), I would guess that the determination
(triggering the idiot light/banshee) is made after the filter and the
filter's resistance to flow could cause a pressure drop that is unsuitable,
if the filter impedes flow too much (?).  Not sure.  I only trust (but
avoid) the banshee!
