[Mgs] Paper or Felt Oil Filters

[riverside]

Smokey Yunick's rule of thumb was 10 psi/krpm measured at
the "end of the line"
my alfa 2L in stock form makes oil pressure like your V8.

I like spin on filters  -  Wix to be specific.  not hard to cut 'em open for
inspection.   I have converted many Brit and Italian cars to spin on
and have not noticed any oil press drop when using the Wix filter.
