You might want to take a look at an independent oil filter

Changed my mind about an old favorite of mine!  (Won't be
buying FRAM again).

Good objective info on this subject has been hard to find,
and I really don't like buying on faith.

With all the talk about oil coolers failing, it would
probably be a good idea to examine this often overlooked
part also.

    I think this guy is full of it.  It sounded real good at first,

until I

pulled apart several filters myself.  I did not find what he says
he found.  Either Fram has fixed up their filters since he wrote that
or his is full of it.  My Frams seem at least as well made internally
as the filters he says are "better".  I have been running Fram HP1
racing filters on my Long EZ for over 700 hrs with no problems.
I tear down every single filter and they have all looked fine.

I was very concerned for my auto filters (all Fram) when I read
this stuff, but have since compared several filters and seriously
doubt there is a problem now.  Wonder if there ever was a
problem.

I use the HP1 too and it is a good filter.  This is not the same as saying
that all Fram filters are good (I don't know if they are or not).  The HP1 &
HP2 are not typical automotive filters.  They were intended to be
transmission filters capable of handling higher pressures than most auto
filters.  You probably noticed that they are heavier (wall thickness is
higher) and I'm SURE you noticed that they cost about 3 - 4 times as much
:-)
