And I fully agree.. It is the owner/driver, at the end of the day, who has
to
assume the responsibility for his maintenance diligency. (Except when
someone dogs one unmercifully and dumps it on an unsuspecting used car
buyer.)

Yeah, my sweetie would love to put that under our tree ;>)

There are some good engine test labs here in Texas, and I have gone onto
some of their sites, also SAE, but in most cases when there appears to be
data, there is first a $$ charge.

I posted earlier that I just changed my Solara oil and filter today, total
expense $19.63. If I paid $20.00 for an oil analysis, that
would be money rather poorly spent, woundnt it.....

Here is a link to the Fram FAQ, which gives a minute bit of information on
how
the filters are tested and certified....Still no hard data, but worth an
insomniac's
second glance:

Hmm, a place that makes money by selling parts and service recommends
short oil change intervals.... how surprising.
