FYI:
There is no noise because of the style (function) of the bypass valve used
in Motorcraft filters.
The upside to that bypass valve is it seems to flow more oil while cold.
The downside is while it is opened (every cold start or when the filter is
otherwise clogged) it flows totally UNFILTERED oil through your entire
oiling system.
Some Ford NUTS I know will not use Motorcraft filters because of their
bypass valves, I still use them myself....
Here is some comparitive info of the internet...
These particular filter moldels are for the SHO not the V-10...
Motorcraft - FL400S
The Motorcraft is made by Purolator for Ford and is the replacement part you
can expect at dealerships. The sample we purchased was only $3. Unlike the
Purolator, the bypass valve was on the other end, as per Ford specification.
The shell was as thin as the Purolator, or no thicker at .0085" which is
nominally the same given the possible errors measuring the wall thickness of
a curved can.
The filtering media is paper, I assume of tolerable quality. They use a lot
of it, (204.5 sq. in). All in all, it is a well made product, but it is made
to be sold as inexpensively as possible. The PuroOne has the bypass on the
other end but perhaps better and more paper. So which one is the better of
the two? I don't think the Puro is twice is good but these two filters,
mentioned first, are at the bottom of the list.
One thing I learned about Ford oil filters is that they use better oil
filters (from another source) at the factory for the owner to use as the
engine is being broken in. Thank God!
Mobil 1 - ML209 (& M1-301 oversized)
Mobil 1 oil and oil filters have long had an outstanding reputation. The
filters have a synthetic element media and the strongest shell on the
market. The outside shell is .0195" thick on the large ML-301 or .0170"
thick on the smaller ML209. Mobil 1 is maybe the most forthcoming with
information since for a long time they have been the 100-year-old scotch of
quality oil filters. They are proud of their "Hydrostatic Burst" values
which are three times the SAE standard. Their "Pressure Impulse Cycles to
Failure" values which are the highest, and only ones I have found; which
mean the guts of the filter are made like a tank. The whole filter is an
engineering exercise in loving design excess. Is it the best oil filter made
or has anyone come up with a better design while Mobil 1 has rested on it's
reputation? Lacking extensive and expensive laboratory tests I can only say
Mobil Oil filters are somewhere in the top three, in a class of outstanding
over achievers. Like all top shelf oil filters the going rate seems to be
about $10 off the shelf or $9 if you can cheese a jobber price.
