Which oil filters are best?

I have not found any independent tests regarding screw on oil filters.
Just from word of mouth I have heard that the NAPA gold or silver, and
the $5 Purolator are the best.

Any thoughts or independent tests on internet you can refer me to?

After I got two bad napa filters in a row I started shopping elsewhere.
Both leaked at the spot welts on the end of the can. Another brand I
avoid is fram. I had a fram PH8A blow up at 80psi on morning a few
seconds after engine start. The rubber block gasket blew out.

I've been running super tech filters(the wal-mart store brand) for
several years and I've never had a problem. I did at one time take the
super tech, STP filters and the bosch filters and compare them for
manufacturer markings on the canisters, and found all three to be
completely identical with the super tech filter being the
cheapest(obviously).

Good luck with it.

i hear this type of thing all the time for several different brands. thru
the years I have used fram and napa filters for several diffferent types of
vehicles. never had a problem with either.

i'm not an apologist for either--besides those i have also used other
brands.i have also used delco, stp, cheapo's, expensiver, whatever...never
had a problem with any of them...guess i'm lucky.

you're probably gonna wind up hearing all sorts of responses about this
brand, not that one...frankly, they way things are these days, it seems
quality is generally *just ok* across the board, and mass-manufactured
products are prone to defects...

Now THAT's funny! I don't care WHO you are...

Suggesting that a Wally World filter - provided by the absolute lowest
bidder at the absolute cheapest price - can, somehow do a better job
protecting an engine than a NAPA Gold filter - built by WIX, a company that
engineers and builds filters for everything from a lawn mower up to the
biggest CAT construction machine going.

The WW low-bidder simply shops around for a deal on filtering media - maybe
even stuff that WIX rejected? - that has the capacity to filter out large
grains of sand, anti-drainback and max-pressure valves that maintain OEM
recommended pressures within a hundred pounds or so - if they even DO
install valves - then pays a fee to someone who has the machinery to
assemble all these crappy components.

And, don't give me that idiotic arguement about the sheer AMOUNT of
filtering media.

100 feet of window screen doesn't filter nearly as well as one square foot
of coffee filter......and, unless you have the tools to measure microns,
you cannot even begin to determine whether the filter with the larger
amount of filtering media actually filters better than the one with less.

*** Please, PLEASE! expand on the so-called "manufacturer's markings" you
refer to above. I'd be REALLY interested in hearing that one.

I have compared Bosch gas filters that way. The 'cheap parts' stores
sell them for $12.00 and Volvo sells them for $45.00.

Same part number in the same box.

Same for GE lights. The 'GE' brand ones were double the 'store' brand
and when you opened the box, the bulb in both had the same markings
exact up to including the 'GE' stamp.

Super Tech are made by Champion Labs, they are actually a VERY good
filter. The also make the Lee, Deutsch, Champion, STP, Bosch, some AC
Delco some Motorcraft some Mopar numbers.

Yes Wix are good as well BUT, NAPA filters are not all WIX the Gold
line are WIX the Silver line may or may not be depending on the part
number I run Wix or Baldwin.

Fram filters are crap. Cut one open next to a Wix and I would be very
surprised if you did not agree. Under severe service they sometimes
collapse and block oil flow. The glued-on cardboard end caps are less
than impressive as is the piece of string that bundles the media.
BTW -- Pennzoil is Fram. I use Wix in my circle-track car. My buddy
used to use Fram until he lost oil pressure and found the inside of
the filter ruptured and blocking 99% of the oil flow. Fortunately the
1% saved the engine from immediate death and he was back on the track
with oil pressure after putting a different filter on. I had tried
to tell him about Fram -- not the first time I have heard about this.

Cut some open and see for yourself.

First of all, don't rely on reviews that include no real testing but
instead only take filters apart to show the insides. They're not tests
but merely beauty contests.

I know of only 2 independent tests, this one done 11 years ago by a
Finnish auto magazine:

www.mr2.com/TEXT/oil_filter_test.html

and a Consumer Reports review published in their 2/1987 issue, with a
follow up a few months later.

Purolator and Champion Labs make many brands of filters. Purolator
seems to make them all to the same standard, but with Champion Labs the
quality varies according to the customer's requirements and willingness
to pay.

If you want a better filter, try Fram Toughguard, Mobil 1, or Purolator
Pure One. These are made primarily of synthetic fiber rather than
cellulose and are claimed to remove at least 96-98% of the 20-micron
particles in a single pass test, compared to 70-94% for most
conventional filters.

I use Wix or Hastings.

Stay away from Fram unless you want your filter made from cardboard.
