Oil filters for Duratec 3.0L
Ford’s P/N is F1AZ-6731-BD
September 2006
NOTE: ALL OF THIS IS SUBJECT TO MANUFACTURER CHANGES AND SOURCING ISSUES SUCH AS INVETORY AND SUPPLY LINE CHANGES. IT IS RECOMMENED TO VISUALLY CHECK THE FILTER EACH TIME FROM YOUR SOURCE.
Motorcraft FL-820S (Walmart $2.35, AutoZone $4, PepBoys $5).
This filter appears to be made by Puralator as external construction looks almost identical. The holes in the base are elongated and it uses the preferred Silicon ADBV with S on end of p/n. The bypass valve is in the base. It is speculated by some to have better particle filtration by using the PureONE media.
Champion Labs is an OEM supplier to Ford and is the probable source for the filter that comes on the engine from the factory. They look different (light gray) than the MC. Champion may have a patent on the base bypass design and share it with Ford. I have also read that a Champ version was distributed at some point by Motorcraft as the FL820(S?).
Purolator PremiumPLUS L24651 and PureONE PL24561 ($3.50 / $6 Pepboys)
www.pureoil.com
The construction looks like the FL-820S except the bypass valve in the dome, not the base. Both have the red Silicon ADBV. They are considered by others as moderate flow rate and the PureONE is very well regarded on particle size. They claim 98% multi-pass efficiency for PureONE and claim 10-20um filtration for the lower PremiumPLUS on website. They call the better media Micronic.
Purolator was/is owned by Arvin Meritor who has signed an agreement with Bosch and Mann to sell it and be run as a joint venture. See
www.arvinmeritor.com. Watch for any changes.
Bosch Premium 3410 ($6 Autozone)
http://www.boschautoparts.com/Produc...OilFilters.htm
This was observed to be identical to Purolator with red ADBV and dome bypass. 98% efficiency is claimed on the box (microns?)
WIX 51372, Napa Gold 1372, and Carquest 85372
($3 by case
www.fleetfilter.com , Napa ~$6, Carquest $7)
www.wixfilters.com
WIX (Dana) is well regarded filter company. I looked at the Napa Gold version and the bypass valve is in the dome, the ADBV is red Silicon. WIX website generally claims bypass is in the base but when I checked it was also in the dome. Flow is rated at 11-13gpm, 19 micron nominal, and bypass valve set for 12-15 psi. Right now WIX website says they are using “paper” on the 51372 but I would watch them for improved filtration material.
WIX also has general information on “Glass enhanced” media good down to 10-20um and is specified in some other oil filter applications. They call it “depth” vs. “paper” media. On a Napa web site I found “T-03 Glass Enhanced Media” for the Gold 1372 (FIL1372) and NASCAR version (NFI91372, $3.70) uses “T-52 Synthetic/Cellulose Media” with black ADBV and dome bypass. So who knows ? I’ve emailed Wix twice on this to clarify but no response.
Mobil M1-210 ($11 Pepboys/Kragen)
www.mobiloil.com
M1 appears to be the first major brand claiming synthetic filtration. This filter is well regarded by many but may not have the flow rate of the K&N. It has small holes in the base plate and stamped ZZ. Silicon ADBV is there but bypass in the dome and set for 9.5psi. They appear to be made by Champion Labs and claim 99.2% under SAE J1858 Multi-Pass Efficiency Test (microns?).
K&N HP-2010 ($9 online, $12 Kragen/Pepboys)
http://www.knfilters.com/search/prod...x?Prod=HP-2010
K&N claims high flow and excellent filtration using phenolic-resin impregnated cellulose. Construction looks identical to the M1 externally and Champion is probable manufacture. Even the ZZ is stamped on the base plate. Red Silicon ADBV and dome bypass. They claim the ”Performance Gold line is from 12-16gpm ‘capable’ of trapping 10-20um.” based on the larger HP3008 filter, so I suspect it’s ~14gpm.
Ford Racing CM-6731-FL820 ($14 online)
http://www.fordracingparts.com/parts...tKeyField=7567
Ford says it has Silicon ADBV and Synthetic-Polymer/Cellulose-Fiber blend media.
Champ Labs PH820 (Luberfiner)
www.champlabs.com/products/oilfilters.html http://www.servicechamp.com/prod_res...es%20Sheet.pdf
($3each+$5 shipping on Amazon.com)
ECORE was a new construction technique which can be seen on their above website. They have a “patent” claimed on integrated bypass/ADBV on the base plate which is also shown. I have not seen a PH820 but I have seen a SuperTech and AC Delco versions. A Champ document claims the design is tested to 96/94% single/dual pass per SAE HS806(10-20um) / J1858(20um) using media 9668. www.servicechamp.com/prod_res_docs/Ecore%20FAQ's%20Sheet.pdf
AC Delco PF1250 ($3.50 Pepboys)
http://www.acdelco.com/parts/filters/oil-filters.htm
This was found to be a Champion Ecore design. The filter height was reduced by about 20%. It had a thin backplate and a second one added for easing blind installation. The bypass is in the base with black ADBV. The most unusual aspect is you see the pleats inside. A black plastic cage held them in place; maybe 90% open, unlike others using a perforated metal tube. See the diagram of Champ filter on their website above, item labeled “nylon core”. I have also seen a reference to a PF1250CL listed as “Classic Design”.
FRAM PH2 and Pennzoil PZ-42 ($5.50 Kragen)
www.fram.com/products/oilFilters.php
These appear to be the same with “2S” stamped on the base plate and black ADBV. The bypass appeared to be in the dome and valve may be plastic. The PH2 box claims 96%/94% single/dual pass efficiency per the manufacture, Honeywell, testing to SH806 J1858 spec (microns?). FRAM MH2 ($9 Kragen) physically looked like the PH2 but had a plastic insert in the outlet hole to hold the time release TRT additive for this “high mileage” version.
FRAM TG2 ($7 Kragen, $5 Walmart)
The box claims it is synthetic glass/cellulose filter and has 99% efficiency for >20um per Honeywell testing to SH806 J1858. This Tough Guard had the red Silicon ADBV also. The bypass in the dome is probably plastic and the box said a bypass screen was included.

Since these are 22x1.5mm metric threaded, perhaps look for European filter manufactures of truck filters.
MY EXPERIENCE
My relevant experience was on a 1997 Chevy Tahoe, 5.7 liter. I ran Castrol 5-10W30 dino for over 100K miles using primarily low-end FRAM filters. OCI was 3000 miles except 3 runs of 6000 miles using Castrol Syntec 5W30. It consumes no oil in 3000 mile changes at 137K miles. It used 2/3 qt during 6000 miles using the Syntec. This was primarily local driving, i.e. a mom’s truck. My conclusion was I could use almost any filter in 3000 mile OCI.
SO WHAT FILTER ? (warning, this is based on lots of opinions)
It depends on what is important to you. In February I got a new vehicle with Ford’s Duratec 3.0l engine and want to get results similar to my Tahoe but using full synthetic 5W20 and 5000 mile OCI. Ford warranty requires 5000 mile OCI. Motorcraft 5W20 blend is recommended by Ford but both dino and full synthetic are accepted.
ADBV – I never had a problem running 5W30 oil with black Nitrile with sideways mounted filter on the 5.7l engine. The red Silicon appears better especially for very hot/cold climates. If I have a problem at start-up I’ll worry about. So silicon ADBV is minor consideration to me for now.
Bypass valve location is better in the base especially if the filter got loaded and ran into bypass a lot. If filter goes into bypass only temporarily, such as start-up and occasional high revving, I don’t care about location since the filter is horizontal in my application. (I would worry if the bypass vavlve was hanging downward with filter base up.) I may care if I was sever duty or hard-driver but then I would then be more concerned about flow rate and bypass psi.
I read some findings on particle count/distribution after 5000 miles showed PureONE media did an excellent job, slightly better than the K&N (caveats abound). A PureONE type filter is expected to have more media stuffed into the can resulting in much lower flow rate. If I’m sever duty or hard-driver, I feel the K&N may be a good trade-off as one Mazda hard-driver (Duratec) indicated better UOA compared to FL-820/PureONE. Then again I may just do OCI at 3000 miles as recommended by Ford for sever duty.
My big concern is filter load-up with these improved media resulting in filter bypass. I have some experiments planned for this but will take awhile to get actual road results.
