I just want to point out that Oil filters are more important than the oil, if you don't have clean oil what the use of buying expensive synthetics?

Many newer Fords specify a Motorcraft FL820S Oil Filter for the engine. Is this the best filter for the job?? Inquiring minds want to know (or at least I do).

Group 1 (My personal favorites)

Ford Racing CM-6731-FL820
Motorcraft FL-820S
Royal Purple
Purolator PureOne PL24651
K&N HP-2010

Group 2 (Filters I might use)

Fleetguard LF16002
Denso 150-1014
Amsoil Ea011
Wix 51372
Mobil 1 M1-210

Group 3 (Filters I'd rather not use)

Donaldson P550965
Motorcraft MFL-820
Bosch 3410
Purolator Premium Plus L24651
Fleetguard LF3681
Hastings LF110 (aka Baldwin B329 / Casite CF-110)

Group 4 (Filters I won't use)

Pro-Tec 159
Pep Boys ProLine PPL-24651
C.G.Enterprises Viper 2 Oil Filter
Advance Auto Totalgrip AA2
Fram TG2
Fram PH2
Walmart ST2
STP S2
ACDelco PF1250


I found the same results at Bob is the Oil Guy and the Oil Bible sites,

Motorcraft is Superior to Mobil 1..

The Following are specs of four of the most popular Filters for the Mustang, I decided to put them to the test

(The benefit being oil doesn't wash over the outer dirty oil/silk in the media on the inlet side when in the filter is in bypass keeping a cleaner flow of oil) By far one of the best filters under $14

Supercharged99

great info!

Supercharged99

where can i pick up the group one filters? ive already put a filter on from the group 4 the oil in using is to expensive to change again so ill have to be easy on it till nextg oil change

ShadyNinja

If you are talking about "All Out Contaminate Removal"
I would rank the Royal Purple just below the Amsoil oil filter

Royal Purple Oil Filter

with 99% filtration efficiency at 25 microns.


Amsoil Oil Filter

EaO Filters provide a filtering efficiency in accordance with industry standard ISO 4548-12 of 98.7 percent at 15 microns

Data copied and pasted from each company's website.

its splitting hairs but just thought you should know.

The AMSOIL EaO11 oil filter is by far the most advanced oil filter ever manufactured in the world, hands down. The state of the art patented nano-fiber synthetic media is able to filter down to 15 microns yet still flow as well as the best of them. This is one filter that can take any crap out of your oil and still flow as much than the most free flowing filters on the market.

I won't use anything else.

Arguing that an SL oil with ZDDP is better than SM/SN oil is like arguing that fiberglass is superior to carbon fiber because it contains "real glass". ZDDP certainly works, but it's pretty much obsolete except for a few engine designs that are also obsolete. Modern anti-wear and anti-oxidant additives are organic and have no metallic signatures. The absence of zinc and phosporus in an engine oil doesn't signify "weak", it signifies "upgraded".

Then there's the UOA issue. Metal readings in used oil analyses are meaningless unless they're over 100ppm. A UOA tells you the condition of the oil, not the engine.

And, while I'm being controversial, Group IV oil formulations are not superior to Group III formulations, except for (again) a few cases. The main difference between Gr IV and Gr III is oxidative stability. The "dirty little secret" of Gr IV basestocks is that they don't dissolve additives properly, making it necessary to blend in a shot Gr I or Gr 2 (low-end-conventional) basestock so the additives will stay dissolved. Gr IV with Gr II blended in is no more "pure" than a Gr III.

The special cases where Gr IV is superior to Gr III are the Gr IV/V blends that are pure racing oils. They're not recommended (by any of the manufacturers that make them including Redline) for use on the street. They do have superior film strength and they don't shear under heavy load, but they're not a solution for your daily driver.

Ummm, yeah....try convincing that to someone who has SEEN first person what the new Mobil 1 API SM formulation are doing to the camshafts in a "modern" 3V Ford modular engine. Try to convince those who switched back to an API SL formulation noticed decreased ppm of wear metals in their UOAs. Try convincing AMSOIL, Red Line, and Royal Purple of this also.

Your argument is laughable to say the least. The new "replacement" additives are FAIL, and if they weren't, the aforementioned companies would have jumped on the bandwagon and began using the "upgraded" additive you hold so highly. Seriously, stop reading things at BITOG and believing that everything over there is fact, and that everyone who posts there are experts.

So you are saying, a normal UOA that shows 10 ppm content of any wear metal, then they change formulations, and the next UOA shows the same content @ 80 ppm. In your logic, I shouldn't be concerned about it because it's less than 100 ppm. You say it's the condition of the oil? REALLY? Was the oil formulated with iron, copper, and aluminum? Trust me, the condition of the oil when wear metals are concerned is DEFINITELY an engine concern.

WOW! Can I have some of the drugs you pour into the kool aid you are drinking?

OK genius, I've heard this one too, and even if a group III oil is superior in the solubility attributes, then how do you explain a group IV trapping just as much contamination in the oil filter. That's right, the oil pressure and movement of the fluid itself push the contaminates to the filter. Seriously, I've seen engines torn down using NO group III base stock (only group IV) and there were less particles found than your average group III. This is still a debated topic, and primarily driven by those who profit from the sale of hydrocracked petroleum. *cough* Pennzoil Ultra *cough*

The only major differences from race oil to street oil is the additive package (when AMSOIL is concerned).

I'm really rolling my eyes at you this time. Go back to BITOG and dig up more BS to call fact.

Hey JAJ happy 10th post and welcome to MF troll

cliffyk

Factual and well put forth--here's a real welcome to the forum!

-cliff-

A tip though: Don't waste your time trying to sway the faithful (of any denomination) with facts and hard evidence--it just labels you as a non-believer and infidel--and has no effect upon their faith.
