Seems like the Purolator Classic is best, $4$.

According to these studies: http://filtrationcomparisons.weebly.com/test-pictures-and-results.html

http://www.gmtruckcentral.com/articles/oilfilterstudy.html

http://minimopar.knizefamily.net/oilfilters/index.html

According to these resources, the Purolator Classic flows amongst the best (without being the absolute best) and it filters very well, it's above-average in filtration actually. For someone like me who wants good filtering without much of a compromise in flow rate, this filter is the best choice. It's a bonus that this filter is also among the cheapest. In fact, I think I prefer the Classic over PureOne which has the disadvantage of not being as free-flowing and the tiny paint specks worry me too (admittedly, I am probably being paranoid.)

Is my assessment mostly right?
 
Kind of except that the flow rate difference pretty much doesn't matter, so go with the PureOne.

If you don't like the paint finish, the Bosch Premium is identical (except the gasket is lubricated nitrile instead of silicone)
 
First link is by a member river_rat, and pretty much accepted here as an excellent evaluation of oil filters.

Second link with the exception of the pics has been panned because the same filters like Napa Gold and Wix and several others that are the same, show very different results. And the Puro Classic shows better patch test results than the Pure One. I'll believe the manufacturers specs over a patch test. Other examples of the premium oil filter showing worse results than the low end filter too. But, the pics are excellent.

Lastly, the minimopar as mentioned is fairly dated now even though it has been updated some.

But yes, for $3.27 at Wally, the Puro Classic is imo a good value ~5k oci oil filter.

maybe they think the can looks pretty?

Average store customer: FRAM's marketing and shelf space is better.

Store customer who reads both boxes: FRAM's efficiency is 99% which is higher than P Classic

I've seen it several times while browsing the auto section at WM. Guy picks up the OCOD, wife picks up the Purolator and says "Why don't you get one of these, they're cheaper?" Guy says "Because the Fram filters are better".

I get the Motorcraft filters from WM, as they are Purolators but with a silicone ADBV, where the Purolator classic has a Nitrile ADBV and the Motorcraft filters are still cheaper than the OCOD.

I will second the notion that the Classic is an excellent value for a 5-7.5k oci. Most likely the best.

Power of marketing.
 
Puro Classics are tremendous bangs for the buck no doubt, but for pure value I still think Motorcrafts have them beat, 70 cents at Wally's gets you a thread end bypass and often a silicone ADBV to boot on the Motorcraft.

But Classics are cheaper and cover a wider range of applications.
 
Of the top of my head.

Motorcraft about 93%. Classic is 97%.

PureOne is 99.9% at 20 microns with a couple of models 99.9% at 40 microns.

My guess on this latter point is it's to do with surface area. I have some specialist HVAC airfilters that have different MERV ratings despite being identical in everything apart from L&W (depth and material is the same). The bigger one has a slightly higher MERV.

Yep, Motorcraft's are solid construction value fiters, and what you say is true especially now that, thanks to Amsoil's testing, we know they are ~94%@20um. The MC's that are for FoMoCo applications now all have thread end bypass and silicone adbv. There are a few MC's for non FoMoCo applications that are dome end bypass with nitrile adbv, but they are scarce now. In that case, just as well off going with a Classic than hunting the MC imo.

As mentioned though Classic's cover a wider range of applications, and still spec the true (larger) size filter app as opposed to the downsized/consolidations like the Puro 'made for'/commercial, Group7 and ProMotive and some others.
 
Yeah, If I was going to buy a bottom dollar filter, it would be a Classic most likely. It has better efficiency than the bottom dollar Fram and is cheaper. But I want to make it clear that fiber endcaps plays only a little role in my choice. Of course I'm probably never going to use a bottom dollar filter again, at least on anything I truly care about.

RE Classic over Motorcraft... I lean MC. I wish the MC's had the same 97% @ 20 um of the Classic but the main choice point for the MC is the silicon ADBV. I've been convinced by the industry people I've had occasion to discuss this with that the location of the bypass is of only minor importance. The base end bypass is "nice to have" but my sources also expressed some reservations on the design of the current valves, as some did with the combo bypass/ ADBVs that are starting to appear now, both of which adds a point on the "against" side. I wouldn't be afraid to use an MC in a moderately long OCI, where I would hesitate with a classic due to a higher potential for ADBV issues (of course it would depend on the vehicle too... in some the ADBV is not a biggie due to the location of the filter.
 
If you "need" a silicone ADBV, for example my Jeep 4.0 application (sideways), or even my brother's old Tercel (sideways, eats nitrile ADBVs due to engine heat[?])-the MC, for the price, pretty much can't be beat-if you can find one that can be used on your non-Ford vehicle.

Negative. Quaker State filters at Menards on sale for $1.99 are the best! Same thing, different packaging!

Even sweeter when you get it on their 11% off MIR deal. Then they are $1.77!
 
For the MC FL820s and Purolator equivalents is this true?

FL820S: Silicone ADBV & Silicone Gasket. Thread end bypass. 94% efficiency at 20 microns.

Classic: Nitrile ADBV & Nitrile Gasket. Dome end bypass. 97% efficiency at 20 microns.

PureOne: Silicone ADBV & Silicone Gasket. Dome end bypass. 99.9% efficiency at 20 microns.

Bosch Premium: Silicone ADBV & Nitrile Gasket. Dome end bypass. 99.9% efficiency at 20 microns.

Ehh, not exactly. The QS OF, when an efficiency rating is found, is said to be in the lower 90's as opposed to Classic's 97.5% @20um for most. Also, unlike the Puro Classic many of the QS filter apps are consolidated and downsized to the smaller/smallest size. Example, the common 14610/7317 size is downsized to the smaller 14612. The same may even be true of the larger 14459, it is true for other 'made fors' ProMotive and Group7. Not saying QS isn't a good value filter where available, just not exactly the same as the Puro Classic.
