Just some observations on this thread. Again confirmed with the posted Fleetguard paper that UOA's do NOT prove the efficacy/efficiency of an oil filter. Plus Blackstone has said in an email posted here, they see no difference in results between high end/efficient and low end filters. Yet, I see 'some' of those referenced here as filters not being a critical factor using UOA's to prove/defend their position. Fact is there is no correlation between UOA results and oil filter efficiency. Thst said, I'm sure the same folks, some who post as authoritative, will continue to point to UOA's as evidence of oil filter's insignificance. Add to that the cost of regular UOA trending makes the ROI very dubious, imo.

Also noticed that while some claim the benefits of an efficient oil filter vs one relatively inefficient to be insignificant and/or unmeasureable, they themselves tend use and prefer efficient and/or high end filters. I've read many posts about using this filter or that because of it's high end efficiency. And in some cases that means using the newest synthetic filters. Why is that? Because what is there to lose? Nothing. What is to be gained, well without multiple teardowns under very controlled conditions, difficult to say. But, intuitively there must something gained or why not just go with the cheapest oil filtration for the cheapest price.

Lastly, while synthetic filters use less media area to accomplish high end filtration and capacity, those factors are not limited to synthetic filters. The Bosch Distance Plus uses a synthetic cellulose blend and has a rated holding capacity of ~29 grams. I have run the D3323 two oci's on a 3.0L Honda and wouldn't hesitate to do so again. The BD+ rated capacity matches or exceeds the highest end synthetic filters with a 99.9% rated efficency, but as is Bosch practice no micron level is listed.

If my memory is correct, weren't there some threads in the UOA section that did show some correlation in the larger particle range that more efficient oil filters kept the oil freer of those larger particles? I'd have to go digging around for the data.

With the Fleetgaurd test, even though the most efficient filter used was 99% efficient at 10 microns, it's possible it still didn't filter out 3 micron or less particles any better than the other less efficient filters in the test. I just don't see the value in measuring only particles that are 3 microns or less in a test like this.
 
^^^Zee you could well be correct. There may have been particle counts as opposed to strict UOA's but I'm not sure. My point was that many times posters come here and say my UOA shows no difference or insignificant difference between high efficiency and low efficiency filter use. Saw a recent UOA using only the Honda OEM purported to show that filter efficency is insignificant. I just don't see UOA's being a valid test of filter efficiency or effectiveness. Among other things besides particle size measured there's just too many uncontrolled variables.

Bottom line, in pc use with flow considerations being insignificant, my preference is generally for something more efficient than less so.

Here's a write-up by our own dnewton3 on how Blackstone does a UOA. Nice write-up.

Near the end of the article is says:
"Blackstone does offer a particle count analysis, but few BITOGers utilize that process. PC can be done from 2um to 100um. There are two types of PC methods; pore-blocking and laser. With pore blocking, a calibrated micro-screen of known sized holes is used to process the lube. With laser, the energy beam is sent into the fluid. Ryan mentions that they prefer the pore-blocking method because it is not susceptible to entrained air or water, unlike the laser method. The sample is sent through the pore-screen at 60psi, and then analyzed for the quantity of particles trapped by the screen. The “normal” screen is 15um, but they have other sizes."

I'd like to see the data in that particle range for different oil filers on the same engine with the same oil ran under the same mileage and conditions. I know I've seen some data like this on some of the UOAs posted on this board.

I didn't see it mentioned in the article above, but when Blackstone measured xxx PPM of iron for instance in the oil, at what particle size are they measuring? I'm thinking it's something way down there like 3 microns again ... true?
 
Yes particle counts are something offered by B/S in addition to/beyond the standard UOA, the latter of which I was referencing in my previous posts. Many just offer up the common standard UOA (no particle count included) as evidence one way or the other regarding oil filter efficacy.

I will post the link below to the thread where B/S says there's no difference in insolubles between filter brands. In a 'standard' UOA (no particle counts) insolubles is what is generally referenced for wear.

Now particle counts is another subject beyond the standard UOA to which I was referring. I'll not get into them. Just that saying the standard UOA shows some evidence regarding filter effectiveness is not valid/reliable.

Blackstone says oil filter brand doesn't matter.

Read the link and other associated links about the Blackstone UOA testing and their comments. Blackstone did specifically say in the header of the UOA report: "low silicone and insoluables indicate proper air and oil filtration".

And they also said in email traffic: "Theoretically, switching to a better oil filter would reduce insolubles."

Guess it also depends on what the size is of these insolubles are. Most of them are probably well below what even a good high efficiency oil filter can catch anyway.

Who knows, maybe he had one of those PL14459s with the blown out media. I guess it would pay to cut open the oil filter and look at it anytime a UOA is performed to make sure the filter was actually OK during that OCI the UOA is for.

From this B/S email they see no significant difference in insolubles which is what is tested in a 'standard' UOA, between 'any' oil filter not just the OP's of that thread. So, no correlation in obtaining "proper" oil filtration and use of any specific filter, high vs low(er) efficiency filters.

"Theoretically" I might agree with them depending on the size of the insoluables, however as B/S stated standard UOA's haven't confirmed/proved that theory.

To my knowledge, Purolator doesn't rate the capacity of every filter. They give a representative part number (30001 series) and use that as a comparison. The PL14459 very well may have a different capacity than the PL14610, but we wouldn't know it because Purolator doesn't list the capacity for each part number.

Few on here acknowledge the possibility that Purolator may be using different medias in different part numbers to closer mimick the specifications and behavior of the actual OES filter.

Yes, the media types are different, but I think it's key to recognize that even with the synthetic media, Purolator had to give up some efficiency to realize the capacity they were looking for.

Yes, I saw the "continues" part in Blackstone's statement. Could be that the insolubles are way too small for even "high efficiency" (ie, A PureOne at 99.9% @ 20 microns) to make any noticeable difference in the measured the insolubles.

Only thing that's not clear in the B/S insolubles comments is that they really don't clarify how they are determining if filters on the market make a difference or not. In order to do that, someone would have to send in UOAs with all variables being the same except the oil filter being used, and look at the measured insolubles to see what effect just the oil filter has. I doubt any one B/S customer has really been that regimental to give B/S enough data to make a conclusion for sure. Unless B/S has done it's own controlled test to determine the effect of filter efficiency on insoluble levels, they only have customer oil samples to do by.

Yes, Purolator uses the 30001 as it's reference point for the efficiency and most likely the holding capacity (they say 13 grams for the PureOne on their website). So that means if say the 14459 has half the media surface area, then one could say the holding capacity is scalable and is only 6.5 grams for the 14459 for example.

I doubt that Purolator is doing that - why make 4 spin-ons a different design than the rest of the filter line? I think when they design an oil filter they make sure it can flow well enough without excessive media delta-P to meet the engine's oiling system specs (ie, oil pump volume output vs engine RPM), and give it a bypass setting that matches the filter's flow performance and engine oiling system parameters. If an oil filter is designed to flow and filter well, it will meet the specs of hundreds of applications, that's why one filter can be used on hundreds of different vehicles as seen in the filter application catalogs. Oil filters are not really that "matched" to any particular vehicle.

The example given in post #1 showing the comparison between the Honda OEM and the PureOne for the same vehicle shows that PureOne hasn't tried to match the flow vs PSID parameter of the Honda filter. Purolator has made a more efficient filter with a little more flow resistance (making the PSID slightly higher), but with a positive displacement oil pump that slight increase in PSID doesn't really matter.
 
Pointless to take this UOA discussion any further. I agree with Jim, the Fleetguard paper, and acknowledge the statement from B/S saying they don't see any difference in standard UOA analysis with respect insolubles (which is the measurement tested in standard UOA's), and oil filter used. Standard UOA's are not a valid/reliable test of oil filter efficacy. Until a scientific study or studies are published using 'standard' UOA's as posted here on Bitog showing a correlation with efficiency of filter used, I'll stand by that.

That said, my general preference like others here is for a filter with higher efficiency as opposed to lower.

One very important aspect is missing from above: filter change intervals. At least for the 14610 series, this filter can be expected to be on the car for up to 20,000 miles. Any of them, from the white can Classic to the blue can Synthetic. It can be expected because Honda recommends two OCIs for each filter, Hondas will sometimes go 10,000 miles on a MM OCI, and Honda is the predominant application for the 14610.

Recall that Purolator's warranty states very specifically that the limited warranty period is "the number of miles and driving severity published in the owner's vehicle manual as the recommended service interval for filter replacements."

http://www.purolatorautofilters.net/document/Documents/PuroLimitedWarranty.pdf

Purolator has a very compelling reason to ensure that even its white can Classic stands a chance of 20,000 miles in an engine.

I wouldn't be so quick to write-off all Classic filters as equal, or all PureONE filters as equal. I'm not saying that the 14610 is *designed* differently from others, but I am saying that it'd be very easy in a mass production environment to use a slightly different media in some filters than in others, even in the same line (Classic, PureONE, Synthetic, etc).

Mine is as well. My point is not to advocate for less efficient filters, or to promote their use.
 
Yeah, it's one of those 'round and round' discussions. I'm not totally convinced that these tests were done in a way that gives the whole story. They are always looking at particles much smaller in size than the filters they are using can effectively filter too, so seems like the data is non correlating to some degree. Would be nice to see a test that does a much larger range of particle size, but we have already seen some of those tests (GM and Amsoil particle size vs. wear) and the results were that better filters do keep more wear particles out of the oil.

So like you, the conclusion for me it to use high efficiency oil filters because it "can't hurt" to do so.

So based on that logic, there are probably other Honda vehicles that could go 20K on an oil filter based on the OLM and a filter change every other oil change. If so, which Honda vehicles don't use the PL14610, but rather a PureOne that is rated at the higher efficiency level of 99.9% @ 20 microns? If there are some, then obviously Purolator hasn't designed the PL14610 around Honda's potentially long filter change interval of upto 20K miles.

There may be Hondas that use something besides the 14610 series. If there are Hondas that use a different series, it's probably safe to say that Honda is not the predominant application for that series of filter, and Purolator is probably specifying a media for each part number that is most closely matched to the more popular applications of that particular part number. In this world of multi-use part numbers in the aftermarket, you're not going to be able to nail the OES specs exactly for every single application. You pick a good compromise, test it, and go with it.
