Bottom line is not all oil filters will become more efficiency with use.

And THAT more reasonable less expansive comment is supportable.

The general rule is that as large particles aggregate on the media, the filter media traps smaller and smaller particles becoming more efficient until the filter bypasses.

But there are some extraordinary circumstances where that does not happen.

 

[Simon_G]

Exactly where do the authors of that M+H paper say "normal filter behavior is increased efficiency with use".

Exactly where do the authors of your cited paper say "increasing efficiency with use is abnormal filter media behaviour"?

 

[Simon_G]

Lots of filter info sites parrot misconceptions over and over.

Your disagreement with industry experts does not render their statements "misconceptions".

Simon_G, Arthur E and Bob Arnzen should all consolidate into one user name.

If they aren't already.

Not exactly a compelling argument when one person creates multiple BITOG accounts, makes the same point under multiple usernames, and then “likes” their own alter-ego posts. It’s sad, and, it’s prohibited.

Folks, if you’re reading this, let me be crystal clear: multiple usernames for one person will result in a permanent ban.

A permanent ban.

 

[ZeeOSix]

Since only one person - you - disputes it, it is not a surprise the filter websites are not rife with citations to data.

Go find all the links to testing that shows all oil filters get more efficient with use ... I'm still waiting for some actual test data like the M+H paper shows.

Of course "it's possible" that some oil filters will get more efficient with use ... but show me the test data that proves it.

And THAT more reasonable less expansive comment is supportable.

That's what I've always said in this discussiion, and you're now just realizing it? Reading comprehensiion needs some work.

The general rule is that as large particles aggregate on the media, the filter media traps smaller and smaller particles becoming more efficient until the filter bypasses.

But there are some extraordinary circumstances where that does not happen.

Still waiting for the white paper and test data showing this claim.

Strawman response skirting my question. Go read the paper again.

I'm sure M+H doesn't know anything about oil filters, and therefore their paper presented at the Filtec Proceedings was all just a joke.

Zee - You’re free to post, of course, but the poster with whom you’re disagreeing has multiple personalities, and has been banned...

The paper says precisely what it states.

One person with two accounts needs to get a life … This kind of stuff is unbelievable …

The paper says precisely what it states.

Yes, it says that not all oil filters gain efficiency with use.

 

[ZeeOSix]

Even many decades ago they discovered that oil filters don't always gain efficiency as the media loads up. Don't know why it's such a stretch to see that increased delta-p across the media can make some of the captured particles in the media break loose and go down stream again depending on the media design.

Full synthetic oil filter media always seems to rate pretty high in the ISO efficiency test, so based on the fact that the ISO efficiency is the average over the entire test period, it says that full synthetic media is much better at retaining captured particles as the filter loads up and the delta-p increases.

 

[Arthur E]

Yes, it says that not all oil filters gain efficiency with use.

No one has argue with that.

What it does not say is that in general oil filters do not gain efficiency with use, which they do.

What it is not is a study of hundreds of oil filters in which the majority do not gain efficiency with use.

Still waiting for those white paper link showing that claim. I've searched and can't find them ... maybe you can (?). Even decades ago, tests showed that oil filters could lose efficiency with use.

LOL just like your washer gains efficiency when you have ring around the collar?

 

[Arthur E]

So far you provided a computer simulation which you misinterpreted and a segment of an unpublished not peer-reviewed paper marked "Not For Dist(ribution)" from an unknown source on cake filtration.

On the other side we have the filter companies and their engineers.

There is nothing to refute.

Figure 1 in the M+H paper was not a "simulation", it was measured efficiency data.

Still waiting for your links to back up your claims besides general words on a website from filter companies.

 

[ZeeOSix]

Here's another snip-it for you. I can find all this info saying oil filters can decrease efficiency performance from delta-p, but you can't find one soruce that shows data of oil filters getting more efficient as they load up.
