[Cut Open] Microgreen 301-1

Quote:
It's clear to me that during operation, the orange rubber valve would be deflected down against the main filter as oil flowed into the filter via the holes in the baseplate.

So, at least for this filter (bought between 1 and 2 years ago by the way), the anti-drainback valve looks like it's perfectly functional, and does not need to move the main filter any in order to work.


I used the clamp in order to make it easier for me to take the side picture. It wasn't real tight. Are you sure the adbv is on the inside of the baseplate? because the cut is on top? The neck on yours looks longer. Mine had no space for the valve to open.

That was 'goodtimes' actually.

Yep, that all looks like a normal configuration to me, and the ADBV should work fine. Don't know how old goodtime's MicroGreen filter was, but it seems like there might have been a design update at the ADBV area.

Yes, quite sure. I used a Dremel tool to grind the bottom outer edge off.

Oops, I forgot there is the space between the end cap and bypass plates. To counter, the space around the hole surely is 99%@10 microns efficiency. The posters filter looks fine.

 

[ZeeOSix]

^^^ Only if you have to beat that tube into the hole (tight press fit).

3rd party testing > your personal opinion.

Show us another spin on filter that has matched the MG's tested proven performance out to 30k.

Still waiting for ISO filter test data. No, some tests by Blackstone prove absolutely nothing, they are just anecdotes with no actual data value to understand the performance rating of the filter.

 

[kschachn]

What Blackstone testing exactly? Please don't say a particle count test.

Completely and totally correct.

The stuff some people on this board think "proves" something is really ridiculous.

They give blanket ISO spec on their website & claim 2

The tester- DBmaster and I already posted that on another thread and you know this.


Remember the rock catcher thread? Te thread where Nate and you said Bypass level filtration was "hogwash and couldn't have any effect on TBN - then you recanted and Nate went away after Z06 agreed with me.

Can you post a link to the results of their ISO-4548 test?

And yes the rock catcher thread where you were saying the filter itself could somehow retain TBN. I gave a scenario where by particle retention of soot it might help preserve TBN, but not necessarily for gasoline engines. That one?

What is the ISO spec on their website? I don't find it. List it here for all of us.

Bypass level filtration doesn't affect TBN in a gas engine. Still don't agree with that. Filtering out particles does not have an affect on the chemistry of acids/bases that directly change the TBN. Bypass level filtration on a diesel which may remove soot will help prevent the TBN from falling faster because soot can cause acid formation.

If you have a reference that bypass filtration affects TBN in a gas engine post it again. I must have missed it.

Dnewton talks about this at length in the bypass forum. let your fingers do some walking and read up about how it works.

They claim 2 micron filtering - thats their spec.

They claim a blanket ISO filtration spec 4548 on their site. not " - ". (we've gone over this)

http://www.microgreenfilter.com/microgreen_element_oil_filter


are you refuting DB masters blackstone tests?

If you guys don't like it thats one thing - but refuting 3rd party tests is an interesting stance.

Seems like you guys pick and choose which 3rd party claim verifications you like and those you don't.

The filter either performed as claimed or it didnt.

DB master put his money where his mouth is and demonstrated it did.

...any other filter do what he did?

I went to the link you gave and I can't find any results of their tests.

What exactly does "This includes testing under ISO protocol ISO-4548" mean? That ISO tests has multiple components, which one are they referring to? It could just be the pressure component, not the filtration. "Testing under ISO protocol" is an odd way of saying "Performed ISO-4548 and the results are..."

What is more interesting stance than refuting insufficient 3rd party tests is the indignation that's expressed when people are asked to back up statements they make.

 

[UncleDave]

Isn't blackstone testing the gold standard here?

Maybe its an odd way of saying but they make a claim of 2 micron filtering - and post blanket ISO #.

Maybe they are lying, maybe they are intentionally evasive because thy can be-

Im skeptical of all claims by manufacturers until verified by a 3rd party with a a known lab.

This filter passed the marketing claim test.

UD

 

[kschachn]

I could not care less what a "gold" standard is or is not. On the other hand, an industry standard (ISO, ASTM, etc.) test that produces repeatable results and - most importantly - results that can be compared to each other is critical. And this time it is you that know that too.

Their claims are worthless on that website and the "gold standard" Blackstone tests do nothing to make up for the deficiency.

Their - or anyones claims are all worthless.

The 3rd party testing isn't. (usually)

[kschachn]

That's completely untrue and backwards. Are you claiming that when Castrol says that their 0W-40 has LL-01 certification that is worthless? And that I should go by a Blackstone VOA instead?

Im saying I don't trust claims not verified by a third party.

anyone can say anything.

Oh, what the heck. I'll throw my 2¢ into the ring: I buy the Microgreen filters only when they're on sale and priced about the same as any quality filter. And, I change it with every oil change as dictated by the owners' manual or the OLM (whichever is applicable)

At best, I'm greatly reducing the wear in my engine by filtering anything over 2 microns out of the oil. At worst, I'm using a filter that I have to order online only when they're having a sale. It doesn't cost me anything more than I would be paying to use a different high-quality filter.
