Amsoil is usually very open with specs but I can't seem to find the Beta Ratioa or even nominal micron ratings for the EaO filters. I'm just looking for a general idea on how efficient these filters are versus the other brands for which such specs are available. Have they been published somewhere?
Amsoil EaO Beta Ratios

Amsoil oil filters are still 75% efficient at 10 microns.
so far, all I have gotten auto-non-responses to my Beta Queries. Giving us one Beta does not tell us much, and is suspicious in any case. Several SAE papers point out that size, depth, fold, construction all contribute to the filtration efficiency. On the WIX site, the filters, especially in the under 15 micron range, have slightly different Beta Ratios, despite the fact that the construction is identical, leaving only scaling factors caused by the size limits.
What did the Amsoil guy tell you when you talked to him?
no reply to voice mail,
sent e-mail with full explanation, but it has not been quite 24 hours, so to be fair, I am not complaining about the response to this e-mail.
(It has been ~9 and ~5 days since I sent the same question in using the web site help site...and I am complaining!)

Where did you get that datum point? Amsoil refuses to confirm/deny when I ask.

ISO 4548-12 is a widely accepted industry standard.
The EaO ad states: in accordance with industry standard ISO 4548-12 of 98.7 percent at 15 microns,
That's beta15=75 to me
Here's a Donaldson comment on the ISO multipass test:
Testing Standard
The ISO 4548/12 multi-pass test is a widely accepted industry standard test used by OEMs for the purpose of evaluating and comparing the efficiency and capacity of liquid filtration products.

I have had no issues with the Amsoil claim of EaO ISO 4548-12 15 microns, 98.7 efficiency (Beta 75). This datum has already been entered into my data analysis.
It is. I'm not at all sure why the stats aren't published - I am guessing it has something to do with an agreement with the media manufacturer. The best I could get was the name and phone # for 63Avanti to speak with. They certainly wouldn't tell me jack - so it must be proprietary.
I read that figure somewhere, I should start a folder of printouts instead of just remembering what was said. That figure of 75% at 10 microns doesn't sound too far out of the way, given that the EaO is 98.7% efficient at 15 microns.

well, I have the name of the filter manufacturer, and the media vendor, and the Betas for all of the media that media vendor sells. If I could match up the finished product with the media, I could give a reasonable cut on the beta from 2 microns to 40. Would not that be a hoot!
A hoot indeed - which one comes closest to the 10 and 15 micron numbers......
When ever i have sent a Q in it's taken DAY'S to get a
response back.
response back.

Assuming that they used off the shelf Donaldson media, this would work out to SYNTEQ 3 or 4
Efficiency Beta 2 (Micron): 4
Efficiency Beta 20 (Micron): 12
Efficiency Beta 75 (Micron): 15
Application Note: SYNTEQ Media # 3
Efficiency Beta 2 (Micron): 4
Efficiency Beta 20 (Micron): 12
Efficiency Beta 75 (Micron): 15
Application Note: SYNTEQ Media # 3
A little off the question, but Terry indicated a while back that the Eao beta ratio improved as the mileage increased. IF this is the case, as the media fills up during the service interval of the oil, the ratio improves. What was found (or how I took it) was the ratio improved, and the flow was not hampered because of the media design.
wrong Terry....
welll, I could come up with much worse Betas if I were to "take another donaldson off the shelf."
I assume you have the same or better background in tribology than Terry does to refute his claim? I'll take his statement as truth long before I'll take yours.
