I'm not having any luck finding bypass pressure specs for the EaO filters. I'm asking because I have found that 2 very large, well-known brands of oil filter have noticeably different bypass pressure specs for some of the filter cross-references I use. Is there any info available for the Amsoil EaOs? Specifically, I'm wondering about bypass pressures for the EaO57 and EaO42. Thanks!
Amsoil EaO bypass pressure specs?

AMSOIL has chosen not to publish these specs.
Both filter ByPass valves are set to allow flow at 8-10 psid differential pressure.
Fellows - it isn't like HQ won't tell you when you ask
Yes, bulwinkl - that's what I would do.

I have a spreadsheet that I got from Amsoil that listed all of the technical data on their EaO filters. I could not find a way to post the Excel file, or a PDF printout, so I exported to a comma delimited text file and cut & pasted below. You can in turn cut & paste to a .TXT or .CSV file and import or open that in your spreadsheet of choice.
As Pablo states, if you ask Amsoil, they will tell you. I was told that they will be publishing the specs soon. They will also be publishing the specs and flow curves for the EaA air filters too. Its taking their literature department awhile to catch up with all of the new product introductions.
Yes bulwnkl, I too have found differing ranges of specs for different manufacturers filters. They almost always bracket the OEM recommendations, but I always want to know. Which is why I asked Amsoil to begin with too.

Great info, st, thanks!
Herein lies my 'issue:' The OEM-size filter for my application is the 57, which shows an 8-11 psi bypass pressure. The alternate, larger size I would use from Amsoil is the 42, which bypasses at 8 psi. As far as I can tell, the actual OEM bypass pressure range for my filter need is somewhere between 12 - 17 psi, and perhaps 14 - 16 psi is a more accurate range.
Sorting the data out, I see that all their EaO filters with 3/4 x 16 threads bypass between 7 and 11 psi EXCEPT the EaO41. It bypasses at 16 psi. I think that the gasket diameters are close enough, though it may actually be a smaller filter than OEM-size (and I prefer to use an oversize filter).
So, what do you all think? Is it preferable to use the filter with the bypass pressure that I believe to be closest to OEM, or to use a larger-size filter with a much lower bypass pressure?
Thanks again for the great info, st!

I wouldn't worry about it ..myself. The only time I would be picky is if I owned an Audi/VW where they have distinctly higher bypass pressures. This they obviously do for some purpose. There are very few instances where a bypass opens. In my observations, I doubt that you would ever see it from loading a filter by leaving it in long enough. The other situations are way too infrequent or short in duration to be concerned about.
Again, just my opinion.

Good compilation (Thanks!) - I'm not sure where/when your data came from st, but the 8-10 on both filters came from Amsoil Tech yesterday. I did hear that they will be publishing the list like the old days soon.
I certainly would have no fear of using a slightly lower psid, especiall if it were oversize and had a good flow nature filter.

Well, I've decided to run an off-spec oil this time (5W20 where 5W30 or 10W30 are specified), so I guess that since the EaO media is equally good across all the cans it's in (right?) I'll just run the bigger filter. The lower viscosity and the lower bypass pressure will (in my own mind at least) compensate for each other somewhat. Thanks, guys.
Bulwnkl,
If you have room, I'd use the Eao-96 or even the EAO-15. I've used the 96's on my Tacoma, which called for the 57 and I've used the 15's on my old Audi 100, which called for the 34.
This media has very low restriction and I don't see any problem with what you have in mind.

Not to be a pain, but my experience with the filters I use is that the "common" bypass pressure is identical for all of them from most filter manufacturers (8-11 psi across the board). However, it also appears to me that the actual specification may be somewhat different (higher) than that in the applications I use. Thus, my question. Thanks again, fellows.
I have a g35 which amsoil recommends to use the EA013 filter which is specified for 8-11 for bypass. I have been using the EA020 which is specified for 11-17 for bypass...
What danger I am putting my engine into by running the 20 vs the 13?

Actually, amsoil recommends the EA012 but I was using the 20. The 13 and the 12 look like they're the same, except the 13 is just larger than the 12. Still, is there any danger in running the 20 vs the 13 or 12?
TooSlick, what about the large bypass pressure differences of the 12 & 13 vs the 20...
8-11 & 11-17 are two very different pressure ratings

Hope this helps.
427 - That was really nice of you! Very cool.

427. Was that a cut and past from Excel to a graphics program? I just found out that could be done a couple of weeks ago. It's a handy feature.
