Oil will travel through the least restrictive areas first. Oil will travel through the tightest packed media with ease. Think how the oil passes through the main and rod bearings.
True, maybe calling media between the holes "essentially useless" is a bit harsh.quote:

You're right. The grid inside the center area of the element is the nylon "cage".quote:

Aren't we looking at the actual plastic supporting grid, not stripes on the bare media ?
Yea, I think I got the numbers right, here is the initial post:quote:

An M1 filter run about 5,000 miles reported:
>2 microns = 757
>5 microns = 280
>10 microns = 77
>15 microns = 30
>25 microns = 7
>50 microns = 0
The "stripes" are a bit lighting effect but still there as far as the actually element is concerned.quote:

Filter Guy: Actually, the "clean stripes" I am talking about are the faint outlines on the outside of the media. (See your first photo or Gary's second)
Are these areas where less dirt is embedded in the media or is it purely a lighting effect where the cage structure is visible through the media?
How did the ADB/Bypass hold up by the way? Any pictures there?
The point of this thread was to show actual testing on a used element. Have you seen that before?quote:

The title is "My E-core filter report, with pics" so I figured that you wanted to share your E-core experience. However, it looks like it is a defend Champ thread.
You really are a sad case.quote:

Cut open about 100 more of those E-cores and you will get a better sample pool. One filter is not really a good "test". Then you will see the end seam pleat flopping loose from the endcaps or pushed up flat against the center cage. Sure they probably last 3K miles, but not much more, believe me, so it is doubtful anyone here will see a failure. THESE FILTERS WILL NOT LAST CONSISTENTLY WITH THE LONGER DRAIN INTERVALS OF MANY AUTO MANUFACTURERS. I have cut enough open before we switched away from them to know.
BTW, My letter to the editor of Lubes N' Greases magazine, concerning oil filter quality and lack of required specs. will be published in their October issue. If I have time I will scan a copy of Tom Glenn's article concerning oil filters from last months issue and post it up here.
For those interested we are still using the Napa (Wix built) filters at the shop, and have seen no problems with them. About the only thing we have come across is a few that the threads are mis-cut on but we have run into this with all the different filters we have used over the years. We go through over 12,000 a year, so are bound to see a few flaws. We mostly use the ProSelect line, but use the Golds for certain apps. that are only available in Napa Gold. Many of the ProSelects have threaded end bypasses and all have a great media content, and high quality gasket. We have seen none with media ruptures, and the ADBV's work great.
I have seen several of the early release e-cores with the harder gaskets coming into the shop with leaks around the filter gasket, some have been pretty substantial.
