Fram Endurance Flashlight Test in canister

True, but that was a rectangle with a much, much smaller aspect ratio than the narrow slot. The flow characteristics of a narrow slot are different a generic rectangle.

Looks like very clean construction including the spring where it fits very smooth end caps …

Like I asked before ... show what the discharge coefficient for that would be. Show some proof and not an assumption of what it would be for that configuration. From my digging, one paper (I showed you which one) even found through testing that long narrow rectangular orifices had a larger discharge coefficient than a round orifice of the same flow area. Maybe when the aspect ratio gets to a certain point it behaves differently than expected. Even if the discharge coefficient was around 0.25 (doubt it's that low), it would still calculate out to 8-10% of the total flow going through the oil filter in the example used for the model.

That Ultra looks ratty ... even the media looks like some recycled old house insulation or something.

If I was to think of theories, it would be Crowne bought First Brands in March. This was made after that. A counterfeit wouldn’t install mesh like this. It is sold by Amazon not a third party. It is sold by the Fram Store, the company itself. The media was fine before I handled it, nothing wrong with it. I can see it is two ply, put a bright light behind cut piece, no holes sparkling. Looks like excellent media. It may well be the best media on the market given it’s rating. My theory on having the mesh is this filter model is commonly used for v8 engines that run hard like trucks and suvs and they don’t want the media to fail. More cut opens of other models recently made will tell more.

To me , here’s where I stand on the topic : I like the grip end of the Fram oil filters (easy on /easy off by hand ) and want great filtering and great flow through . I’ve been using the Fram Ultra #9688 from WM for up to two 5K OCI’s and thought to move up to the Fram Endurance - but now not so sure the move up to the Endurance filter over the Ultra is worth it for the supposed better filtering and flow through rate over the Fram Ultra - which would you choose based on above ?
If this is the new Fram quality I’m out on every model not just the Endurance. The xg2 C&P’s I’ve seen here on bitog look great compared to this.
$4.85 on amazon seems suspect to me. Guess we’ll have to keep an eye open for other c&p’s to see if this quality continues.That Ultra looks ratty ... even the media looks like some recycled old house insulation or something.
I have that exact filter on my Hyundai right now, but it’s Endurance. Advantage over current Ultra is 1) Wire backed 2) superior 100% synthetic media.
Both probably have same “bypass leak”discussed here.
OG XG2 also has 36 pleats.
I suspect center tube is same diameter (will check when I received my OG XG2s).
So Fram did not increase the surface area on the XG2. Yours is the second that shows super wide pleats at the crimp on the new XG2.

No filter maker is going to increase media surface area. Seen many decrease it ... media "shrinkflation" so to speak.
That OG Ultra in the link with the super wide pleats near the seam is 10 times worse than the one in this thread. That one in link is crazy wide, but was also wire-backed media.

The filter I bought XG2 is direct from Fram the manufacturer on Amazon. Hope to see more samples and versions, not in a hurry.
What I was getting at is that Fram said the new XG would have more media surface area in order to provide the same holding capacity.
In the case of the XG2, it does not appear to.
(I will confirm in a few days when I get OG XG2 or @Fair enough can measure his dissected new XG2 - WCW got 148sqin on the OG XG2).
In the case of the XG10575, WCW confirms that Fram did increase surface area from OG to new style by 50%!

What makes you say that the one in the link (cut open in 2023 after 5000 miles) is an OG XG2? The pleat thickness?
It's wire backed at least, per the OP of the thread if you read down the thread - post 16. Are Ultras with the new media still wire-backed of the new media doesn't require wire backing?
That's true ... they had to increase the media area to make it perform equal to the OG Ultra.
I was talking about media area increasing without any design change to the media. I have never seen that happen, and doubt it would happen. I have however seen media area shrink by quite a bit with the same media ... probably a "shrinkflation" cost cutting move.
Here is a good reference point. A FS2 / XG2 made in 2022 (apparently). It is wire backed but that doesn't make it an OG. Only if we see pink media is it OG.
But also something that makes an OG more likely to perform is if it has the non metal seal between the end plate and the leaf spring. Is it there on this one?
