Fram Endurance - Keep or ditch?

The new Mobil 1 is not a PGI made filter. It's made under Highline Warren.
Just use them and move on with life......
Yes. I too have noticed differences in Delco PF63 filters I’ve used over the last 8 years for my 2017 GMC Sierra 5.3. I assume it’s like most any other item…there’s several sources producing products (lowest bid?) and each source has their own unique production process.
This thread has enlightened me to be aware of closed louvres etc.
I assume a closed up filter does no filtering as it just bypasses oil??
They are made by PGI. Warren is a distributor.
Got any info links showing this is true?
There is never any mention of PGI having any connection to HW and/or Mobil 1when searching for any connection.

There is a connection between "Prime Guard" and Highline Warren, but no connection between HW and "Premium Guard Inc" (PGI). Prime Guard and PGI are not connected, they are two separate companies.

My vote is for the Purolator..... Beautiful paint job! But they should have charged a buck or two more, and given it a clear coat on top of the blue metal flake. 
It's not only here, but if you look around the "interweb", Fram bashing seems to be as commonplace as chocolate sauce on Vanilla ice cream. Are there better filters out there? No doubt. But it does get a little old listening to all of the regurgitated nonsense of how terrible they are.
There are millions of them in use all over the world, and have been for well over half a century. And crankshafts aren't crashing through oil pans because of them.

Well an obviously old thread but I hope he didn’t dispose of those perfectly good filters. The louver openings on those were narrow at the top and got wider as you go down the spiral. I have since moved on to PGI filters but still have one Fram Endurance left, two Purolator 1s and a Boss (actually have about 5 small
Boss 14610s for my Nissan Titan which doesn’t get driven routinely anymore). I have never had a Boss or Purolator with completely closed louvers and **** sure plan to use and put 4k miles on every last one of them!
I use to see the same thing in louvered oil filters until I bore scoped one and realized it is a optical illusion of one's eyes as the louver openings appear more closed at the opening due to less angle to adjust looking at the filter with more angle to see better as you look towards the dome end.
Also in production vids I have seen of center tube stampings, it is one continuous cork screw of the punch out for the louvers and then cut to length.
