Endurance and Titanium both disappearing-- now what, Fram?

[Hohn]

I don't know of anyone really offering the mass market anything approaching the premium synthetic media of these higher end Frams.

Wix XP is synthetic, but not on the same class for efficiency. Purolator we'll just say is also not in the same class.

We have efficient media available in the good filters from PGI, Pentius, etc. But because they are a blend at best, the efficiency comes with a flow penalty. There's no just media that competes with entirely synthetic nanofiber that can match the efficiency and flow combination.


Who's left to carry the premium media torch for PCMO applications? Are we just left with unbacked Ultras and little else?

Wake up Fram!

What about Bosch or STP? They aren't discussed much on here. I've used Bosch many a time.

I’m not aware of the Titanium going anywhere. AAP exclusive.

Any insight as to why the Endurance is disappearing?

Can you furnish links to this information?

Thread 'My Walmart has dropped the Endurance for a new 20k Purolator'

Mar 23, 2025

Over the last 4-5 months I’ve been reporting here that the Endurance shelf at my local Walmart has been shrinking. Today it was totally gone and replaced with a new 20k mile Purolator. I’m guessing it’s a new Walmart exclusive.

You can't conclude that without an actual dP vs flow test. Back when the PureOne (a blended media) was in the yellow can, it had high efficiency and a very good dP vs flow curve, which was tested and supplied by Purolator back before M+H got hold of them where the engineers would actually answer questions and give data.

Ah. Well that makes more sense. But that doesn't necessarily mean that they are discontinuing the line entirely. Fram might contract with Amazon or someone else to exclusively sell the Endurance. Or not make it exclusive to anyone.

I do enjoy that there is no micron rating on the Purolator box

You do realize that the new versions of the Ultra and Titanium don't have full synthetic media anymore - except if you can find an OG version. Only the Endurance is full synthetic.

 

[ZeeOSix]

Speaking of dP vs flow ... I'd like to see BR do their dP vs flow test on some PGI made extended life version filters. That's about the only source you're going to get any comparison info unless you want to setup your own test rig. BR ... are you reading this?

Probably low sales, since it was only sold a Walmart and it's a higher priced filter compared to all the others Walmart sells. Maybe too much "box swapping" too, lol.

Synthetic media does tend to have less restriction for a given amount of media area and a given media pore size, but the Fram Endurance and Purolator Boss use less filter media than a quality cellulose/synthetic blend filter.

While the Endurance uses full synthetic media, it doesn't have much media and the media has a small pore size. The efficiency of these filters is very good, but their restriction is not very low, and their holding capacity is also not very high. Purolator took a different approach and used a more porous media (and typically a bit more of it), which results in poor efficiency but also low restriction and a high holding capacity.

Filters with cellulose or synthetic blend media can perform just as well or better than those with synthetic media. It just requires more media to achieve the same balance of efficiency, restriction, and holding capacity. Quality synthetic blend filters like the Pentius XL do use a lot more filter media than the Endurance or BOSS.

meh, buy 5 now.. and worry about it in a couple years when it still isnt an issue.

 

[Glenda W.]

Or buy the Amsoil or Royal Purple oil filters which are the same as the Endurance. All made by Champ Labs.

Higher "holding capacity" because it takes way more debris to to clog the open pores to get the dP to rise high enough to stop the ISO test. In the meantime, lots of debris getting past the media, and lots of already captured debris being sloughed off from the rising dP, resulting in the low efficiency.

Exactly ... same guts, different can. Even still get the ruffled leaf spring.

I didn’t, thanks for the information.

Fram has soured me so bad I question using my old OG Ultras.
Maybe I'll paint them green

Quality synthetic blend filters like the Pentius XL do use a lot more filter media than the Endurance or BOSS.

These days I’m inclined towards the Pentius approach. Use a cost effective media you can source consistently and process effectively, then stuff as much as you reasonably can inside the shell.

While I lament the loss of OG ultra, I’d be perfectly happy to run a Pentius UFXL or PGI premium forever.

I don’t need much holding capacity because I’m not trying to get filter cost below 0.0043 cents per mile., I just want the filter to make it 5k with superior efficiency and the lowest practical delta P.
