Pentius UFXL PLXL7317 O-Ring gasket failure.

I bought a case of Pentius UXFL7317 recently. The first filter was put on 3k miles ago, and I was going to change the oil today, switching to HPL Premium Plus PCMO.

I had read the Pentius filters were currently unavailable, so tried finding some last week and was not able to find any for sale, except for a handful of individual filters on Amazon. The cases are unavailable. Makes me think they may have a manufacturing/part problem.

Now I wonder if I should go ahead and install another Pentius until we get more information or go buy what we know are currently "the good ones". What would you do?
 
Well, I called Pentius and spoke to Diego. He was very upfront with information he could share.

- This filter is only made in South Korea
- They have not had any failure complaints (certainly along these lines, anyway)
- I told him about this post on BITOG, and he pulled it up while we were talking, and is watching it (Hello Diego)
- He also has a Honda and uses this filter himself
- They have no shortage of these filters and are shipping, just not to Amazon at the moment, but will be again soon

I am going to do a very careful inspection of the filter I've already pulled from the case, and if all looks good, use it. Maybe not with the full confidence I had a couple of hours ago, but with enough to not go out and buy another filter.
 
Has it been exceptionally cold for some period in your locale recently? PLXL7317? The ones I see has red silicone but standard non captured type. Assume you installed it? If installed during warm weather, possible not tightened down quite enough and cold temp contraction allowed seal to leak. Strictly speculation.

Wish it hadn't been sent off to wherever, we would have a better idea what happened with pics. As for "tech" comments, :rolleyes:. Just not enough info to make any definitive conclusion but it is very odd.

The filter was installed on Sept. 13th 2025. I don't have the filter back yet, but based on the inspection videos and commentary from the tech the gasket extruded out the side of the mating surfaces at the time of the failure event. It happened Wed. the 31st on a cold start in my driveway with the outside temp being in the high 20's (F). I've been changing my own own oil for the better part of 30 years and didn't do anything differently on this one. For the record there have been a few rather cold spells in Cincinnati since the filter was installed.

The O-Ring gasket on my oil filter failed nearly 4 months and 3000 miles since my last oil change. I avoided disaster as this occurred in my driveway on a cold start while idling. This Pentius UFXL was first filter from a case I had just bought. As you can imagine I'm a little gun shy from using them going forward. Any suggestions on why the gasket would fail after 3000 miles and 4 months? There were no signs of oil leakage prior to the failure. (note - it was not double gasketed)

Per the Amazon link given earlier, looks like it was a flat gasket and not a "P" style gasket. Did you or the dealer tech try to determine if the filter backed off for some reason over time? If the gasket actually blew out from it's groove in the base, I'd think the only way that could happen is if the filter back off some or the silicone material actually blew a chunk out of itself.

This is quite interesting and exceedingly rare. I’m not going to be discontinuing my usage of the Pentius filters, but maybe I’ll wrench tighten next time instead of only hand tighten like I’ve been doing for 35 years.

I go by the amount of turn after the base gasket first makes contact with the seat. If I can't get at least 3/4 to 7/8 turn by hand then the filter cap comes out to finish the install.

Flat gasket type. I haven't had a chance to directly speak with the tech yet, but he didn't say the filter was "loose".

I have always (Since I was like 14 years old) just spun it on and got it as tight as I could with one hand. That's it. Never had a leak, always do my own oil changes (I'm 56 now.) No idea how many oil changes. Tons of them. To be honest, not sure if I actually get 3/4-7/8 of a turn. Never paid attention. I will next time just to see how much I am getting. Like I said though, never had a leak.

You might be getting at least 3/4 turn by hand ... I usually do unless the filter is at some hard to reach location. I put a Sharpie mark, or a piece of tape on the dome of the filter after the gasket first makes contact to show turn amount, and then go for 3/4 to 7/8 turn from there.

Nice tip. I'll do that also going forward. I'm curious now! My vehicles are pretty easy to reach the filter, so maybe I have just been lucky :)
 
I have never had an oil filter fail. This event seems very strange to me. Of course, I'm sorry that it happened to the OP.
 
This is a normal failure for a slightly under tightened filter. I’ve had it happen twice on my Tacoma. Completely my fault. Usually they start leaking after a few thousands miles. Now it 3/4 right after it hits the seal. Each time I simply crawled under and gave the filter a hard twist. No more problems. Never had a problem with Pentius oil filters.
 
I just finished changing the oil and filter on the Pilot. Did a thorough inspection of the Pentius filter that went on, then pulled the gasket off the Pentius filter removed. Perfect condition. I then thought "what the heck!", and tried pulling it apart several times. Can't say I wouldn't eventually be successful if I tried harder, but it sprang back into its original shape each time with not a mark/crack to be found on it.

The ADBV looks perfect also. The cartridge is currently draining into my used oil. Later I'll wrap it with shop rags to draw out more of the oil, then will cut it off the center core sometime tomorrow and post pictures.

Not that it means much with only 3k miles on this oil, but it was not carboned up like the previous OCI. Been running only Shell premium. The filter media may tell a different story.

Sure it happens ... Like this Bosch : Bosch Failure

Sidenote - I watched that video ... no way the filter cartridge "collapsed" as he claimed. The center tube works as a column and is super stiff in compression. The filter was probably dropped and the leaf spring deformed and lost force on the guts of the filter - one disadvantage of a leaf spring, and happened on the OG Ultras too if they were dropped hard enough. The wavy pleats where not from the element collapsing ... they probably absorbed a lot of moisture from possible short trips on the vehicle.

Not all cartridge filters have stationary small O-ring stems.
