As for AZ XL site info, my speculation is info remains from previous S. Korea manufacturer Daewha, who also had same efficiency information on box. Google search of this site will also confirm that information. Also Premium Guard are noted to be "99% Multi-Pass efficiency and removal of particles as small as 25 microns ", not 20um. "If' XL is a PG as stated, further proof AZ site info not current.




The 25 microns... Was for their lower tier filter....

20 was the black one.... Which is the same doggone filter at Federated Auto.... And the information from FA own site mentioned 99 percent at 20 microns... Same NOW that mentioned on AZ site... Not a coincidence.... They are the same exact filter. But the way...... When the PG filters took the place of the Purolator made ones... Shortly after that the AZ website changed and put the ISO test efficiency numbers back on there again.... Those numbers were not on there while Purolator was making them.

Strange I agree... But it made sense...

By the way .. on a very good positive note sayjac....

I really appreciate your work on here. You have helped me in regards to what filters are good in the sizes I use. You do a great job on here with that. Again... Thank you for your work on here. It is top notch.

On topic STP blue and the XL. The "STP XL" was first introduced at AZ in 2015 (bitog search), before that afaik there was no such filter at the Zone. At that time they were made by Daewha in S Korea and the box also said then 99% >20 microns ISO 4548-12. That efficiency information is apparently still on the AZ website. Since though as seen here the topic filters, have moved production to China, no efficiency rating.

It was posited that the XL is the same as the Premium Guard now with same coo, possible, though other than looking similar I have no way to confirm. As also noted Premium Guard XL black is rated 99% efficiency on particles as small 25 microns. That straight from the current PG website. https://www.pgfilters.com/oil-filters/#extended That information doesn't align with current AZ website information.

As for latter added Federated filter, know nothing about that filter other than what's been posted here. That could well be a PG too, like XL looks similar.

All that said, as chance of using STP XL, blue or any STP very small for me, mostly an academic exercise. IMO regular price STP OF too high and there's no 7317 application size, only 6607. Unless part of some stellar AZ oil&filter promo deal unlikely to use one. For me, the last one of those was in 2011-12 Mobil Super 5000 and STP blue for ~$10. Rather than using shorty 6607 used the Champ made S2808 on a Civic.

It's the same blanking filter..... Get over it...

If I have a Federated Auto filter and pull off the sticker.... And I get a AZ xl filter pull off the sticker... You would not know the difference. Cut them both open... They are the same... Get over it.... They are the same... Whether you, I or Ray Charles like it or not...

Has far as the numbers... Well numbers can be found stating what the black xl filters did say on the Federated Auto site.
Fun fact for the day.... Found PG site easily I might add.... First thing mentioned on ex filters....aka same exact one has Federated Auto has and AZ.... 99 percent at 20 microns per ISO etc etc.......

Again the ex is used in the same has Federated Auto filter. AZ uses different numbering system. But it is still the same filter has Federated Auto..
Heck... I will go buy one of both.... Just to prove beyond any doubt they are the same... We will play the game of guess which one is which... Pull stickers off both. That will be fun times

I think PG site is similar to Wally world website... Aka bad info all over it

Seriously. All it takes is one world champion typing something in wrong and it is all jacked up. The AZ and Federated Auto information is the exact same. Yet it's different on the pg site... I'd bet dollars to donuts that the information is correct on AZ and FA.

Just like I could not trust Wally World when it came to the Valuepower group 24f battery.... Wally World website said it was the 624fmf battery... I did not believe it. But by goodness when I weighed my battery and it actually did weigh 41 pounds then I knew that the part number from Wally world website was actually correct. Hard to know what the deal is at times.

 

[Sayjac]

You need to chill out dude, you're going to give yourself a MI over a filter. If you have an issue with the PG link posted showing the claimed maker Premium Guard saying the XL "99% efficiency on particles as small 25 microns" you should take it up with them. Here it is again. https://www.pgfilters.com/oil-filters/#extended. Using the claimed maker Premium Guard as main information source only seemed logical. Now it appears, claimed maker Premium Guard site is mostly inaccurate, "bad info all over it"? If that is the case, then doesn't speak well for them as the manufacturer imo.

That said, I allowed that topic STP XL could be the same filter as the PG XL, just pointed out discrepancy in information between topic filter with no efficiency on box and the PG XL website info.

 

[bbhero]

They are the same... Whether you or I like it or not...

I will buy both... Pull stickers and play the game... You guess which one is which

Again... The information from websites can be lots of fun at times.... Has evidenced by Wally World... That site information you put there is obviously on their site... But that doesn't mean it's gospel...

I bet some typing world champion jacked up the information on the pg site...

And I am not upset with you at all...I am just being very straight forward today... My bad

I am sorry for being too cantankerous..

Some days I am just like that. This typing things out can be not always the best way to go at times.

I appreciate your good work on cutting open those filters you run. You really do a great job. And that is very helpful to me has well plus everyone else.

I also like your take on the Scotty thread by the way... You were right on about that being funny...

 

[Sayjac]

No problem. What are we talking about, mainly 5 microns, pretty funny when you think about it. Fwiw, looking at pics, information and coo I'd say good chance all three XLs are the same, just as you say. So don't waste your money buying them for my benefit. So as Scotty might say... Hey, no problem.

 

[bbhero]

Yeah it's all good...

And seriously I respect what you have done on here... A lot. Yourself, Robert, and Strude53 are the best on here in terms of tear downs, analysis, and assessment of the filters out there.. You are a bad manma jamma when it comes to that skill set. One of the best man. Seriously.

Hey man... I'm glad you are on here too... You add a whole lot of great information on here. Between yourself, Robert and Sayjac we got the best team here for filter break down, assessment and detailed analysis.

Just as an FYI...

Champ has an "office" in Shanghai...not manufacturing facilities. Years ago they had an air filter plant, but closed it quietly after the Fram merger (and before the subsequent "divorce").

As to the product seen on shelf at AZ...see below.

IDUSA...now PGI...has the lions share of the AZ business. Champ is second and IPC carries up the rear. They supply different stores by DC so PGI product will be in stores serviced by PGI supplied DC's. The plastic film on the bottom of the import filters is for the long boat ride over as a rust resistance... Barring the obvious component differences...the media could very well be the same on the PGI versions for economies of scale. However much you trust that is up to you on whether that's a plus or a negative...

 

[WellOiled]

Hannibal - Thanks for the clarification. It does make sense.

 

[wemay]

Excellent, informative post. Thanks Hannibal.

 

[Sayjac]

Having visited some AZs locally I can say this, with the exception of slow moving application/old stock left all Champ US made AZ STP filters now gone from area stores. Before that the lowest tier blue was the only Champ US made STP anyway.

Based on anecdotes posted, filter construction of any AZ STP filter bears little resemblance to any Champ US made filter anecdotes eg., Super Tech, Mobil One, K&N and former FoMoCo factory filters. No Champ US uses a coil compression spring, all flat/leaf. Also bypass designs whether dome or end thread end different. Champ US uses either blue button dome bypass as seen recently with Super Tech 6607 posted here recently. Or they used clicker type bypass like old S2808. The unique thread end bypass seen in M1, current K&N and former FoMoCo factory filters, not seen either. As opposed to topic, Champ also uses louvered centertube. So while Champ may now have some operations in China, my speculation is current STP here not associated with Champ US. AZ does now carry a decent selection of Champ US made M1 and K&N applications.

For STP MaxLife, the S6607ML and S2ML now show China coo too. Like the blue and XL, as stock moves off the shelf appears Purolator made ML is being replaced by filters with new coo. ML seems to be slower mover than blue and XL, ones mentioned likely faster sellers.

Sayjac, here's a recently bought Champion COS3593A. The equivalent to 2808...

Sorry about the orientation. I just noticed but it's too late to edit.

It seems safe to me to conclude that AutoZone is using champ as their vendor for filters. Champ appears to be out sourcing it's labor to some of the same manufacturers as premium guard and maybe eco guard as well now instead of making them all here at their own plants.
I ordered some champ cartridge filters few years back on Rock Auto and got a mix of USA, poland, Indian, made fters so outsourcing is nothing new for them.

 

[Job]

Not to make waves, but the Champ link says new facility in 2017, not office. The film is to keep the filter clean IMO because they always have a small puncture in them, which allows atmosphere to enter, but 99,9% of the dirt floating in the air is kept out. It may cut down on the rusting a very little, maybe not at all, but I think it is more they care about getting dirt into the filter.

Read Hannibal's post....


Mostly PGI, then Champ etc etc... PGI is premium guard... And this manufacturer gets the Lions share of AZ filter manufacturing.
