Oil Filter Thread

[Burla]

I still haven't seen anything better on the shelf for a long interval then boss except travis's EP. By the way I don't know if it was said, if so apologies, but EP is to advance auto parts like endurance was to Walmart..

You can exclusively purchase the Carquest Extended Performance (EP) oil filter at Advance Auto Parts. Since Carquest is a private-label brand owned by Advance Auto Parts, it is not officially sold at other major retailers like AutoZone or O'Reilly

Same manu as microguard, but better as that is a blend, EP full syn.

So what's up with Zee's comment in reference to the Ascent test showing it as one of the worst along with Wix, and then worse later?

What is with multiple, opposite, "data"?

Btw, here's the construction of PGI (Vietnam) I use in Harley. It appears the same in my inventory, no need to cut open. I can see the wire mesh and the white filtration media. Heavy gauge canister, etc.

But they won't make this for the auto market, unless Carquest EP is it?

 

[HEMIMANN]

So, the Ascent test from 2021 showing Purolator Boss being a rock catcher was completely redesigned by 2024?

IDK, I'd say I'd trust the CarQuest EP or Premium over Purolator inconsistent data at this point.

 

[Burla]

90% at 25 microns and close to 100 at 30 microns, way better then wix xp when it was actually synthetic. You see wix now media looks like any trash media out there. The guys Blackstone uoa suggests that puro boss gets better as it goes, .2% solubles at 18k miles. Real curious at Blackstone proof of insolubles with paper filters at over 10k miles, even less. I have no idea about that info, but I'd like too. That thread you posted was puro's own data, who does that? Nobody posts their tests like puro did, hats off to them. I have seen nothing except for perhaps EP bought at advance that is in puro's league. Just my opinion, there are only two filters OTC suitable for the hemi on a long interval boss and EP, that's all I got.

More recent on Bob's: April this year. Boss is a rock catcher. CarQuest is PGI, advice is to go with the 10,000 mile "Premium" and forgo the 20,000 mile "EP"........apparently they loosen the efficiency of the EP to gain more dirt capacity in the same size can. When I'm out of legacy Fram FE and Royal Purple oil filters, I will go to CarQuest Premium. By that time, there may be no oil filters left in the world that are any good.

Brendan is a lube guy also on Harley Forums...

Food for thought, one thing i have learned in the oil filter wars is that 99% of all manufactures only test certain poplar oil filters and then try to convince you all of the other filters they make have the same micron ratings or are equal to those tested, if I owned a Hemi I would spend the coin on the Fleetguard stratapore oil filter, last I looked one up I recall it was rated at 99% at 24.6 micron..

Don't make one for Hemi. I checked. I'd discussed this at length with Travis - they only make the paper element filter.

But check this out - Donaldson makes a blue synthetic hydraulic oil filter for my John Deere Tractor hydrostatic transmission! Oil filtration business is insane.

Zee is not a fan of boss. He has emailed them many times over the years for efficiency data and they always say 99% at 46 microns. Today i think they say efficiency is proprietary info. That being said zee is the oil filter geek. Most knowledgeable filter man ive seen over there

Here's my problem with this Travis - 5 years ago ASCENT lab showed Boss was a rock catcher.

Two years ago this random guy's test shows Boss is as terrific efficiency as Fram and Royal Purple.
No explanations, no different product type. Just P.F.M.
Sorry, too spooky for moi.

It'll be PGI for me after my stock or I run out.

The options in my city seem pretty limited. You can find the crappy paper filters anywhere but quality true synthetic filters are hard to find.

Even the auto parts place by my house didn't have one sitting on the shelf. They stock Wix and their house brand. They didn't have any Wix XP either which is strange if you sell Wix filters. The XP are nothing special anymore anyway as they cheapened them by making them a blend instead of a true synthetic.

Right from the Wix website.

Just using the acsent graph it doesn't suggest puro boss is a rock catcher. Wix XP is the rock catcher, we don't even know the size of particle it traps at 99% because it falls off the graph at 55 microns. You can see at 30 microns it is as good as anything. It most likely is the difference between spun glass and poly. Every other test showing boss is the boss. Not sure why Brian seams like running on and on over nothing and old posts, but its a free world. I'm always open to new information and changing my opinion on it, but you failed dude. Go back to the interwev to prove your point with something better. Might wanna find a way to at least address the tests I posted that showed boss is the boss instead of using a graph I posted 5 years ago that doesn't even make your point.

I don't get it. Both curves are similar.

In general, what does he say about the different filter technologies, blend, paper, versus spun glass and poly? Many bitogers like paper as much as they like conventional oil, which there is a fair share. They ignore science and go to the I've been driving for 40 years on this philosophy. Which I must say has been a legit argument with older engines. Not sure these things are going to fly with modern engines.

 

[Burla]

Look at the values? And the curves aren't similar, wix XP never shown to stop any size micron tested in graph limits = rock catcher.

 

[Burla]

Is Carquest poly or spun glass?

It was my understanding the Fleetguard LF16002 ( its an upgrade of the LF3681) not sure if it's a Stratapore, but it is rated at 100% at 24.6 micron

I did - the Purolator Boss and Wix XP follow the same trend line - both rock catchers. The Fram XG (original) and Royal Purple are the efficient two. We discussed this years ago.

Then this other guy pops up and shows high efficiency with Purolator Boss. Then Zee0Six pops up and says Purolator wrote him back saying Boss is a 46 micron filter in the 99% range, same as ASCENT test results.

Sorry, I won't be using an iffy filter like Purolator, Boss or One. Nor can I recommend it. Based on completely conflicting data we have been shown.

Efficiency is the most important feature of an oil filter. Otherwise there is no point having an oil filter at all - because the wear particle regime is proven to be in the 5-25 micron region (lake speed engine wear tests, others). If you're only gonna filter 20% there, it's damn near useless.

Yes, we need flow and capacity too. If these are concerns due to lack of data, then change the damn thing more frequently than >5,000 mile OCI. Which is what most of us do anyway with Hemi engines. And so, I will go with CarQuest quasi element Premium Oil Filters and 5k OCI's if and when I run out of Fram FE and Royal Purple Oil Filter inventory.

That's all there's to this. New information that is completely contradicted by other sources is not useful to me. Neither is who is right. I make decisions on the most data I can get at the time the decision is needed.

In fact, I have a whole case of Fleetguard Oil Filters I mistakenly though was their Stratopore Glass Media that turned out to be paper I plan to toss out.

I don't remember the numbers and I'm not going to look them up again. I spent hours looking this stuff up last winter and discussing with Travis. We confirmed the filter for Ram was NOT Stratapore - was paper. If I get around to it I'll share what I purchased that is not stratapore that was touted to be stratapore. Sitting on a basement shelf waiting to be tossed out.

So it looks like they made some major changes since I last dove into oil filters for the Hemi, must be a low volume filter so to downgrade it to paper media, but then I also recall it fit most Ford gas engines so who knows, it's too bad oil & gas filter manufactures play games by using different filtering media in a lot of there filters and then keep it a secret so you have no idea what your buying.
