CarQuest Extended Performance EP P84047

I am not clear whether this media is considered better than the one in the Microgard/PG/Pentius Vietnam filters, any takers on that?

I’d say different. Full synthetic vs syn blend.

Is there a way to know the 20micron and 25micron efficiencies compared? Apologies if I can’t find it summarized

Love talking filters!

Yes, I’ve called PG several times now and the official PG EX(Extended Life) efficiency range is as follows. This also applies to the 10k filters made by PG for others.(Carquest Premium, Microgard Select etc.)

98.7%@15 microns(absolute)
99.5%@20 microns
99.9%@25 microns

The website has finally been updated for the EX showing 25 as the micron rating. The regular 5k filters are still incorrect and show the EX range like above(15-25).

PG has factories in Vietnam, China, and S. Korea. You will see some slight differences between factories but QC remains fantastic...

I have that information.

The white media depicted in the start of this thread is almost certainly not the same.

I have two Carquest Premiums, one Microgard Select, and one Pentius all in oversized Subaru fitment cut apart on my bench right now (thread incoming?) and I almost bought this Carquest EP on accident. I figured “known” efficiency data trumped none, as my searching (which admittedly isn’t great on this site on mobile) can’t find data on this white Extended Performance media.

The white synthetic media is 99.5%@25 microns. Here is the PG version of the EP. Same filter different color.

So "standard" premium PG filters (CQ Prem, MG EP, etc) are 99% @ 25 and the new white filters are 99.5% @ 25? Is that a real world difference to chose one over the other assuming cost was the same or similar?

The Extended PG is 99.9%@25 microns. 10k miles

The new EP and Ultimate Synthetic are 99.5%@25 microns but has a bigger holding capacity for 20k miles.

Assuming that 98.7 (absolute) at 15 is valid (I have no reason to question it) that's a new level of filtration efficiency. As far as I know, I've not seen any actual official evidence of absolute filtration of 15 microns being offered to the broader market. The leading filters will claims something 99.x or so at 20 or 25, but nobody as far as I can tell has claimed absolute levels of 15 microns.

This is a big deal.

Here’s more details. PG made Service Pro Extended Protection 10k filter.

Whoa. The fact that it has any significant performance at all down at 5 micron is notable. As is 96% at 10 micron. Dang. Most media falls off a cliff, relatively speaking as we're talking some truly tiny particle sizes.

So to confirm-- this filter is PGI made and is essentially the EP/syn media identical to the new CQP premium EP and the Microguard Select EP?

Gotcha. So unless you are running longer intervals, there really isn't any benefit for people running those ~5k intervals?

Not really. Unless you really want the nylon backing.

I'm not sure I agree with that. We haven't seen the efficiency of the standard 10k "premium" filter below the 25 micron point.

The data shown above suggests there could be massive disparities in efficiency at particle sizes below the rated 25 micron point.

In that case, there's a lot more going on here than just the nylon backing.

It’s posted above. You even commented on how great it was. We don’t have the efficiency on the new EP below 25 microns.

Oh, I thought that was the EP. Hmm, now I'm really confused. I didn't realize the service pro "EP" was the regular CQP or MGS 10k filter.

Anyway, since the non-mesh backed media is so good, I'd agree with your comment entirely. On regular intervals, the EP probably isn't worth paying a premium to get.

Last edit, I promise: It appears the missing data (in terms of < 20 micon efficiency) is for the mesh backed media, not the 10k filter.

Sorry. Right now all we know about the new EP synthetic media is the advertised 99.5%@25.

I had called PG in the past before the EP was out to get the efficiency range of 10k filter which is posted above. At some point I’ll call PG for an EP efficiency range.

I left this out of the above comment because it’s confusing. I did call PG about the new Carquest EP the day it was released. PG techline didn’t even know about it yet and reached out to engineering for me. Engineering confirmed it was indeed a PG product and unofficially stated 99%@25 microns.
