Premium Guard Ext Life - 99% at 25 microns, but micron rating is 42-60?

[ZeeOSix]

No, the mystery was not solved.

I hung on to this thread up until this point because I was looking for that solution, but nobody had the solution. We are still lost in the same mystery that I described in post # 30. As I did with M+H, I have written the CEO of PG to help solve the mystery, and I will let everyone here know what the response is when I receive it.

Until then I'm outahere.

My reply to you in post 32 and also in post 43 shows the ISO 4548-12 efficiency. The info is on the PG website. If PG gives you a reply they will just tell you what's already on their website showing the ISO 4548-12 info. So based on that there shouldn't really be a mystery.

Suddenly website rules. Remember Boss is 99+%@25, better than your vietnam. Until the day Purolator sorts out why the website says what it says, with test method given. Someone put it there.

That's what happens when a company changes hands all the time and they change products and never update their technical info. PGI hasn't changed hands from what I can tell.

Remember when lots of people didn't believe Fram's efficiency claims on their website, then Ascent did the official ISO 4548-12 test and showed that Fram's claim was valid. It also showed that the Boss and Wix XP were close to what their manufacturer's claimed efficiency was/is. If a company like PG has an ISO 4548-12 efficiency claim, it's most likely pretty accurate unless things are constantly changing with the product and they don't keep up with the technical info given to the public.

We can always have a wager, have some filters sent in for an official ISO 4548-12 test and the loser pays all the testing bills, lol.

After calling PG tech support I finally got an answer!!

The micron rating range of the PG XL is 15-25. Meaning 98.7%@15 and 99.9%@25. The micron rating range of the regular PG is 42-60 98.7%@42 and 99.9%@60. The significance of 98.7% is an absolute micron rating for automotive oil filters.

These ranges are under the wrong filters on the website in error. I figured this out after the fact by looking up a regular PG and PG XL for one of my cars. At some point I will need to call back tech support to let them know.

Good info. So they are even better than what the info on the PG website shows. I'll admit that how they express the info on their website could be cleaned up, but what's there now does show their Extended version of the filter is 99% at 25 microns and greater.

Great info. Thanks for checking.

Too bad for that one dude. He ducked out of the thread a few hours too early.

So my question now, is the Carquest Premium the same as a PG XL or a regular PG ?

XL

XL

Thank you!! I was sweating there for a minute thinking that I might need to switch filters yet again!

@Glenda W. has posted the service tech sheet on the Carquest Premiums in various threads. Maybe she can post it again here.

I pointed this out in post #33. That is the reason I started asking questions about the Premium Guards.

We should be charging to find website errors at this point!

 

[ltslimjim]

Seems pretty definitive about the performance. The hero we needed but not the hero we deserved?

Maybe tongue in cheek; other local brands selling out for poor quality and having to important a better product! Grateful to have them as the go to for now!

Thanks for all the up to date info and clarifications.

They are all playing funny little games with their 99% efficiency. they need to be forced to list it on every box at 20 microns as consumer protection.

 

[Fair enough]

There are still USA companies making filters that are good to select. Even with all this fanfare about PG.

forced by consumer protection? There is news about that.
