Apologies if this subject has already been previously discussed, but I couldn’t find a thread if I has. I found out last year when I changed my oil in my ’24 6.6 L5P the PF63 oil filter has been changed. The new Oil Filter I bought (PF63 Part Number 12735811) did not look like the Oil Filter I removed (PF63 Part Number 12731742). The difference was on the threaded side. The new one appeared to be missing a pressed on cap or cover. Here’s a link to a video where a guy cut the filter open to compare both filters.
They appear to be exactly the same internally and the only difference is the missing pressed on part on the end cap. This guy thinks it may increase oil flow, but I have seen nothing from GM or AC Delco to explain the design change. IMO the old design filter secures the rubber gasket better. I’m thinking about going with another brand of filter when I;ve used my old style filter stock. But the interesting thing is the PF64 on my wifes Equinox changed too in exactly the same way. I’ll bet it was a cost savings thing. Anybody have any additional information on the change? What filter brand is everybody running?
PF63 Oil Filter Design Change

I reached out to GM about the change in filter design and respective part numbers for the PF63 (1st gen - 89017525, 2nd gen - 12731742, and 3rd gen - 12735811). I recieved this answer. "We periodically make engineering changes to our filters. Rest assured the PF63 meets the specifications for your vechicle." They did not address my question of "Why was the filter design changed?"
I found this video this morning and IMO it is excellant. The fella does not address why the design was changed, but you can clearly see the differences in the 1st, 2nd, and 3rd generation filter threaded end caps. Visually comapring the 2nd and 3rd generation where I have said it looks like a piece of the end cap is missing, the holes in the metal are larger on the 3rd gen filter. So theoritically GM omitted the piece and enlarged the holes for more oil flow capacity. It would be intersting to know if the oil flow capacity changed and how that effected oil pressure.
But in the video you can also see metal shavings on the filter threads which is alarming. Still switching to Baldwin.
And I also think i've beat this drum enough so I'll stop now. Cheers all and thanks for your input!

II have looked at this filter when changing oil on my sons EcoBoost engine then did some research on the filter. The oil filter geeks like this filter. The specs suggest it should fit the Dmax just fine. From what I had read and could see it is a pretty sturdy and well constructed piece.
The logic puzzle is that the Fram website does not list this filter for a Duramax but it does for the gas engines. AC Delco list the PF63 for the gas engines as well as the Dmax. If the 63 fits gas and diesel but the 10575 only fits the gas is that a spec, cross-reference or something else? Gaskets, threads and bypass pressures all the sameish.

As AlisoBob states the Wix XP has a larger micron transfer allowance than a standard Wix. My local parts store has told me the the XP is for synthetic oil. Well, that is not really true. What is happening is oil change intervals have grown to 10,000 -15,000 miles. That means the filter needs to not get plugged up in these new extended mile recommendations from the manufacturer. Which is a government thing, NOT something good for your motor.
So Wix made the XP line that allows larger particles to pass through the filter than their standard filter. So by not catching as many particles the filter is designed to last for the longer oil change intervals implemented by our government. I have not looked at the exact micron difference between the two but it is something like a 5000 to 10000 micron difference. Sticking to 5000 mile oil changes and the standard Wix is a better choice for longevity. With Wix the filter number is usually the same for XP and non XP version.

We own a generator sales and service company in CA. Only use Baldwin for our service except when OEM is required. Same for our Duramax powered trucks. We did try the Wix XP on our 6.0L gasser due to the salesman says that it is designed for Synthetic oil specifically. And says so on the filter. No issues. YET>>>

You prefer Baldwin over Fram FE10575?

Boy.... thats a tough one. I've cut apart LOTS of filters. Never seen a bad Baldwin. I've seen bad Fram filters, but the FE10575 is actually made by Champion, which made a terrible run of Mobil 1 filters, which they destroyed after I alerted them of the poor quality and massive glue mess going on inside. They actually destroyed 2 production runs of filters!!!
I run the Fram Synthetic Endurance filter on both my Gen 5 Camaro, and Gen 2 Traverse. I bought 12 filters and cut one open to check the quality, and it was fine. I'm assuming the other 11 are too.. Consumer Grade oil filters are terrible as far as QC goes. The Baldwin is Professional Grade, but with slightly lower micron and efficiency numbers. You need to make this call, with what you're comfortable with......

Thanks Alisobob. I read your stuff and trust your opinion and was shocked when you actually liked the Fram FE mentioned. I’ve cut two open, 1 new and one after an oil change and they looked good. Seem a bit tinny though.
Thanks Alisobob for all the info you've posted on this subject. I saw this posted on a FB Page for Chevy and GMC HD Trucks. Seems I'm not the only one interested in selecting the right filter and moving away from the PF63. I've quoted the poster from the FB Page below. I don't know the poster and have not researhed his findings myself. Seems to be several filters out there better than the PF63 as far as filtering and efficiency. Understanding from the findings you, others, and I have found the internal construction of filters are not the same. (your info on the Mobil 1 construction and Wix XP filtering was eye opening) Baldwin has them all beat with their quality. Still plan on switching to Baldwin.
Wondering if these numbers are accurate and your thoughts.
Quote from the other page:
AC Delco PF63 (OEM), 22 PSI bypass, 30 micron 98%
Purolator Boss PBL 22500, 22 PSI, 25 micron, +99%
WIX WL10255, 22PSI, 21 Micron, 99% (99% is from O'Reilly's. 21 micron from Wix website but they don't disclose efficiency %)
Mobil1 M1-212 A, 22 PSI, 21 micron 99.6% (From O'Reilly. Curiously, I e mailed their tech dept- they declined to disclose micron and efficiency?)
Any opinion on Donaldson P577066 for the 3.0?? Donaldson is a go to for many Fleet managers.

Me too!!!!
Champion labs makes both the Fram FE and the Amsoil Filter now. Fram makes nothing now. The company who bought it, bought the name and basically threw out everything else.

Donaldson are very well made. Wonderful filter and company.
They used to make the Amsoil filter, until it got farmed out to Champion.

No way....... Mobil's website list's it at 99% @ particles greater than 30 microns.
Has anyone cut apart an Amsoil oil filter to inspect it ..? This is what I use and would be interested in what you found. Thanks

Much like oil, if the oil and filter are changed regularly, the minute differences in various filters won't likely make any difference. Personal preference and good maintenance routines.
I upgraded the cooler on my 20147 to the newer style as mine was leaking, not happy with tiny filter, tried oilagra no effect! so bought a stud that screws in to change to old style thread, new is metric, old is SAE, I just have to see if there is enough meat on adapter for larger diameter filter
