Spin-On Oil Filter Replacement

The correct match of oil filter to engine application is more important now than ever with the tight tolerances, two stage oil pumps and high flow lubrication requirements of today’s modern engines.

Beginning in 2012, oil pumps began to regulate main gallery feedback instead of pump output pressure, which means that the oil pump does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.

To meet these new engine operating requirements, the oil filter specifications of production oil filters and service oil filters have been improved. If a replacement oil filter with an internal bypass valve opening pressure specification of 15 PSI (100 kPa) or less is used, debris could circulate in the engine and cause damage to bearings and other tight tolerances areas, and eventually lead to premature engine failure.

PF64 and PF63 Filters

The PF64 and PF63 (Fig. 20) filters are commonly confused as an ACDelco PF48 and/or PF48E filter because both oil filters have the same appearance and oil can size. However, these oil filters are not the same and have different internal bypass valve opening pressure specifications. The PF48/PF48E has a pressure specification of 15 PSI (100 kPa) while the PF64/PF63E has a pressure specification of 22 PSI (150 kPa).

Fig. 20

Refer to the Electronic Parts Catalog (EPC) to determine the proper part numbers for a replacement oil filter. If an aftermarket filter is used, it must have an internal bypass valve opening pressure specification, element integrity, filtration performance, media particle trap specification and burst strength that is equivalent to the original production oil filter.

Depends on the engine - as always - follow your owner's manual..........

From my 2017 6.2L manual:

Maintenance Replacement Parts

Replacement parts identified below by name, part number, or specification can be obtained from your dealer.

If the vehicle has a diesel engine, see the Duramax diesel supplement.

4.3L V6 PF63E

5.3L V8; 6.2L V8 PF63E

6.0L V8 PF48E

It's just a shame that GM/AC Delco dumped the original PF-63 in favor of the cheaply made PF-63E. E-core junk with a weak plastic cage and a poorly bonded filter element.

The Mobil 1 M1-212 has the correct bypass pressure and it's construction is much more solid (steel center tube, glued steel end cap, better bypass valve design, etc). O'Reilly Auto has deals on Mobil 1 filters from time to time to make them more affordable.

Never seen an E-Core fail and that's all we use at work.

Internet lore...even the high dollar filters will have failure, the ecores were under a lot of scrutiny when they first came out, and a few were found bad and that was what sealed their fate about being a bad filter. I have never actually see a bad ecore in the filters I have cut apart (yeah, I have a can cutter).

A few good filters were found with torn elements too (Purolator)...not much was said about that. And I bet a lot of guys still think Frams are junk too...they are one of the better filters out there now.

Where do you see the bypass pressure listed for the m1-212?

I can't seem to find it listed anywhere, on m1 site or anywhere else.

Do you have a link.

I've been using the Wix 57045XP

It lists the the bypass pressure at 12-15 PSI

I've always been happy with wix products, I feel they're good quality and I can get it for half the price of the M1

Can't go wrong with Wix...I've been using their filters a long time. The only time I use another filter is if Wix doesn't cross to the application or doesn't meet the spec.

I see that now on their website, that's good information, thank you.

So, now after reading that article about bypass pressure, I'm not sure if the Wix is ok, being that it's rated vat 12-15 psi

I guess I'll have to step up and pay for the m1 filter. I have 3 of the Wix filters to use up still, not sure if that would hurt or not. What do you think?

I've used Wix, Fram (Ultra), Mobil 1, and AC Delco brand filters so far. I just put on a Fram Ultra along with Quaker State Ultimate Durability 5W-30. Oil pressure looks normal, engine runs quieter, and it hasn't blown up yet. I used a regular old Wix 57045 when I first started changing my own oil. Had zero issues.

I wouldn't get too worried about it. Like I said, I'm just not a fan of the E-cores after seeing all the failures online, plus cutting open one that came off my truck that had the filter media un-bonded from the end cap. Everyone says the "thermal bond" is stronger than glue... didn't look like it.

Just search Google Images for "E core filter failure" too see how great those new, cheaper made filters are.
