PF48 > PF63 > PF64 Question

[revrnd]

I've known that the PF48 (short) & PF63 (long) variants interchange. But today I found something online that puzzled me. On this cross-reference site:

http://www.oilfilter-crossreference.com/convert/AC-Delco/PF48

that a PF64 is a PF48 equivalent. Can someone confirm this? Any details on this PF64 filter?

Specifically, per #15-00-90-002:

"The PF63E primary performance improvement relates to the bypass valve design. The ACDelco PF63E has a compression spring loaded nylon poppet that outperforms the current valve design.

Other benefits include the following:

-Designed with five times greater burst strength than most engine oil operating pressures after the oil reaches operating temperatures.
-Bypass valve opening pressure has been increased from 100 to 150 kPa and is statistically more capable.
-Patented cellulose media traps particles that are 1/3 the width of a human hair.
-98 percent single-pass filtering efficiency at 25-30 microns.
-Hot oil durability has been improved by the elimination of adhesive.
-Improved level of robustness to water accumulation.
-Excellent cold weather performance -22°F (-30°C) when using dexos1.
-The element integrity (collapse strength), remains the same.
-The excellent filtration performance (efficiency and capacity) remains the same.
-The filter shell configuration is unchanged, which means existing oil filter cap wrenches continue to fit."

What a screw up on the part of "The General". In the 80s when we were building C/K trucks, the engines were shipped to the assembly plant bare (carb', water pump, distributor & exhaust manifolds were installed). The oil motors were 'dressed' on the motor line w/ the proper filter (& other accessories). None of this "Replace build filter w/ PFXX at first oil change".

I was thru the St. Catharines motor plant around '84. The engines were test fired before shipping, not sure how this was done w/o a filter.

I wonder if Fram, Wix, etc have a bypass valve setting that matches the PF63E, or of it is a more generic PF48 one-size-fits-all setting?

You just posted to rant about GM? So glad I took the time to provide info.

Here are the links you need. I'd do the work for you, but then I'd probably just hear about how terrible Fram and/or Wix are...

They bypass is more relevant to the filter itself than the application, as it needs to bypass before the differential pressure is too high and collapses the media, so it might be different between filters made for the same application.

My malibu takes the same filter.

Thank you for the link. My rant about GM's design screwup stands. Working as a tool & die maker there for 28 years I thought I'd seen everything. Oh & thanks for the assumption about my views on oil filter brands. A couple of items in my current inventory:

 

[revrnd]

I've used WIX filters starting w/ #51522 when GM/AC Delco obsoleted the original PF61(?) (that my 2004 Silverado 2500HD used) & replaced it & several other oil filters w/ a shorter PF46 filter.

The original PF61 (Non E-Core) is still readily available, I bought one last week for my Tahoe at O'Reilly, And Walmart is fully stocked with the PF61E. Though I don't see using a PF46/PF46E as an issue at all.

I don't have the '04 that I was using the 51522s on. My previous truck, a 2011 Silverado HD spec'd a PF48. I had been using either a PF63 (non e-core) when I could find them or a WIX 57045.
