A/C Delco Oil Filter PF63 E? F? or just a 63?

[Triton_330]

The "F" stands for "Fleet" by the way.

The PF63E’s primary performance improvement is the bypass valve design, with a compression spring-loaded nylon poppet that outperforms the current valve design. Additional features and benefits include:
 Element integrity (collapse strength) is unchanged
 Filter media is no longer potted in adhesive which blocks filtration area at each end
 The filter shell configuration is unchanged, so existing cap wrenches continue to fit
 Bypass valve opening pressure is increased from 100 to 150 kPa
 Hot oil durability is improved by elimination of adhesive
 Cold weather performance (-30 C) with dexos1 oil is excellent
 Improved level of robustness to water accumulation
 PF63E filters are expected to be used in OE production in the near future.

Per my compatriot at the local Chevy dealership...

PF63 = the regular ol' design with steels guts (just like factory design). There's a dfference in how the original factory ones are made versus the service ones, but he could remember what. Both are the "steel" design though.

PF63E = the ecore design GM&Delco instruct to replace PF63's. This is what they sell to a customer at the parts counter.

PF63EF = a whole case of PF63E's without a AC-brand box >> just filters in a carton. This is what the dealership techs use in the service bay.


He also claims they use the PF48E instead of PF63E from time to time.

Yeah, I'm gonna go out and spend $50,000 for a brand new Chevy truck and then save a few bucks by buying an e-core filter...


Both were designed by GM......


Nate, exactly! Maybe Merk should notify GM that they are going to be replacing millions of engines because they instructed their dealerships to use such an inferior filter! LOL.


Apparently the filters pass all the right GM tests, otherwise it wouldn't be permitted on their vehicles under warranty. I don't think GM/AC messes around with inferior stuff anymore given the recent issues (ignition, airbag, etc).

There are plenty of plastics which perform greatly in hot oil. The common ones are nylon 6 and nylon 6-6. When I was working with injection molding materials this stuff was common as could be, just that it beats up molds more quickly due to the glass fiber filling in the material.
