Good info straight from GM.

Reference Number: GCUS-9-11766

PF66 (GM #55495105) Oil Filter Shortage and Replacement Parts Effective 8/20/2021


Due to increase in demand in the past 6 months, the PF66 oil filter (GM# 55495105) is currently backordered.

In the immediate interim, GM Engineering has recommended the ACDelco UPF66R as the preferred approved filter.

While not equivalent with the OE filter, considering the potential impact on GM vehicle owner satisfaction, we are allowing the usage of the following aftermarket filters for a limited time until a solution is identified. Additional bulletins will be distributed advising of sufficient PF66 availability and ending the competitive aftermarket filter warranty. We will also continue to warranty the engines (subject to remaining warranty) that receive one of the following aftermarket filters:

  • Mighty – M9510
  • Valvoline – VO202
  • Parts Master – WL610351
  • Luber-finer – PH10066
  • Champ – PH10066
  • Wix – WL10351
  • NapaGold – 100351
  • PurolatorTech – TL11241
  • Purolator – L11424


Effective Date


8/20/2021


Additional information


An application guide for the PF66 oil filter has been attached.

Aren't they suppose to do that anyway per the Magnuson-Moss Warranty Act as long as the aftermarket filter was not proved to be the cause?

Or are they saying if one of those aftermarket filters listed was the cause of a damaged engjne then they will cover it under GM warranty?

Looks like it means the aftermarket filters would be allowed under GM warranty, as opposed to the filter manufacturer being liable normally for a filter failure.
