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

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.

Until about a month ago I had worked at a Chevy dealer here in town as a lube tech and I was there for 6 months, left due to horrible management but that's besides the point.

One thing I noticed about the baseplate and construction of the PF66 was only the factory installed ones that we'd take off new trucks coming in for their 1st oil change were made by Purolator.

The ones that we'd put back on were Champ Labs construction and they looked almost identical to a PF48E except obviously the center hole was much larger.

We also had a lot of issues getting PF66's in stock and we'd have to run aftermarket filters on vehicles which required them for awhile.

That's not the way it works. The only way GM can deny a warranty on the basis of using aftermarket parts is if they furnish those parts free of charge or if they can prove that your aftermarket parts were the cause of the failure. They can not deny a warranty simply on the basis of your using a non-GM part such as an oil filter.
