That bulletin is from 2015, it concerns the 3.6 V6 engines, and is telling us dealers to use the longer 63 filter in place of the 64 filter that was used during engine assembly due to there being clearance issues at the engine assembly plant.

It doesn't concern any of the V8 engines, and the part number listed, 19330000, has been changed to 12707246.

Right, I just spent 4 years with dealers knowing nothing about what filter I should use on my 2017 impala. Because of that I don't trust them saying again to use a different filter than my 2021 silverado owners manual says.

The PF63E has been replaced by the PF63, same with most of the other filters (IE- PF64E is now PF64) GM has dropped the "E" designation, the design is the same.

I personally run a UPF63R on my 2015 Silverado 6.2 (As well as a UPF64R on my '18 Cruze and a UPF48R on my '11 Camaro SS)

Ok. I really wish acdelco and GM would put out some info so it's not so confusing. It's just stupid of them to give me an owners manual that's 3 months old with part numbers that are to parts that are no longer made. He'll they could just print on the side of the box that it's a pf63 filter and a true replacement for the pf63e. I would think that would cost nothing to do. Thanks for your info, the 3 dealers I visited just told me " that's what they use and that's what they carry and they cold order the e version if I wanted it." Some kind of print out they could hand to me explaining what you said would be great.

Well if your 2017 Impala is a 3.6 V6, it uses the newest 63.....GM part# 12707246

You have to understand, that owners manual is more than 3 months old, it may have been printed a year ago, its not as updated as our database is from GM, part numbers change all the time, lord knows I've seen numbers change many many times in my 30+ years in the GM parts business (about the only part number that hasn't changed is GM's optikleen windshield washer solvent! 1051515)......other than that every number has changed over the years, and they can't reprint and send out new owners manuals everytime the part numbers change, but I understand your frustration, anyway the newest number is the PF63 / 12707246 for your truck, or as I said I use on mine you could use the UPF63R Ultraguard Gold filter.

Okay I just looked up the GM 12707246 as a cross reference for a WIX and got a match for the WL10255 which has a 22 psi bypass spring. Same as the old PF63E.

 

Then I cross referenced a UPF63R and got WIX WL10412 which as a, ready for this? A 36 psi bypass spring!!

 

Lastly I cross referenced the PF 63 and guess what, WL10255. This use to cross to a WIX 57045 with the 12-15 psi bypass once upon a time.  

 

 

 

I have the WIX PDF for this update but it is routed through my PC so will not share that file in forum. 

 

So....here's the 411 on this cluster ****. GM is once again using the superseded (old and origianl part number), PF63 to replace a newer but no defunct part number PF63E while KEEPING the 22 PSI bypass spring.

 

They must feel confident that ALL NOS PF63 filters with the older 12 psi spring have been purged from EVERYONES stores. 

 

Purolator PL22500 is the cross for the CURRENT ACDelco PF63 and FORMER PF63E 22 PSI bypass

Purolator PL22500 is the cross for the OLD/CURRENT WIX 57045 and OLD PF63 but keeps the 22 psi bypass

Purolator PL21495 is the cross for the CURRENT ACDELCO UPF63R. 36 psi bypass. 

WIX 57045 is the CURRENT and OLD cross for the FIRST USE of the PF63 ACDelco. 12-15 PSI bypass. Purolator no longer carries a 12 psi version of this filter. 

 

Bottom Line: No matter what is printied on the box or in the manual the CURRENT bypass spring is 22 PSI. Use a Purolator and end this madness.

Going to pick up a Purolator or Wix replacement with the 22 psi bypass today.

The parts store near my job should have one or the other.

 

What a confusing mess.  

I appreciate everyone helping shed some light on the different twists and turns of the apparently “new” PF63 (GM 12707246).

Not confusing at all, just use the 12707246 and you'll be fine.

Yea. I wish I meet you in the parts department instead of someone saying I don't know. This is what we use. I pretty sure I use the UPF63R in our 2020 blazer 3.6. I would like to use that filter in my 5.3 silverado. GM makes it so confusing I just use whats in the manual so there's not reason for a warranty claim to be denied. I wish I could see a statement from GM saying what filters I can use.

Yes, GM actually requires the use of the UPF63R in the 3.6 Blazer (as well as some other 3.6 applications such as the Camaro) due to the higher oil pressure.

You would be fine to use it in your Silverado, its actually listed in the parts catalog as an optional service replacement.

#20-NA-213: Information on Improved Oil Filter Gasket Design for Spin-On Oil Filters PF63 PF64 and PF48 - (Oct 30, 2020)

Subject:

Information on Improved Oil Filter Gasket Design for Spin-On Oil Filters PF63 PF64 and PF48

---

Brand:	Model:	Model Year:		VIN:		Engine:	Transmission:
		from	to	from	to
Buick	GM Passenger Cars and Trucks	2011	2020	—	—	Engines that use a PF63, PF64 and PF48 oil filter	—
Cadillac
Chevrolet
GMC

 

Information

Starting October 1, 2020 replacement spin-on oil filters PF63, PF48 and PF64 will come with a new improved gasket design to help retain it to the oil filter body and eliminate the possibility of the gasket from falling off during installation. The gasket width was increased to help retain the gasket to the filter body. Existing dealer inventory or filters received from CCA are ok to use for service. When replacing an oil filter, always ensure that the gasket is seated properly in the filter body. These filters meet all GM OE specifications and are approved for service usage. Today's engines have very tight tolerances, multiple oil pressure control systems and high flow lubrication system requirements. These requirements will vary based on the specific engine design, so the proper match of oil filter to the engine application is very important.

Refer to the Electronic Parts Catalog (EPC) to determine the proper part number for your specific application.

Information

Today's engines have very tight tolerances, multiple oil pressure control systems and high flow lubrication system requirements. These requirements will vary based on the specific engine design, so the proper match of oil filter to the engine application is more important than it has ever been in the past. The High Feature V-6 engines RPO (LGX) and (LGW) have higher oil pump pressure to accommodate engine cam phasing and high-speed bearing requirements. As a result, the oil filter performance was improved to meet this higher oil pressure output. The new UPF63R oil filter has a thicker outer shell to provide higher burst pressure resistance during cold temperature conditions and greater fatigue strength. Failing to use this filter could result in external oil leaks due to gasket blowout or wrench flute cracks. Any time an oil filter is changed on one of the above vehicles, it is recommended to use the new and improved filter.

Bypass spring pressure has nothing to do with oil pressure. It has to do with the pressure drop over the filter media.

Oh boy. What they meant to say was clearances. Tolerances are "the acceptable deviation from a specification", and have nothing to do with anything being discussed here. The clearances, HOT are the same as they have been for about 120 years. Cold has changed some. Example might be the use of hypereutectic pistons. They have a much tighter cold fit but the same hot running clearance as a forged racing piston. Bearing clearances are pretty standard at a thou per inch of bearing diameter. Finishes are finer and the leading reason for the ability to spec a thinner lubricant. The only down side to running a slightly thicker oil is drag. It cost you some fuel. 

 

In general people seem to believe that the viscosity on the label is what that viscosity will be in the motor. Far from true. Viscosity is a function of HEAT not rhetoric on a label or in a document. Film thickness a function of viscosity, velocity and load. Stribeck Curve???  Again this hasn't changed since God created the laws of the universe and never will. The results that draw the curve based on those equations have been pushed a bit by finishes. But not enough to reinvent lubrication.
