Oil filter confusion

[Jimbeau]

1st oil change. 2023 Sierra 5.3

Decided to change myself instead of taking to the dealership for the free oil change.
Went to purchase Mobile1 Dexos1 oil and filter. Filter type: STP Extended Life part number S10590XL. I noticed they have 2 sizes with the same exact P/N (see pic). One of which is about an inch longer than the other. Removed them from the boxes and sure enough one is longer. Used the cross reference book to check out other brand options. I found quite a mix of long verses short options that all show to fit my 5.3 engine.

I assume the long one is better but want to make certain I have this correct. Of course the parts guy had no idea.
I searched the forum and found some mention of bypass pressure differences which only added to my concerns. 

 

Thank you.

Being your still under warranty I would stick to the original AC oil filter which I did and still do even though iam out of warranty on my 2019 due to the fact if something would happen to the motor under warranty they can't blame it on the aftermarket oil filter. Also save your receipt and write the mileage on the receipt incase something would happen you have proof you changed the oil. Don't forget to reset the OLM.

Not sure what the story is on the STP filter. In light of the confusion I would look at a different brand. The AC PF63 is the filter for your truck but youre under no obligation to use an AC filter to maintain your warranty. If youre buying your filter at A-Z youre paying too much. Walmart had a much better selection for less $$. Around here the Chevy dealer sells AC filters for less than Walmart.

Well I just picked up a PF63 at Walmart but the confusion between short and long is mind boggling, especially being the same part numbers. I sent an email to STP requesting clarification.

Perhaps one is a copy of PF26 and the other PF63? 

 

A couple years ago, GM changed the recommendation for several applications from PF26 to PF63. 

They indicate that PF63 is preferred but that PF26 is acceptable when PF63 is not available.

 

 

 

The PF63 filter is 3/4 inches (19 mm) narrower than the PF26 filter, but it has a taller pleat height, which maximizes volume efficiency and cold flow performance. (Fig. 7)

Service Information and the Parts Catalog will be updated shortly. For more information and part numbers, refer to #PIP5870. 

 

 

I generally use Delco filters, but I don't buy them at a dealer.

 

'Free' oil change is really a 'pre-paid' oil change.

Might as well make use of it. 

Doesn't have to be at the dealer that sold the vehicle.

That’s good info and seems to reason. I’ll post the response from STP if they answer my email.

I would not use the S10590 or S10590XL filter.  The bypass pressure is too low and set to the original PF48 spec of 12-15psi (same as the PF48).  The PF63 is 22psi.  They bumped this due to the tighter oil passages and oil pump operations.  

 

TSB on PF63 applications - temp.xml (nhtsa.gov)

 

AC Delco PF63 or UPF63R are the factory filters you can get, Mobil 1 M1-212, Motorcraft FL500S or Wix WL10255 are some good picks also.

Thanks. I went with a PF63 off the shelf at Walmart and will continue to use this filter in the future. How do we know if this is the current PF63? Have the original PF63s been discontinued?

I have revised my above post slightly.  The PF63 is 22psi bypass from day one, my error was stating it was lower initially.  The PF48 which was on the early 3.6 V6 engines was replaced by the PF63 due to the oil pump changes and oil galley changes which required that PSI bump.  The 2014-up V8 truck engines got the PF63 due to their changes as well from the Gen 4 small blocks prior which used the PF48.  

 

All PF63 and proper crossed filters should be good but verify the bypass PSI still.  The three I listed are spec'd at 22psi bypass, from all the data I found on the STP its 15psi unless they haven't updated that information.

Great thank you.  I’m sticking with stock after seeing the variations.

STC responded to my email: Now I’m even more confident about not using their product. 
 

my email:

I’m confused About your S10590XL filter. Tried to purchase two of them and realized theres 2 versions with the same exact part number. One is about an inch longer than the other. Please Explain?

 

Response: 
Thank you for contacting STP.  Regarding your inquiry, Kindly note that the Oil Filter is a licensed product by AutoZone. Please contact AutoZone to get further assistance. We have provided their contact information below.

 

Wow. Glad I went with a legit PF63 instead is dealing with the A..Z BS

I know that the actual GM part number has changed, but my 2019 show the actual part number as 19330000.

 

It's confusing since PF-63 is the general number, but if you can find the part number listed in your owners manual, GM updates the filter often it seems and so do a search for the actual part number filter.

 

As for the STP filter, it's not a bad filter, but like others have posted, Walmart has the better price and also sometimes the dealer will have it, just depends on your location.

 

The AMSOIL filter is the EaO17, which I run on our Suburban and my Silverado.

UPF63R only in my vehicles. I get mine from Rock Auto. 

[Jimbeau]

What the heck is the deal with AC Delco part numbers?  For the PF63 I’ve found 3 different part numbers. 
My 2023 5.3 manual says to use GM part number 12707246.

I’ve found 2 other GM part numbers for a PF63. 12735811 and 12731742. See pics.
