2021 TB. Is manual or oil filter wrong?

[5of45]

Hello all. 
Recently got a 2021 Trail Boss with the 5.3 .
My manual clearly states to use a PF63E oil filter.  However the filter on my truck (original filter- brand new truck) is marked as PF63. Just PF63... no E.

I tried to search the topic here and found a lot of discussion about the e cores and other filters.  But have they changed specs?  I thought PF63 had the wrong bypass setting for the new 5.3 trucks?

 

I plan to go with a different brand filter from here on, but should I cross reference from PF63E or PF63?

If I remember correctly, the AC Delco filters were notorious for leaking at the seal and the oil filter seal was redesigned somewhat to correct the measure. 

 

Either way, your better served by going to a different oil filter.  Don't misunderstand me, the AC Delco will serve the purpose intended by the manufacturer, but other filters far surpass it in filtration abilities and will do a better job above and beyond that of OEM specifications.  Remember, OEM specifications are a MINIMUM, meaning the factory filter is meeting a MINIMUM standard and will easily be outperformed by filters being held to a higher standard.

I don't understand why GM does what it does but you can run either one.  I can't find the information but I want to say I read somewhere that GM was going back to just the PF63.  

 

I have used both with no issues on several vehicles.   Two different Chevy Traverse's, Silverado's and Suburbans.  I bought a case of PF63E off ebay for $40 a while back which worked out to be a little over $3.00 a filter.

Lots of oil filter choices. I would go with Wix or WixXP.

Also, just incase you were unaware and doing the oil change yourself, one of the main culprits for a leaky oil filter is improper lubrication of the seal prior to installation.  Put a dab of oil on your finger and run it along the seal surface of the filter prior to installing.  It will assist with a proper mating surface and keep a potentially dry seal from stretching or tearing resulting in leaks.

PF63 has 12 psi bypass spring

PF63E a 22 psi bypass spring

 

The PF63E was the replacement for the PF63 after the first year of the Ecotec3 engine cycle, 2015. This was done to prevent unfiltered oil reaching the VLOM improving protection for the AFM lifters. For whatever reason GM, or is it gm, is still using NOS filters on new trucks. Working off stock? Perhaps but the E (the manual) is correct.

Thank you folks.

 

Im not sure either why GM would specify one filter in the manual and not have it on the truck... Especially if it has a different rated bypass spring.  But that’s what they did.  Now that it’s 2000 miles in, I guess I’m going to change to a filter I know is correct.

I just contacted a friend of mine that works at a Chevrolet dealership in the parts department.  He said that GM has dropped the E and now it is just the PF63 filter that they are getting in.

Now that is interesting!

Might be GM's method to clear out stock of old filters?

Why play the game with GM. I would buy another brand.

I use the PF63E.  Dealers around me only tried to sell me the PF63 after telling them GM has a different spec for the bypass valve they told me they could order the E. I had same problem with my Impala, and I offered to show them the GM service bulletin saying not to replace the E filter with a regular one because of the high oil pressure of the motor will cause the filter to open the bypass valve and over time this unfiltered oil will damage the engine. They parts guys seem to think what ever they say is right and don't care about GM putting out info trying to stop dealers from using wrong filters. They didn't care that GM said not to use the filter they had in stock and were trying to sell me. So I would use whats in the manual PF63E. I honestly wonder how many if these motors with early failure or oil consumption issues are caused by dealers using wrong filter?

 

To the guy saying they dropped the E version of the filter. I'm sure they would have to put a service bulletin out so customers would know its OK. My tuck was made this year and still calls for the E filter.

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)

I'm the guy that said they dropped the "E", the part numbers changed a few months ago on most oil filters dropping the "E" designation. The internals of the filter are the same. There was/is no TSB on it, we get answerbacks from GM telling us about number changes and letting us dealers know that a part number is changing, most of the time it does not involve a TSB.

Also, we go by the long 8-digit GM part number, not the short AC-Delco number, the newest 63 filter is GM part# 12707246
