Okay so this is maddening. 
 

The 6.6 gas calls for a ACD PF63E. Simple right? No. 
 

it looks like while I’ve been researching that the 63e was made to replace the 63 because it has the 22psi bypass vs the 12psi. Okay seems fine. But it looks like you can’t really find the 63e and that they renamed it back to the 63???!!!

 

so how does a guy know if he’s getting the old 63 or the new 22psi 63(e)?

 

also, when checking other brands I noticed Wix has updated their old number of 10575 to 10255, which has the 22psi bypass. 
 

other brands like fram ultra have the old 10575 still. 
 

so what do you guys run and is the above info correct?

 

thanks

Some interesting info here.  A picture of the old AMSOIL EaO20 filter on the left and the updated Ea15k20 on the right.  Grumpy, you should like this.  Look at the micron on each box.

GM just dropped the E designation on it but its still the same filter as the PF-63E, 22psi.

PF-2232 stays for 01-19.  Its the 2020+up L5P with the PF-26 that the new interchange applies to.  All 2023+forward trucks off the assembly line will have a PF-63 on them.

Ifs it’s a warranty concern buy it at the dealership asking those questions and save the receipt. I’ve gotten in the habit of using the dealer while under warranty.

The PF-63E is a cheap filter.  I would use a Wix XP or Fram Ultra Or Grumpy Bear's recommendations above.

I always change my own oil but I do see the first change and tire rotation is on GM but I’m not waiting until 7500 mi for the first change so I’ll be doing one between now and 1k miles so just figuring out the way to go. 
 

I know the first service has to be within 12mo. Will they do it whenever the customer wants?

 

as for filters, I believe the old pn of 10575 for any brand will only have the 12psi bypass. Wix I know for sure has updated theirs.

Mostly doesn't matter. Change your air filter more often than recommended and the lower fuels dilution of the engine oil will do more for directional improvement to oil and engine condition. Oil filters on our modern GM engines are screen door on a submarine efficient and mostly insurance for stopping a large damaging particle from cleaning out the engine.

How often do you guys replace air filter?

PF63 P/n 12707246

Use the part number which is 12707246 it is confusing I know.  Also the list from Grumpy is a good one to follow as well.  I change my air filter every 10 to 15k miles.

16-28 psig for this XG10575. 

 

Two basic types of bypass springs. Coil which is pretty precise. and the spring steel sheet which gives a wider range. The Purolator PL uses a coil the FRAM XG uses the spring steel sheet.

The PF63E was the old 'E-Core' filter, it has been superceded by the PF63.  The PF63 is improved over the PF63E, but both have the 22 psi relief valve.

 

The 'Gen. V' V-8's always required an oil filter with a 22 psi relief valve.  The confusion came from the 3.6L V-6's and some of the Ecotech 4 cylinders that originally came with PF48 oil filters (15 psi relief valve) which were changed to the PF 63 and PF64.

 

I don't think the PF63 fits the Duramax.

      Missing thrust bearing? And oil selection

      By Black02Silverado · Posted

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      So, lot's of googling and reading, and a trial fit found, that indeed they hit the newer fatter caliper. I did some re-testing today, and found just 3/16" worth of washers was enough for the wheel to spin freely. I added 2 more on each, and again it spun freely. Tested lock to lock with the 4 washers, about 5/16" not quite the 3/8" Im considering, but pretty close. No issues. I've been looking at the BORA .375" spacers and using extended lugnuts to get back lost thread due to the spacer. All the ET lugs I've seen are all .33" reach inside the wheel lug holes. For those that don't like spacers or think they're unsafe, I think it depends on what type of spacers you're using and making sure you get good quality hubcentric ones, and if you're using bolt on ones, regular mainenance, checking the spacer lugs. Not wanting or needing that much spread. Looking for the minimum that will let me run these rims and tires.  it does look to stick out a little, but I really want put these on. and use the stock all-terrains in the winter.
