Pf46 Oil Filter

[d6105]

Just picked up a new OEM PF46 oil filter for my Yukon 5.3 and noticed that the filter is slightly different now. Looking online I found a couple things about the filter but I have this uneasy feeling that this change was done out of necessity (cost and urgency) and not necessarily for improvement (see underlined below). Below is a picture I found at the LS1 website showing the differences visually and some additional GM chit chat from a bulletin also. Do you think this filter is as good as the earlier version as it looks and feels cheap? Any comments or insight from anyone who has the real skinny!

 

 

 

Filter Design Change - PF46, PF47, PF52 and PF61 (WD Bulletin 09D-054)

ACDelco is implementing a design change on the PF46, PF47, PF52 and PF61 ACDelco Oil Filters due to

capacity constraints on the current product design. GM engineers have approved the new design which will

begin to be incorporated in upcoming vehicle designs. This OE approved and manufactured filter provides

the same Duraguard filtration performance as the previous design and specifically utilizes the original

ACDelco media that traps particles up to 25 microns. Additional features include a slightly smaller can, fully

covered baseplate, non metallic end caps and high strength nylon core. This newly designed oil filter has

the benefits of not only bringing excellent filtration performance, it is also environmentally friendly with

components that can now be easily separated into steel, oil and parts to incinerate, resulting in less waste.

At this time, the Durapack versions of the alternative design filter will begin shipping. The boxed or

individually packaged versions will utilize the available production capacity on the original design, where

possible, and will otherwise begin to rollover to the new alternative design.

ACDelco appreciates your business and stands behind each and every filter that we distribute with pride

and confidence. Should you have any concerns or questions at all, please feel free to contact your local

ACDelco sales representative.

I think that is the new ecore design. A lot of folks don't like the new design. Personally, I have always used the pureOne or the Napa Gold filter. The napa gold is on sale right now for $4.71. This is a no brainer.

Your good to go!!! We've done many oil changes at the dealership with the newer design filters,no issues with them at all.

[asilverblazer]

Meh, I don't see a big deal. Especially with any kind of reasonable change interval.

[dlstewart01]

It has the same amount of filtering media as the older design. The old design had the anti drain valve in the bottom. On the new Ecore it was moved to the top of the filter freeing up some space.

 

Champion labs made the old one and makes the new one as well. Champion labs makes around 20 different filters to include Mobil 1, K&N and the Royal purple oil filter. They are the largest filter manufacturer in the USA.

 

I have been using them with no issues.

GM OEM AC filters are used on all production vehicles and they are all covered by the 5 yr 100K powertrain warranty. I myself would be reluctant to use anything but AC Delco filters.

[RaddHazzard]

I use strictly ACdelco or Napa gold. Since this new design came out, ive been using the later (latter?) until i hear the good/bad/ugly on this new one.

[BigBlueLB756]

I agree; stick with the blue cans on GM vehicles.

Just found this online from AC Delco News November 09...its like new Coke and Coke Classic - Gm is going to keep the old style filter too because of the number of vehicles using the prior design???

 

Classic Oil Filter Design Reintroduction: PF46, PF47, PF52 & PF61

(WD Bulletin 09D-142)

Earlier this year, ACDelco introduced a new OE filter design for our PF46, PF47, PF52 and PF61 oil filters which has an “E” added to the suffix. This change in filter design was implemented by our OE engineers to be used in production of 2010 vehicles and as a replacement filter for certain out of production applications.

Due to the volume of vehicles that currently exist with the prior design; a decision has been made to reintroduce the original, classic design in the boxed version, for the ACDelco channel only. This will allow consumers who prefer the original design to continue to use it on their vehicles. The filters are identical to the previous design in all aspects and will carry the previous short number, i.e., PF46. The current OE design will continue to be available under the new short number "PF46E" and will carry the current long number.

..well I am glad I ran across this thread....I was in the midst of an oil change on my04 Hoe' today and compared the old filter PF46 to the new one which is slightly smaller...as the photos show. Nervous I called my local dealer parts guy and he said the new one's are out and are just fine...that's what they use now...

 

Personally, I had a bad feeling about the size and the non-metallic end caps....hell that sounds like a Fram filter...I have been using blue cans for a long time and hope it's not coming to an end.....

I wonder what ACDelco Filter is used on the LY2 4.8?

Redvett is right. Why would GM put an inferior oil filter on the trucks and them give you a powertrain warranty of 100,000 miles.

 

I believe they still hire some pretty good engineers who know what they are doing. No need to second guess them.

 

And as far as Wix goes, Some of them have been turning up that are made in China and Mexico.....
