what has happened to oil filter part numbers
Go to the parts store yesterday to get an oil filter. Looking through the books I can't recognize any of the AC, Fram or Purolator numbers. I pull the filter they show for my 70 Z28 and it is only about 2 1/2" in height - (the number is 454 or close). The best we can find is a AC 1218 for a late model truck that seems close. What are the correct part numbers for the full size filter for small and big chevys? They are saying the good old PF 25 and 35 are goners.

The Chinese, who make everything now, including oil filters, demanded that the part numbering system be changed. So it was changed. I'd recommend you start liking it. Seriously, you better start liking it. We wouldn't want anything "unfortunate" to happen to you.

The one I just recently used is a PF454, formerly PF25. It is quite short, but it sure makes getting the filter past the headers easy.  |

If they don't have the long truck filter then get it at GM. GM's PF #'s have changed too. Thanks GM for making it in the USA and Canada. NOT!!!
And you wonder why people are out of jobs here.

I tried to order some new Amsoil filters the other day and the dealer told me the number I had been using was not in the order book. Been using that one for years (EAO76) and he says he can't ever remember that number being used. I know all their filters are made in the Us, wonder why the part number is not there any more. Still waiting to hear from their support people.

The PF1218 isn't a good choice to replace the PF35 on our old cars. They are the same size filter, but the PF1218 has an antidrainback valve that serves no purpose on an old Chevy small block except to restrict oil flow. If you can't get the PF35 from GM, look to a different manufacturer who makes two different number replacements. One with the anti drainback valve to replace the PF1218, and a different one without the valve that directly replaces the PF35.
As far as the PF454 being a replacement for the PF25, there seem to be even bigger problems there. Read this thread on the Corvette forum.
The size doesn't appear to be correct, and can lead to failure.

Again, your best choice today is to forget using AC Delco filters on old engines. Get a filter from a reputable manufacturer like Purolator, Wix, Hastings, or Baldwin. And, make sure it is a DIRECT replacement for the PF25 or PF35, not a one-size-fits-all like GM sells. |

I just checked Amsoil's site and the cross they came up with for the PF35 is EAO27. Also, they show the cross for a PF25 is EAO25.
I just got their magazine in the mail yesterday, and it has an article about their filters. They have redesigned them for increased capacity and filtering. Maybe that has also made for some numbering confusion. |

they are changing the filters making them smaller and more compact for the same application so our 5 qt engines are actually 4.8 qt
