Why not use a Purolator oil filter instead?

Gotcha, so if the filter is obviously not a GM even if it is of a correct size and color - it matters for not - zero points. But the wrong color and size of the GM part would muster a point. Appreciate the insights.

What about a plain white filter of the correct size? No brand markings whatsoever - as generic as they come so to speak?

thanks,

Real PF-25 = full points.
GM service replacement or good reproduction = partial points.
Aftermarket brand = 0 points.
It's like "speed" - points cost money, how many points do you want?

Isn't an aftermarket just a 'bad' reproduction? And some aftermarket filters like Purolator may be better in that they are white and of the correct size.

W/ respect to an original correct 'white' PF-25 == full points...

What about a 'blue' PF-25 or a PF-454 or a 'generic' white filter of the correct size but lacking in correct markings? How do think they stack of John?

thanks,

To amplify on John's post in an effort to answer your questions:

Aftermarket brand = 0 points, regardless of its shape or color or manufacturer so long as it is other than AC Delco or its successor companies.
Service replacement, manufactured by AC Delco or its successor companies = partial points. What part of the points depends on its shape, finish, etc. In my opinion, a blue PF25 would get more points than a PF454, but I have to qualify that by stating that I have not seen a PF454 yet. I am basing my opinion on the comments of others regarding its size.

Thanks - understand on the service replacements.

What about a partial or innaccurate reproduction scenario? - let's say you manage to reproduce one of the correct size and correct edges and so forth in the correct shade of white. But you don't have a way to reproduce the logo or markings. E.g. it's left plain white. The brand is ambiguous - is it aftermarket or imperfect reproduction? Other than the lack of "AC" markings in red and such - would it not fare reasonably well otherwise in judging and perhaps better than a service replacement?

This doesn't have to focus in specifically on oil filters but the example could be applied elsewhere - this scenario just happens to fit.

I've got a dumb question...

Was the oil filter installed when the engine was painted? If so, then a filter painted to match the cylinder block color should also be acceptable.

Re: Why not use a Purolator oil filter instead? *TL*

We had just such a discussion at one of the Advanced Judging Schools at Welches, OR, last weekend. Increasingly, parts that come in AC Delco (or Delphi) boxes have no identification that ties them to those companies once they are installed on the car. In many cases they are no longer made by those companies and are thus identical to parts purchased from "aftermarket" suppliers.
There were a variety of opinions on how to judge those parts, and there are strong arguments for either of two positions.
1) It is not made by AC Delco or Delphi so it merits Zero points.
2) It came in a AC Delco or Delphi box and so should be judged based on the degree of difference from the original factory installed piece.
As an aside, I should point out that sometimes even if one takes the point of view put forth in #2 the result is zero points. There is sometimes no resemblance between the original part and the currently available part.
We reached no firm conclusion at that school.

Re: I've got a dumb question...

When the engine was assembled in the engine plant, a plate was installed over the oil filter opening on the engine block. The partial engine was painted, assembled, oil added, engine tested and shipped to the assembly plant. On the engine dress line in the assembly plant, they installed the oil filter. There should be no engine paint on the oil filter.
