Last time I was in there the STP XL in the shelf was a PG made filter. Almost identical to the Oreilly Microgard Select.
Microgard Select - No Love?

The construction appears quality the only thing that concerns me with these house brand filters is who do you contact if you need to file a warranty claim? With Fram, Wix, AC Delco it's more clear and I would know who to contact. I checked and there's little information at AutoZone. If u go to STP website there is not much info on oil filters, but I think they just license the name

I wasn't that thrilled with it. Metal shavings came off the threads and ended up on my magnetic drain plug. Also never had an oil filter rust like this. Very much hoping my engine is okay.
I'm going back to OEM.
Metal shaving at the tip of my thumb.

Oreilly Microguard Select is an excellent filter. I'd be happy to use one.
However, NAPA Gold is slightly better as shown in an online side-by-side filter dissection Youtube video of the two. I don't have the link, but you can Google it.

I've never seen a rusty filter before (and I live in a rain forest). Huh.
How do you know where the metal shaving came from?
Surface rust on unpainted crimp is a non issue. Metal shavings would be from the threads. Inspection before installation is a must on every brand.

How would a person know after the fact where a metal shaving came from?
True.
I should have worded it as “I’ve seen metal shavings from thread cutting on many different filters over the years.”

I visually inspected the Oreilly Microgard and NAPA Gold filters I bought. I did not see any metal shavings nor other issues. That said, visually checking is a good idea because it could happen with any brand of filter.
Yes. PGI made filters and Pentius filters have the most consistent quality currently. Very very rarely do I see problems.
They couldn't. Everything seen on a magnetic drain plug is pretty much a mystery of where it actually came from.

I thought so. I'm trying to make a point by asking the question. I assumed the answer would be as you and others have stated. Hopefully the OP sees the point I'm making.
There's no way he could know if the metal flake came from the filter threads because he didn't check the threads before installing filter. So I don't think it's accurate to assume the filter is the source of the flake.

My apologies, I didn't take photos, but there were some similar flakes around the threads of the filter itself, and if you zoom in on the photo, you can see a scalloped area of the threads still on their filter.
To each their own. I wasn't overally impressed. I live in the Northeast, and in 20 years of changing oil I have never seen the rust or the thread issue. Could be one bad batch of tap from PG.

This thread flake topic me thinking. Seems like maybe it'd be a good idea to have a properly threaded pipe or bolt that every new filter could be threaded onto and off of prior to installing filter to help remove any partially attached flakes. Would that be a good idea?
The replacement in the background said you were not.

I put it back in the box. I might try to take it back for store credit. I noticed some oddities there in the threads too.
This is for my truck. I noticed the shorter version of this filter my wife's car uses the threads look fine.

Listen, I've been a member on forums for cars and other topics since they were basically a thing. I know I'm going to get raked over the coals here.
Why? Well a lot of you are already emotionally invested in having chosen premium guard family of filters as your go-to. You'll find every reason to doubt it.
And maybe you are right. My engine that's seen 3,000k mile oil changes with OEM filters and Valvoline or Mobil 1 could have randomly gotten a metal shard from somewhere, even though I've never seen an oil filter with scalloped threads like that before, or had metal shards in my oil for 41,000 of owning this vehicle.
It's just an anecdotal experience. Take it exactly for that. Carry on.

No one is raking you over any coals. There are no coals in this thread. I questioned why you thought the metal piece was from the filter because you initially didn't explain your reasoning. After your further explanation, I don't doubt you.
I've never seen a rusty filter even though I live in a wet climate, but we don't salt the roads here. I can see from your photos that rusty filters are an issue for you with multiple brands of filters. I assume the roads in your area get salted in winter?
We're not emotionally invested in an inanimate object. Please give us more credit/respect than to assume that about us. We genuinely care about these issues and about your situation too.
So far I've been having good experiences with Oreilly Microgard Select and NAPA Gold (they're siblings). So have many others. I'm sorry it didn't work out for you.
You said you prefer OEM filter. Do you mean AC Delco? I wonder who makes it. Purolator maybe? I wonder if it has more rust resistant metal or better paint?
Perhaps you should paint your new filters with a highly rust resistant paint. It you really want no rust ever... Buy a quart of POR15 and use a paint brush to apply. Then no rust for sure.
POR15 is the same black paint that ocean going steel ships use. They apply 3 coats below the waterline, which is the black paint below waterline. Above the water line they apply 1 coat as primer. Then paint their preferred color of marine paint over that. Shipping companies buy 50 gallon barrels of it. You can buy 1 quart.
