If your Walmart is anything like our Walmart, filters have to be opened and inspected at the store before buying it. It wouldn't surprise me one bit if that filter wasn't manhandled and placed back in the box. I've seen them torn, and Orange Can filters stuffed in Ultra boxes, along with a slew of other things. With regard to contacting Fram, absolutely, or return it to Walmart grab another and inspect it in the store before taking it home.
Please keep us updated on how Walmart responds. They inspect the box at purchase and likely will inspect the entire filter when you return it.
Because there's marks and darker areas on it now, lets see if they give you a store credit or replacement. I'm guessing they will.
Did the metal backing, as well as media, pull out of the end cap easily? What's the date on it? Not recent, I hope!
This is at least the 3rd report on BitOG of serious problems with the XG10358. Also, as of two or three years ago, most of the ones I looked at in Walmarts had absurdly uneven pleat spacing. There's no point in including the theoretically optimum number of pleats, if half of them are crammed tightly together in only a third of the circumference. However, the ones I've seen more recently look OK in that regard, and so does the one in this thread.
That's in contrast to the Chinese TG10358. All of them I've seen look beautiful, and the one I bought was trouble-free for 25.8k miles of use.
Recent XG3980 20k from Amazon I bought has sealed box bottom, glued. Older one 15k bottom not sealed. Why can't it be what it very likely is, without excuses or imagined events,, an Ultra with a defect. I never, ever, had a checker open an oil filter box on purchase, and also can use self check out. I even told a checker there is a problem with switching filters. She could care less.
