oil filters

This started way back in the early 70's for me. The Wix guy came in. We stocked some Wix and some Hastings. He actually went to different stores in town, back then, K Mart I think had Fram, and bought AC, Motorcraft, Fram, and ?? what else. Took a cutter and cut them all open

Some differences you cannot see, the micron rating of the paper, example.

But to this day I remember this, and it was 35-40 years ago!!!!

The Fram had obviously less filter material. AND it had cardboard ends on the filter where it went into the can

The AC had metal ends but it had a VERY small paper element.

Hastings at that time did not use a paper element. They use "media" not sure how to describe what it is

I don't remember much else. These were all the same filter, either PH-8 equiv or the popular Chev filter, so they were "all the same."
