Thanks for the info. And, that is some wonderfully deceptive corporate jargon.
I have a couple FE7317’s (purchased this week) that just say “Fully Synthetic media’ on the box. Nothing about a blend. No * leading you to fine print on the box. Nothing.
Maybe I got some rare FE cans that are stuffed with fully synthetic, non-blended media, and I’m sitting on a gold mine.
I’m sure the filters are perfectly fine for the intervals stated by the mfr. But, that makes the deception even more puzzling.
Is there a wire backed, 100% synthetic media filter on the market regardless of price for applications requiring the 7317 sized filter?
