I found this case of Kleener brand oil filters in the attic of my father-in-laws shop. i googled that brand and can’t find any info on them. Can anybody help? Who manufactured them? Thank you for any input.
Can you see the media through the holes? Any chance you want to cut one open? The only reason I ask is that a few early oil filters simply had some cotton wadding for the filtering media. Just curious if these would.
