My 74mm oil filter wrench always worked on whatever filter I used on my Saturn. First AC Delco PF61, then Wix 51522. Last Wix filters I got looked different top to bottom, like somebody else makes them now. They had 14 flutes/flat spots, the ones before had 15. Now my wrench won’t fit. I just got AC Delco UPF61R thinking they may still have 15. They have 14 also. When did this change?
