Sorry you had that issue with the fram. I don't use them for other reasons, but that is good enough reason. I like your idea of taking the spare stud to the store and trying different filters. Let us know if you come up with a new one to try. I am currently using the Mobil 1 M1-108 with no issues.
You need the "A" on the end of 6018..that is the course thread that is REQUIRED..frame is a poor filter anyway.
