After getting a lot of good information and feedback here I switched to the Microgard Extended oil filter for my 2024 motorhome (Ford E450 - 7.3l Godzilla V8). Very happy with the quality of the Microgard. After I took the Fram off I drained it out and cut the top off the filter. I don't have a fancy oil filter cutter so the Dremel tool got it done. I was curious if the filter had the ripples everyone is talking about in the leaf at the bottom of the filter. Took it apart and cleaned up the leaf. It looks flat to me, no visible ripples or any that I could feel. I put the leaf up against the bottom of the filter element and it sat flat without any voids that I could see with my naked eye. Maybe I got lucky or maybe Fram got their act together. This filter went on the vehicle in September 2024, purchased from Walmart so I don't know how long it sat on the shelf.
