Came off of my 60k mile 2018 Sonata with the Theta II marshmallow engine. Filter has 4k miles on it, topped off with a BG EPR service to help correct some minor oil consumption. Filter is remarkably unremarkable; no excessive pleat spacing or other issues that I could see. Partsmaster 5w40 full syn HD oil and a Napa Gold 1334 went back in/on this time around, but will definitely use more of these in the future.
