Off my 3mz Highlander, currently on its first full run of HPL 5w30 pcmo. Previously ran ec30 and found essentially no carbon https://bobistheoilguy.com/forums/threads/champ-xl-ph2835xl-cnp.386207/#post-6981049
So I think this motor is pretty clean. I did valve cover gaskets about 4 years ago shortly after buying it and it was pretty decent looking inside. There was some tiny flakes of carbon but not much. Pretty evenly spread out. Should have no problems doing a long run on the new filter.
Regardless, this filter looks like a million bucks to me. Disturbingly straight pleats. Quality construction! Was replaced with another s241 unit that will stay on until I hit 180k (was put on at 173,956mi)
