I always lube the seal with fresh oil I usally fill the new filter about half full then spread it on the seal before I twist it on. The only exception is my mountaineer I can't put oil in it without dumping it out all over me so I just lube the seal and put a tiny bit in the filter. I remember in auto mechanics in trade school they tought us to always put oil in the filter to eliminate dry starts idk that may be a myth but it always stuck with me.
