My filter guy that supplies me with my oil filters (Wix) dropped off a new purolator classic oil filter L10111 Date Code Fo1G 12B1 Because he was out of the wix in that number and we needed one in a pinch. We decided not to use it anyway. We went and got an ac delco non e-core and installed that. I want to cut the new purolator open and see how things look does anyone know what date and year this filter was made?
