What I think is funny is younger people think the oil filters with the replaceable filters are new "green" tech to save money and resources. But it is actually old technology that was offered on autos as early as 1950. Certain 396 Impalas had them I know this because Kid Rock's '65 Impala that we worked on at my old job had one. I asked if it was a mod because my Cobalt had that type of setup. My buddy said no, it is factory. Just in case you wanted to know.
