A Franz filter will not give you modern filtration. The Franz is a bypass filter. Only some of the oil is filtered at any time and over time, all of the oil is filtered.

The boys I ran with used Amsoil and never changed their oil. Every 3k, they replaced the Franz filter and added a quart. Right or wrong, those fellows never lost an engine due to oiling issues.
