Exactly. All toilet paper & paper towels are now septic safe & RV safe. They have been for several years. But back in the 50s & 60s when I remember the toilet paper filters toilet paper was not so easy to dissolve.

 

Paper stays intact in oil.
Even modern paper.
This is a non issue.

 

Interesting filter the Frantz. We had them on a lot of military vehicles, generators and pumps from small 4 cylinder Diesels, to huge Waukesha's and even many gas turbine generators. They were phenomenal at pulling dirt from oil. You could run stuff in as black as coal and it would come out golden brown.
Then suddenly we were told to remove them from any troop carrying trucks, then all gas turbines. Eventually they were removed off of everything and scrapped.
I did not see the direct reports but scuttlebutt at the time said that the filters were so good that they were pulling out the zinc and other antiwear additives which was causing bearing failures.
Oh yeah. This was in 1971.

I'd like to get hold of some of these filter housings so I could recycle some of my drain oils for use in my other equipment (mixing in a little STP)..

 

I have had to sit on my hands for the past 2 months with this thread, but I finally got the go ahead to post in here. Our company (Lubrication Specialties) has taken over the Frantz Filter company and operations. We are updating a re-releasing the Frantz Filter, and the first orders will be going out in the coming weeks. If you want to check it out, go to frantzfilters.com
