Thats a debate thats been going on here for a long time.
I’ve heard (thru the internet) that the factory offered this option to filter out any particles during the engine’s initial break in period. This makes sense and also a good selling point for this option. It also is a consumable item needed during oil changes. This would make them some extra money. No facts to back this up but it is a rumor I read somewhere in cyberspace.
Seriously, as long as you change oil on a regular basis, once or twice a year, 3k or less, you should be fine running without filter.
Edit: By the way, I run one on my ‘59 235. It came with it, I thought it looked cool, so I kept it!
