Are oil filters necessary on mid 50's trucks

I've read that only a small portion of the oil gets filtered. I've read anywhere from 7-12 %. But since the oil in the pan is always moving wouldn't all the oil eventually be filtered? If the filter was a option is it really needed as long as you change the oil regularly?

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!

The optional filters are indeed bypass filters, not full flow from the oil pump. Eventually virtually all the oil passes thru the filter, but it would take a while, with only 7-12% each pass.

Just change the oil per the original recommendation, and it'll be fine.

I have one that came on my truck, so I'm putting it back on.

When you use one of these filters the oil on the dipstick looks as clean as it comes out of the can. That has got to be good. Besides it is cool to pull it out & show it to someone like that.
You have to be careful of the lines though. If it is too close to the exhaust it can crack or burn. More engines have been damaged by leaking lines or filters then are saved by the oil filter.

Please correct me, George (or anyone):

It is my understanding that you you should use detergent oil (single-grade or multi-grade) in order to keep "things" in suspension in the oil (so, they can be filtered-out of the oil).

If you engine had/has used non-detergent oil, I think you should remove the oil pan and clean out the "gunk/dirt/grit/etc" at/in the bottom of the pan. Better being safe than being sorry?

I have the oil filter which was mounted on the inner fender well unlike most that I've seen that are mounted on the engine. Steel lines to the block. I'm using fenton headers so I'm not sure if I'll have to reroute the lines. If their close to the headers I'll wrap them with insulation. Freshly rebuilt engine so it makes sense to have it for break in. Tclederman, thanks for the tip on using detergent oil

My oil filter was mounted on the inner fender as well. If your lines are steel all the way to the block, you should put a section of hose in each one to avoid the lines breaking from flexing between engine and the filter. You could route the steel lines against the firewall to avoid the headers.

tclederman As I understand it now non-detergent oil should be used in air compressors to keep down foam,in the olden days when shellx100 came out it was high detergent oil. There was a powerful stink about using it in older engines 'cause they would then drink oil. As higgh compression took over detergent oil found it's place !!

II want to keep the filter in the fender well so I'm going to run high pressure rubber hoses to the to the firewall then back to the block to keep them away from the headers
