Re: '54 oil filtration question...

The bypass filter is more effective than the full flow in that it filters finer. With the correct element the oil will stay clean looking on the dip stick until the filter clogs up.

They did not want to take too much oil away from the engine and could not force very much through the fine filter so they restricted the flow.

The newer theory is to filter all the oil thru a coarser filter and let the fine dirt soot and grit go through the engine. Supposedly there is enough clearance between the parts to let fine dirt go through without doing any harm.

Any filter is better than no filter at all.
