Most cars didn't have oil filters until the 1950s. I have a friend with a large collection of cars from the teens through the 50s.
Almost none of them have oil filters , including Cadillacs, Packards , and Duesenbergs. These vehicles are all driven regularly but not as daily drivers. They get their oil changed twice a year.
Unless your engine is shedding metal or operating in severe service, an oil filter is superfluous. Today's modern oils make it even more so.
Would I remove a filter from an engine that already has one? Probably not.
Would I add a filter to an 90 year old engine that never had one to begin with? Probably not.
