A note on bypass oil filters: The original owner's manual that came in my '40 Ford says to change oil every 2,000 miles if no oil filter and every 5,000 miles if equipped with the optional bypass filter. So Ford evidently thought a lot of this filter! Since my car just recently turned 36,000 miles, theoretically it is on only its 7th oil change!
