Karl, According to the original "Service Data Handbook" that came in my 1940 Ford, the Ford Motor company recommends that the crankcase oil be changed
every 2,000 miles. If equipped with an oil filter, "it is recommended that the oil be changed at 5,000 mile intervals except for seasonal changes. The filter unit should be replaced every 10,000 miles." End of quote.
So your statement was off by a factor of 10! I would never have guessed that Ford recommended such long intervals.
