I believe that at some point, Packard changed the oil capacity specification for the 120 engines from 7 quarts to 6 quarts. I came across that information in a monthly service bulletin in the literature archive on this website.

The change was not related to the presence or absence of an oil filter.

I would assume that adding an oil filter would require an additional quart, but that may be where the confusion over published oil capacity came from.

I don't recall seeing 8 quarts specified for the 120.

It may be that 7 quarts was needed for a new or rebuilt engine, and 6 quarts for a refill following a routine oil change.
