I always used FL1A, my 78 owners manual spec's FL-1, with 5 qts oil. However, every other resource (including Ford) seems to specify the short filter, Motorcraft FL-300.
I know either will work, wondered if there is some advantage to the FL-300 (other than clearance). Maybe better flow? The FL-300 is 1" shorter, so holds about 1/3 qt less.
What is everyone using?
Thanks!
