A truly outstanding article, but I tripped over...

Full-flow oil filtration was the hands-down
winner, reducing some types of wear by as much as 600%.

I can type over 100wpm. Oft times that's faster than I can
think :-) (I was trying to type '...as much as 60%.')

A few of the actual figures cited were 66% for wrist-pin wear, 50% for
crankshaft wear, 19% reduction of cylinder wall wear, 52% for piston
ring wear...

Some years ago I spoke with a fellow who retired from Fords that
remembered the project. He said it actually started in 1940 but was
put aside when the engineers were assigned to war-time projects. It
was taken up again following WWII but the test engines were only run
on a 9-to-5 basis, five days a week.
