Filter? We don't need no stinking filter! (Older Guzzis have none).

Neither did my '66 Cessna 150 have a filter. Continental said dump the oil every 25 hours. If I had an oil filter the interval was extended to 50 hours. I'd rather change every 50 hours. That's close enough to 2,500 miles to seem reasonable.

too bad that he did not include centrifugal type filters.

W120 a 60 sae aero oil which I used to use in Pratt and Whitbey R2000 radials actually had a life of 100 hours, the oil filter on the R2000 was pretty good at stopping large rocks the occassional small child and about half the metal from a big end bearing failure.
So 50 hrs is a very conservative change interval, but Ill bet the Cessna didnt carry 20 us gals per engine.
