I fly my bird about 50 hours per year. I was taught by an old-timer
that 50 hours was fine for oil changes and that a year was an
acceptable calendar period.

The general recommendation for the average ContiLycosaurus is 25
hours if you have no filter, or 50 hrs. if you have one. I remember
reading a Lyc. manual or tech document that recommended a maximum of 4
months between changes. Presumably, this was to get rid of the
build-up of acids in the oil that are a byproduct of combustion.

I saw a Lycoming recommendation for the O-320 to change the oil at 50
hours or four months, whichever comes first. I think it's in the manual
for my engine.
