Usefulness of Oil Analysis

Mostly it was Blackstone calling me telling me to check for a broken
pin plug. Any professional oil analysis will come with professional
evaluation of your data. The main indicator for me was progressively
higher AL in the oil.

How about just laying your eyes on the filter at every oil change -
then washing the filter in solvent, filtering the particulates out of
the solvent, and saving them in a plasticine envelope for comparison
to the next change(s)...
Total cost about 2 bucks an oil change - 1 quart of solvent and 1 Mr.
Coffee filter...

And the quart of filtered solvent can be re-used for cleaning the
landing gear...
