From those that use it, I'm interested in the usefulness of starting an
oil analysis program on a big bore Continental that already has 850 SMOH
and 450 STOH on an 1100 TBO. Does it take so long to establish a
baseline and trend that it would be better to wait until OH or can an
individual engine be compared to the class as a whole?

If I hadn't been doing an oil analysis I wouldnt have known to look
for a busted up piston pin plug.
