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?

When I bought my airplane I started an oil analysis program right away.
I had about 400 hours to go to TBO. ( I was going to go longer, but that
is another story). Then I changed engines and continued the program. I
use Metal Check and get the kits right from the factory. They even now
put the results on the web and can show trend analysis. Something I was
doing on Excel originally.
