I have been using Metal Check and the results are always about the

did not help predict the problem.

Any real life stories?

Well, it didn't result in any engine work, but I did have an analysis that
showed high levels of silicon. The interpretation was that I needed to
change my air filter. I know change the air filter every 100 hours
(instead of at annual as I did when I was not flying as much), and I've had
not more dirt in the oil.
