The best thing oil analysis does is catch fuel, glycol and dust problems before they become a problem.
It's less and less these days about "what's the best oil"
Unfortunately oil analysis doesn't catch catastrophic failures.
Parts can just fail, and it's crap when they do, but it will tell you if, for example a bearing is on the way out.
Which one it is, eg. cam, big end, little end, rocker bush or main is another question.....
