Yep! Oil analysis is the way to go. I used to work for Page Industries at
Ft. Rucker, AL who had maintenance contract with the Army to maintain their
flying machines of all kinds. Oil Analysis was part of it. The oil leab got
so we could predict engine failure and tranmission failure 80%of the time,
sometimes 85 %. That accuracy meant and means a lot to guys whose very
lives depends on it. The info we provided went to Vietnam and I've no doubt
it saved a lot of guys from going down in the jungle.
Oil Analysis Rules!
