Dennis,
You are dead on about this oil. testing.
Years ago I worked in an oil analysis laboratory that was run by Page
Industries for the US Army helicopter Training Command at Ft. Rucker,
AL. The lab took in oil samples from aircraft engine, helicopter
engines, and helicopter transmissions. We cataloged the samples, and ran
them through a spectrometer to gather data and then plotted the results
for each sample to the appropriate engine/transmission. Before I left
the lab, we had gotten our /engine/transmission failure prediction rate
up to a little over 80% and it was steadily improving. With this data,
preventive maintenance was improved, catastrophic parts failure was
avoided, and potentially lives save, plus we saved the government a lot
of money.
I believe in that oil analysis. Because of my driving habits today, I
don't do it, but I believe in it, none the less. It all boils down to
how tight you want to stay on top of your machinery and it's issues.
