Usefulness of Oil Analysis

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?

Oil analysis is a very usefull tool for showing the status of the
inner workings of the motor. Your first sample will give you instant
results if there is something major failing, based on thousands of
other samples of like engines. At about the third sampling of your
perticular engine trends will develop showing the state of your
powerplant. Oil analysis is a inexpensive way to keep you safe, and at
about 15 bucks a shot a great value in aviation. Do it today....

Jim, I am part of the "Choir" here...

I have 2 large marine engines and one aircraft engine. (all 3 are
$$$$$)

And.....

I depend on them !!!

I have used oil analysis for 25 years,- boat, heavy trucks, and now
on the plane.

Cheap "peace of mind cost".

It WILL turn up some problems in time for a minor fix, before it
becomes a catastrophic failure.

It will take about 3 tests to set a "normal" baseline for your engine
(s). After that, sudden changes are quickly detected.

We tore down an exhaust system last week, confident the antifreeze
leak was not in the block because if it was, the coolant would have
been detected in the oil. (there was none)


It is part of knowing you have taken EVERY reasonable precaution to
insure your safety flying behind that engine.

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.

If I hadn't been doing an oil analysis I wouldnt have known to look
for a busted up piston pin plug.

How about a URL or contact info. www.metalcheck.com apparently isn't the
right place.

Who do you use for your aircraft engine?

Robert,

For educational purposes could you please describe all of the indications
that helped you pinpoint the problem you found..
