hey guy, if analysis says your head gasket is about to go or that your
cam is about to fail, are you going to embark on that 2500 mile road
trip or are you just going to change the oil and pray? do you have aaa?

If it proves it to you, that is fair enough. What is your background of
expertise in
this subject?

But it doesnt prove it to me.

you're not "avoiding an oil change", you're getting a checkup on the
health of the engine. chemical content tells you a lot about how the
motor is running, too hot, too cold, contamination, wear, imminent
failures, etc. if you could predict whether the motor was going to fail
in the next 6 months, and you were planning a major road trip, would you
just go anyway and get the car fixed along the way, or would you get it
done now while you have the time and resources to do the job properly?
you don't wait for a plane's engine to fail in flight [if you can avoid
it!] do you?

The analysis is not really going to tell you your head gasket is 'about' to
go, or that your camshaft is 'about' to fail.

And if your cheapo oil analysis gave you an indication of coolant invasion
or extra wear, do you put enough faith in it that you stop what you are
doing,
tear down the engine and rebuild?

Not likely.

I maintain my cars regularly and don't waste money on an oil analysis to
predict how long I might be able to put off an oil change. (FYI,
I am a professional chemist, and have been for over 40 years.) Chemical
analysis can be interesting, but it does not necessarily predict, or
postpone,
fate.

I have NEVER had an engine failure nor a transmission failure on the road.

Admittedly, I don't normally keep a car with much over 150,000 miles
on it.

Speaking of failures, I have only had one engine failure in my life, and in
that case a ring land broke off a piston on a new 428 Cobrajet. This
failure
was due to a metallurgical fault in the piston, and not related to
lubrication
according to the analysis Ford performed on the part, nor could it have been
predicted or prevented by your oil analysis.

The choice is yours, of course, but IMO there is no substitute for regular
and
competent maintenance of one's automobile.

Are you saying that aircraft turbines are serviced based on oil analysis?
