[ARC5] Turbine Oil

[Fuqua, Bill L]

    Speaking of WD-40. There is a common email that circulates from time to time about 
a the NASA engineer that was said to invent it. The email goes on to say that it is made of 
fish oil and has many uses including cooking.
     I have not seen this one for sometime but the cooking oil bit is in some versions and not others.

  Most of the bad rap that silicone oil gets comes from body shops since it is not compatible with
organic solvents one spot on a car body causes fish eye.
  Silicone based grease are used often in bearings that are exposed to
wide temerature extremes, I bought a tube of it at a local bearing supplier for my rotator.Even IBM used  silicone oil, well kept secret for many years,
to prevent fretting oxidation in IC sockets. It was quite some time later that the first articles about fretting oxidation
were released. They would put a tiny amount on each IC pin before inserting it into the socket.
  My associate engineer years ago used to refer to it a crunch. The chip would work its way out of the socket
a bit and when you pressed down on it made a crunching noise. After the crunch the board would function correctly
again.

Diff pump oil's claim to fame is a very, very low vapor pressure. Nothing
more.

And silicone oils are damn near impossible to clean off.
