[AT] Penetrating Oil Test

[Robert L. Holtzer]

This "test" got a lot of circulation since 2007.  Has anyone  on this 
net seen the actual test procedure used?  Are the results averaged 
from several individual tests or ...?  Apparently some effort was 
made to standardize the "rusting" -- does anyone know how?  How was 
the torque measured?  Etc.?  What type of ATF was tested?

I don't have access to the magazine but would be interested if 
someone has actually read the article and test procedure.
