"The April/May 2007 edition of Machinist's Workshop did a test of
penetrating oils where they measured the force required to loosen rusty test
devices. Buy the issue if you want to see how they did the test. The
results reported were interesting. The lower the number of pounds the better
. Mighty interesting results for simple acetone and tranny fluid!
Penetrating oil . Average load .. Price per fluid ounce
None ................. 516 pounds .
