Various Penetrating Oils and Effectivness
Just found this regarding penetrating oils on another site.
rusted bolt penetrating oils > FYI
(I got this in an email recently. Might be useful).
Interesting article
"Machinist's Workshop" recently published information on various penetrating oils. The magazine reports they tested these products for "break out "torque" on rusted nuts and bolts. A subjective test was made of popular penetrating oils, with the unit of merit being the torque required to remove the nut from a "scientifically rusted" bolt.
Average torque load to loosen nut:
No Oil used .........................516 foot pounds
WD-40 ..................... .........238 foot pounds
PB Blaster ..........................214 foot pounds
Liquid Wrench .......................127 foot pounds
Kano Kroil ..........................106 foot pounds
ATF/Acetone mix..................... 53 foot pounds
The ATF/Acetone mix is a "home brew" mix of 50/50 automatic transmission fluid and acetone. Note this "home brew" released bolts better than any commercial product in this one particular test.Our local machinist group mixed up a batch, and we all now use it with equally good results. Note also that Liquid Wrench is almost as good as Kroil for 20% of the price. ATF/Acetone mix is best, but you can also use ATF and lacquer thinner in a 50/50 mix. ATF 3D Any type of Automatic Transmission Fluid

Had a friend that worked for the military maintenance. He brought me some stuff In a green can with just a number on it. Everyone called it skeeter pee. Had a very distinctive oder to it but worked extremely well. Thanks for posting this, very informative.
