The article reported that they tested penetrates for break out torque on rusted nuts. This was a subjective test of all of the popular penetrates with the control being the torque required to remove the nut from a "scientifically rusted" environment.
*Penetrating Oils - - - - - - - Average torque load to loosen
No Oil Used - - - - - - 516 pounds
WD-40 - - - - - - - 238 pounds
PB Blaster - - - - - - - - 214 pounds
Liquid Wrench - - - - - - - 127 pounds
Kano Kroil - - - - - - - - 106 pounds
ATF*-Acetone mix - - - - - - - - 53 pounds
The ATF-Acetone mix is a home blend of 50% each, lacquer thinner can be used in place of the acetone.
I recently used this on the Shock bolts in the front axel and was able to remove the bolts with out drilling them. I did allow two days for the mix to seep into the rusted parts.
