Thought I would post this info here because I know I'm always looking for a better penetrating oil for those stubborn screws.
I haven't tried it yet but will be next time I work on my jeep or changing a scope base or ......
Some interesting information for the Mechanically Inclined.
For all of you that are mechanically inclined.....
Penetrating Oils Compared
Machinist's Workshop magazine actually tested penetrants for break out torque on rusted nuts. Significant results! They arranged a subjective test of all the popular penetrants with the control being the torque required to remove the nut from a "scientifically rusted" environment.
Penetrating oil .......... Average load
None ..................... 516 pounds
WD-40 .................... 238 pounds
PB Blaster ............... 214 pounds
Liquid Wrench ............ 127 pounds
Kano Kroil ............... 103 pounds
ATF-Acetone mix............ 53 pounds
The ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic transmission fluid and acetone.
Note the "home brew" was better than any commercial product in this one particular test. A local machinist group mixed up a batch and all now use it with equally good results. Note also that "Liquid Wrench" is about as good as "Kroil" for about 20% of the price.
