See if I can pull some details out.
Machinist's Workshop magazine tested penetrants for break out torque on rusted nuts with 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 (obviously a BIG nut!).
Penetrating oil ...... Average torque
None ....................... 516 ft lbs
WD-40 ................... 238 ft lbs
PB Blaster .............. 214 ft lbs
Liquid Wrench ..... 127 ft lbs
Kano Kroil ............. 106 ft lbs
ATF-Acetone mix....53 ft lbs
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. Our local machinistgroup mixed up a batch and we all now use it with equally good results.

Is the ATF similar to hydrolic oil ? I never put my hands in it.
I've noticed on a rusty bolt it will start bubbling at the hole, making it look like it's penetrating. I had some ZEP stuff used to do that.
I tried ATF drain oil from changing my sisters Honda Accord for bar oil. Not much of a lubricant in that application. I was surprised.
I think ATF varies a lot. Some of the new stuff smells like cat whiz.
Just as general info DHMO is a super solvent used in industry .Technical grade did have amounts of mercury in it .Medical grade not recommended for humans was used on the joints of race horses and had no mercury .
Veterinarins carried it .If you use it be very careful because it's skin absorptive
Good thread. Very applicable.
Tight thread even, might need penetrating fluid to loosen it up
