I believe this info has been shown here
previously but better twice than never!

Machinist's Workshop recently published some information
on various penetrating oils. The magazine reports they
tested penetrates for break out torque on rusted nuts.
Below listed, a subjective test was made of all the
popular penetrates, with the control being the torque
required to remove the nut from a "scientifically
rusted" environment.
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 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.
NOTE: ATF = Automatic Transmission Fluid

The supposed mechanism here is that the lighter component (acetone or lacquer thinner) penetrates first and fast and as it evaporates off and out it sucks in the ATF. Also there is the thought that the mix is lighter than ATF alone and thus flows better. Why ATF instead of a light oil? I don't know. Perhaps some of the additives to ATF (detergents, friction modifiers and whatever else is in it) make it a better choice. Perhaps someone who actually has some facts (MattC or EmeryS) can chime in here.
Whichever you use remember that the acetone or lacquer thinner is more than happy to mess up what ever it comes in contact with that can be affected by that solvent.

The re-loadable spray cans have not been available for some time from Harbor Fright.
Gene - I can't read the picture well enough to find the answer. What are you using for the connectors?

I have been mixing up my own witch's brew for my bicycle chain lube for years - 50% acetone and 50% synthetic motor oil. I found that it penetrated and stayed in place a LOT better than any commercial lube I'd ever used. I never thought about using it in place of penetrating oil, but I'll have to try that... I could have used that just a couple days ago struggling with a REALLY stuck bolt on my son's Subaru (ended up using PB Blaster, lots of heat, and turned the wrench with a floor jack...).
