Does it matter which type of ATF is used?  Type A or Type F?

A friend, who is an SEL member, sent the info below.  Quite interesting.
Looks like I might buy a can of acetone and ATF.

Machinist's Workshop magazine actually tested penetrants for break out
torque on rusted nuts.  Significant results!  They are below, as
forwarded by an ex-student and professional machinist, Bud Baker.
*Don't forget the April 2007 "Machinist's Workshop" magazine comparison
test.*
**
*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 ............ 106 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. Our local machinist group mixed up a batch and we 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. *

*Your experience may vary, etc., etc.*
