New Penetrating oil
 
This was emailed to me and I haven't checked the accuracy but I thought I would share. This is old so my apologies if this has been posted before.

"Machinist's Workshop" (March/April or May/June, 2007) published information on various penetrating
oils. The magazine reports they tested these products for "break out
"torque" on rusted nuts and bolts. A subjective test was made of popular
penetrating oils, with the unit of merit being the torque required to
remove the nut from a "scientifically rusted" bolt.

Average torque load to loosen nut:
No Oil used ........................516 foot pounds
WD-40 ..................... ........238 foot pounds
PB Blaster .........................214 foot pounds
Liquid Wrench ......................127 foot pounds
Kano Kroil .........................106 foot pounds
ATF/Acetone mix...................... 53 foot 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. ATF = Any type of Automatic Transmission Fluid

This version of the story was in one of the Military Vehicle Club newsletters.

Welcome to RRR, this was posted up a few months ago. I use the 50/50 blend in my shop along with some PB.
