Find this of great interest and will test it on a well rusted 300K ram engine in the back yard.

Just some interesting information to us that still mess around with a wrench and pliers at times...John


Penetrating Oils 


Machinist's Workshop magazine recently published some information on various penetrating oils that I found very interesting. Some of you might appreciate this. The magazine reports they tested penetrates for break out torque on rusted nuts. 


They are below, as forwarded by an ex-student and professional machinist. They arranged a subjective test of all the popular penetrates with the control being the torque required to remove the nut from a "scientifically rusted" environment. 


*Penetrating oils ........... 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 about 20% of the price. 


Steve from Godwin-Singer says that ATF-Acetone mix is best, but you can also use ATF and lacquer thinner in a 50-50 mix. 
*ATF=Automatic Transmission Fluid
