Subject: = Penetrating=20 Oil

"Machinist's = Workshop" recently=20 published information on various penetrating oils. The magazine reports = they=20 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=20 measurement being the torque required to remove the nut from a = "scientifically=20 rusted" bolt.

Average torque load = to loosen=20 nut:

No Oil used=20 .........................516 foot pounds

WD-40=20 ...............................238 foot pounds

PB Blaster=20 ..........................214 foot pounds

Liquid Wrench=20 .......................127 foot pounds

Kano Kroil=20 ..........................106 foot pounds

*ATF/Acetone mix=20 .....................53 foot pounds*

*The ATF/Acetone = mix is a "home=20 brew" mix of 50/50 automatic transmission fluid and=20 acetone.

Note this "home = brew" released=20 bolts better than any commercial product in this one particular = test. Our=20 local machinist group mixed up a batch, and we all now use it with = equally good=20 results. Note also that Liquid Wrench is almost as good as Kroil = for about=20 20% of the price.

ATF/Acetone mix is = best, but=20 you can also use ATF and lacquer thinner in a 50/50 = mix.

ATF =3D Automatic = Transmission=20 Fluid
