[AT] Penetrating Oil Test

[Will Powell]

Gene, 

Great information. 

I've always used liquid wrench as my go to penetrating oil. 

PB-Blaster -Don't like the way it smells. 
Kana Kroil-Never Tried it 
WD-40-Use it all the time in my shop, but go to the Liquid Wrench for items that are stuck. 

Will have to mix up a batch of the ATF-Acetone. 

Regards, 

Will

Machinist's Workshop magazine actually tested penetrants for break 
out torque on rusted nuts. Significant results! 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. A local machinist group mixed up a batch and 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.
