Very interesting.... 




For All of you Mechanic's and Self doer’s out there. 
Penetrating Oil - interesting 
This was in one of the Military Vehicle Club newsletters 
Here is an interesting article submitted by Bob Muller for our members consideration 
Penetrating Oils 
Recently “Machinist Workshop Magazine” did a test on penetrating oils. Using nuts and 
bolts that they ‘scientifically rusted’ to a uniform degree by soaking in salt water, they then 
tested the break-out torque required to loosen the nuts. They treated the nuts with a variety 
of penetrants and measured the torque required to loosen them. 
This is what they came up with: 
Nothing: 516 lbs 
WD-40: 238 lbs; 
PB Blaster: 214 lbs; 
Liquid Wrench: 127 lbs, 
Kano Kroil: 106 lbs 
(ATF)/Acetone mix (50/50): 50 lbs. 
This last “shop brew” of 50% automatic transmission fluid and 50% acetone appears to beat 
out the commercially prepared products costing far more.
