This bit of info was passed on by Dual Sport Alchemy’s favorite back yard engineer, Frank Morton. Apparently it’s been around for a few years but it’s new to me and confirms my long time suspicion that WD-40 works best as a cleaner. So for everyone with a DIY mentality who prefers to turn their own wrenches, here’s some great test results for Penetrating Oil.
Penetrating Oil -Test Results 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.
