The April/May edition of Machinist's Workshop did a test of penetrating oils to see how much force was required to break test parts apart.
Oil Used/ force needed /price per fluid ounce

nothing 516 lbs
WD-40 238 lbs $0.25
PB Blaster 214 lbs $0.35
Liquid Wrench 127 lbs $0.21
Kano Kroil 106 lbs $0.75
ATF/Acetone mix 53 lbs $0.10 (1:1 mix)
confirmed my fears of WD40 being a featherweight; kind of disappointed in PB Blaster; renewed opinion of Liquid Wrench.
