There was a article a couple years back, the link has since been disabled, so here is a copy/paste of the one section.
Article in the April/May 2007 issue of Machinist's Workshop.
They corroded of nuts/bolts so there were enough samples to try out the various penetrating oils on.
The nuts/bolts were tested by soaking them in the penetrating oils for 8 hours.
The load needed to break the nuts free was tested using a Baldwin compressometer.
The results (lower is better):
> 50/50 mix of PSF & acetone - 53 Lbs
> Kroil - 106 Lbs
> Liquid Wrench - 127 Lbs
> PB Blaster - 214 Lbs
> WD-40 - 238 Lbs
> None - 516 Lbs
