I'm a little skeptical of their test results too. From what I've seen working on my IH, PB Blaster soaks in better than Liquid Wrench. This was on 2 1" nuts that I had to remove to get the hitch off the rear to replace a broken sway arm. As for the torque used, it was me dangling in the air at the end of a 3/4" drive breaker bar with a 5' steel pipe over the last foot of the handle. I'm only 150 lbs. so sometimes I have to improvise.
I'll keep using both, just because I have Liquid Wrench in 1 qt cans, and the PB Blaster is in spray cans.
