Not doubting the effectiveness of penetrating oils.............but please explain how the 516 lbs vs the 238,214 etc.......were concluded.
If they broke it loose with 516 lbs of force, why/how did they determine it took on X amount with the oil after it had been broke loose?
Rhetorical, no real need to answer. I live about 300 miles north of Houston, or I'd volunteer to help rescue your equipment. BTW, I live in Texas and I have a basement. A water line busted once and I had water up to my table saw table. I lost nothing to that flood, not even an electric motor. Very lucky, but judicious drying and a couple of applications of oil will do wonders.
