Kroil is one of the best on the market in my humble opinion. Blaster is also fairly good. Price wise, Blaster is much cheaper than Kroil.
I tried the acetone/tranny fluid mix. It seemed to work well, but I had trouble keeping the two mixed properly. Not sure what the issue was, but it separated on me, and the acetone evaporated off.
The idea of a good penetrating oil is to have a very low surface tension. This allows it to literally penetrate the microscopic pores in the rust crystals, and "break them down" somewhat. Lubrication is also an important factor. If you look at Kroil and Blaster, they have the correct characteristics mentioned: low surface tention and lubricity. Solvents are great for penetrating microscopic pores, but they have little to no lubricity. Diesel is a good low viscosity lubricant, but has a much higher surface tension than Kroil or Blaster.
An independent study showed that the Acetone/tranny mix was one of the best penetrants. They tested penetrants for break-out torque on rusted nuts, with interesting results. They arranged a subjective test of popular penetrants, with the control being the torque required to remove the nut from an equivalent "scientifically rusted" environment:
Penetrating oil ........... Average load to break free
None ..............................516 pounds
WD-40 .......................... 238 pounds
PB Blaster .....................214 pounds
Liquid Wrench ............... 127 pounds
Kano Kroil ......................106 pounds
ATF-Acetone mix............ 53 pounds
The Acetone lowers the surface tension of the tranny fluid and "transports" it into the pores.....then evaporates.
