Just wondering if any of the mixers on the board care to comment on what is the difference between a "penetrating" oil, and any other oil?
What makes a good penetrating oil??

A penetrating oil usually has two main agents: a surfactant that reduces the surface tension of an oil so that it flows into tight spaces and a polar component so that it clings to metal surfaces.

A anti-rust/anti-corrosion compound is also added to bust rust.

Is there anything better than PB Blaster or Kroil?
"BG In Force" works better than PB Blaster. However, it costs $15-$20 per can.
I used Free All the last time I had to get hard to remove bolts off and it seemed to work better than PB Blaster.

Used to read a lot about Kroil when Shooters online still existed.
Can't get it downunder.
One of my turbines is coming apart at present, and pressing pins out of blades and rotors is WAY easier than we've seen before. Asked the maintenance supervisor today what they were using, and it turns out to be Kroil.
They import it, just over $250 Aus per Gallon, but it seems to giterdun.

This is from an April post on penetrating oil. Note that acetone and ATF were the best.
"The April/May 2007 edition of Machinist's Workshop did a test of penetrating oils where they measured the force required to loosen rusty test devices. Buy the issue if you want to see how they did the test. The results reported were interesting. The lower the number of pounds the better. Mighty interesting results for simple acetone and tranny fluid!
Penetrating oil . Average load .. Price per fluid ounce
None ................. 516 pounds .
WD-40 .............. 238 pounds .. $0.25
PB Blaster ......... 214 pounds .. $0.35
Liquid Wrench ... 127 pounds .. $0.21
Kano Kroil ........ 106 pounds .. $0.75
ATF-Acetone mix.. 53 pounds .. $0.10
The ATF-Acetone mix was a 50/50 mix (1 to 1 ratio)."

LC20 and ATF also make a great combo.
I am kinda surprised. I have tried WR and PBB and I have always seen PBB worked better at loosening frozen/rusted parts. WR never worked for me. And PBB saved my doorlocks and steering shaft.
