V principe som nasiel 2 verzie ultimatneho (vykonom aj cenou!) penetracneho oleja:
*jeden zdroj vravi 50/50 aceton/ATF (ATF alebo aj PSF-power steering fluid, je to to iste)
*druhyu zdroj atakuje platbyschopnost nasej penazenky este vyaznejsie a vravi 10/90 aceton/rastlinny olej
strasne rad by som to oskusal na poloosiach starej MR2 ktore nesli povolit ani parom volov, no bohuzial to zu nieje mozne tak jednoducho lebo poloosi su uz dole z auta. ale akonahle najdem daky srob-buzerant, dostane kuru raciolomFebruary 2, 2008

Article: “Testing Penetrating oils”
This reports a test of penetrating oils where they measured
the force required to loosen rusty test devices. The
details reported here were validated by the original
article author. He also added some details on the methods.
You must buy the issue if you want to see how they did the
test. The back issue is available for purchase.
The table below extracts the results table The lower the
number of pounds the better. Interesting that a simple mix
of acetone and power steering fluid (PSF) works the best!
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
PSF-Acetone mix 53 pounds $0.10 (50/50 mix)
Note from original article author:
1) These are loads required to free the test piece after
8 hours of immersion in penetrating oil. This is
probably not representative of a quick squirt just
before a wrench is applied.
2) The original article states ATF was used in the DIY
mix. It was actually PSF. I corrected the table to
