I don't know if this has already been posted this but this is good info.
Be good! Roland.

Penetrating Oils Compared

Machinist's Workshop magazine actually tested penetrants for break out torque on rusted nuts. Significant results!

*They arranged a subjective test of all the popular penetrants with the control being the torque required to remove the nut from a "scientifically rusted" environment.*

*Penetrating oil ..... Average load*

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 ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic transmission fluid and acetone*
*Note the "home brew" was better than any commercial product in this one particular test. A local machinist group mixed up a batch and all now use it with equally good results. Note also that "Liquid Wrench" is about as good as "Kroil" for about 20% of the price.*

interesting results, however I don't know how you could 'scientifically' rust something. sounds like the study control has quite a bit of variables in it.

but all in all some interesting info, do you have a link to the study at all?

But This has been ****** around the internet so many times I doubt anyone actually knows its true origins, I've seen this on airboat sites, GMFS, and even a bowfishing site a time or two.

I use Kroil religiously and the only penetrating oil I use anymore, if I know I have to break a part down the next day I spray my **** down, then the next day an hour before tear down I spray it again. The oil will climb itself and creeps so much better than Blaster or WD40. The problem with the acetone/atf mix lies in storing it, most of us would put it in a plastic reusable squirt bottle, but with in a few hours the acetone eats the plastic bottle up and leaks out.

I got a few quarts of used atf and some new, I'm gonna make me some home brew with acetone, just have to go buy some.

I know my dad always said atf and kerosene makes for a good degreaser.

i should mix some of that up. i got a lot of atf laying around and my dad works at a chemical plant so he can get the acetone by the gallon for free

I love Liquid Wrench products.

I read on the Gearz website that Tabasco sauce works good. Sure enough, it works awesome. I used it to remove my header bolts when I rebuilt my engine and it worked like a charm. I think it has to do with the acid in the sauce.

Hmm looks like I'll be picking up a bottle of Liquid Wrench instead of PB Blaster tomorrow...

I use ZEP45 its great stuff!! I put some on my fuel filter the day before I removed it and about an hour before I removed it and it came off pretty easy! I never thought in a million years it would break loose on a 95 sierra from Minnesota with 170,000 miles on it!!
