Penetrating oils
Has anyone seen this information and what do you think?
(Beginning of Quote) Penetrating Oils Machinist's Workshop magazine recently published some information on various penetrating oils that I found very interesting. Some of you might appreciate this. The magazine reports they tested penetrates for break out torque on rusted nuts. They are below, as forwarded by an ex-student and professional machinist. They arranged a subjective test of all the popular penetrates with the control being the torque required to remove the nut from a "scientifically rusted" environment. *Penetrating oils ........... Average torque load to loosen* No Oil used ................... 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 is a "home brew" mix of 50 - 50 automatic transmission fluid and acetone. Note this "home brew" released bolts better than any commercial product in this one particular test. Our local machinist group mixed up a batch and we all now use it with equally good results. Note also that "Liquid Wrench" is almost as good as "Kroil" for about 20% of the price. Steve from Godwin-Singer says that ATF-Acetone mix is best. (End of Quote)

Re: Penetrating oils
Good stuff, thanks Mike. I'm assuming you only use Type "F" on Ford products??

Re: Penetrating oils
Probably a bad assumption Dennis. My Merc has a very large pool of trans. fluid beneath it right now, from using the wrong ATF this last summer . The NAPA guy wasnt right, and I forgot what the correct fluid should be.

Re: Penetrating oils
This old info makes the rounds every couple of months. A lot of people have read this post, but has anyone proved that it really works? I tried this mix on pistons seized in the cylinder bores, didn't do anything for me.

Re: Penetrating oils
I have used the 50/50 blend. I always have a large asortment of ATF on my shelf, but since I am usually out of acetone, I have subsituted Lacquer thinner for the acetone and I still have had the same good results.

Re: Penetrating oils
Dennis, dont remember! Dimentia? After it goes and comes from the transmission shop I'll permanently label the correct fluid on the car, whatever it is. The trans is 2 speed.
As to the penetrating oil, it sounds like something I will try. On Several engines I've had with badly seized piston rings, nothing worked but a hammer and stick.

Re: Penetrating oils
Have used it for years, and works excellent. Just need to shake it before usingcuz the ATF settles. I put it in an old WD40 spray bottle. The acetone will attack some of the cheaper pumps in the spray bottle.

Re: Penetrating oils
I'm a believer of pb blaster, If I'm taking apart an old ford I try to pre spray the screws, and hardware. It has saved me many times when I couldn't get something to break free. I bought the gallon jug with the pump spray bottle, Mark

Re: Penetrating oils
I have used most of the mentioned types, and was truly astoished when I used an acetone/atf mix (removing stuck brake drums from the shoes). I used about 20 percent tone and the rest was oil atf.l It doesnt matter if its Ftype or any other given type!
