Pentrating oil?

[BenzBoy]

I am advised that an excellent penetrating oil can be made from one part ATF to one part acetone. Has anyone tried this recipe?

Hi BenzBoy, I haven't tried it, nor have I ever known about this particular mixture, 'concoction'. It seems so much easier to spend five or six bucks on the recognized anti rust-seize pressure packs and just squeeze the button. Regards Styria

I have seen the test results for the various penetrating oils, and the acetone / ATF mix is half of penetrene and about 1/3 of WD40.

John - what was the source for that test?
All I am able to find is the following which would seem to indicate that the ATF/acetone mix is the most effective.

and the old stand by - overn cleaner..

Well, that seems to be overwhelming evidence in favour of ATF/Acetone -what more can I say ? Regards Styria

Very convincing - just watch the paint.

How does neat acetone affect sealing rubbers? Is there a solvent risk?

Acetone should not affect pure rubber but it will attack any synthetic - paint/composite gaskets etc and should be used with caution because of that.

Hi BenzBoy, have you used it yourself, or have you just read about it somewhere ? I note your summary and findings further on in the thread. Considering the possible side effects, is it worth taking the gamble, for one, and under what circumstances should one really need a mixture that could potentially be as lethal or damaging as this one ? In my experience, once the usual penetrating solutions available fail to perform the task, the item to be treated and removed is beyond saving in any case. Regards Styria

Dear Styria - Yes I have used it to help loosen bolts in a chassis rail. Such bolts had probably not been cracked in over seventy years. Far from being beyond use, the bolts were in excellent order once cleaned and greased.

Well, the proof of the pudding is in the eating, and I certainly accept that. I sort of can't talk about chassis rails and bolts therein, but I can compare the method of securing, say, front guards between Mercedes and Rover Cars. Mercedes uses 10mm hex headed self tappers that are screwed into caged nuts, whereas Rover uses 7/16in. bolts that screw into nuts that are welded to the inner guard, and I must say that the Mercedes method has created problems as far as removal of bolts were concerned, despite the liberal application of penetrating oil - the one marketed by CRC.
