The few times I've tried it, it's not helped ...They tend to be low viscosity. But other than that, I am not sure.
I have never had penetrating oil work for me, not in any capacity. I think it's a "feel good" item to use.
I've heard of Mouse Milk ... never tried it, though.I have this one called Mouse Milk that IMO penetrates better than anything else I've tried. Stuff smells like lacquer thinner.
What allows or makes a penetrating oil penetrate? What additives or characteristics does it have that sets it apart from other oils, including MMO?
I don't remember where I was introduced to it but years ago I got a bottle of it. I had to do the 02 sensors in my truck. I got under the truck and applied Mouse Milk to the warm 02 sensors with a Q Tip. Watched it run right in. About thirty minutes later, I broke both sensors loose with a wrench and spun them both out with my fingers.I've heard of Mouse Milk ... never tried it, though.
Thanks for that informative post.The real workhorse ingredient in any penetrating liquid such as the rust busters is a special surfactant or "surface active agent" which reduces the surface tension of the liquid so it can spread.
Once the spreading takes place, any porous material like rust can wick it up and the other chemicals can attack the rust or scale. Then a rust reduction or loosening chemistry goes to work.
The penetrant mix should also provide some friction reduction.
Many times it takes penetrating oil + an impact wrench + heat to 'convince' nuts or bolts to free up.
Which version; the Blue or Green?I don't remember where I was introduced to it but years ago I got a bottle of it. I had to do the 02 sensors in my truck.

I'm currently using it again to try and free up a stuck seatpost in a friend's bicycle frame.
Thats what i use. I mix it up as needed, since acetone evaporates fast. 50/50 mix.My home made mix of ATF/Acetone seems to work about as good as any I have bought.
I remove tons of GM/Ford 10x1.5mm exhaust nuts, Without a penetrant you run a higher risk of them galling on the stud.They tend to be low viscosity. But other than that, I am not sure.
