There is a gap between the wall of the container<br>& the chamber which I intend to fill with oil. There will be about an<br>inch of air at the top of the chamber & I'm using a scuba tank to<br>pressurise the unit up to 3000psi.<br>Will car engine oil do to fill the gap between my plastic container &<br>the chamber wall, or do I need to go with a hydraulic fluid.<br>Am using the plastic container to keep water from rusting my test<br>chamber.
