No. They separate. Gum up.hydraulic fluid heavier.

It's impossible to say unless you know exactly what chemicals you're mixing. But why would you do this anyway? Power steering fluid costs almost nothing, so why risk mixing chemicals and possibly damaging your system?

Some system will accept it, some won't. Use the recommended fluid for your car. Simple.
