Can you mix hydraulic oil and diesel?

With care. The mechanics are interesting. I recently flushed out

an old 25 litre drum of hydraulic oil using unleaded petrol. I put

in a pint, flushed with the cap on tight, and the pressure rise was

massive. The cap blew right off as I released it. Same is true, to

a lesser extent as you mix with diesel.
