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.
you can not mix hydraulic oil in engine oil because if you do a fire will occure and then you will blow up in a million pieces.
A small amount of hydraulic oil mixed with a full tank of diesel fuel, nothing.
Yes you can mix oil and diesel for burning brush and stuff just don't put it in any engines!
apparently cooking oil with diesel
Depends on what the hydraulic oil is going to be used for, if you are going to use the hydraulic fluid in a really pressurized system, i would definitely drain it and discard it, that diesel fuel will dilute and break down the properties of the oil where it could be dangerous to use
yes very
I am not sure what you are asking but putting oil for diesel engines in a gasoline engine with some oil in it would not be good, or vise versa
not much. it would change the viscosity of the oil. the diesel oil is much thicker than regular engine oil.
Yes, you can also mix it with conventional oil creating a blend.
Blown head gasket
If it is the Toyosha diesel model, use a trans/hydraulic fluid.
Diesel has essentially zero solubility in water. That is the origin of the saying, "oil and water don't mix."
