B112 Hydraulic Fluid

[lucius 0]

I need to add some hydraulic fluid to my B112. The fluid that is in there is red in color and looks like transmission fluid. The manual says to use 30 weight oil, but I don't want to mix what is in there with another fluid. Is it common to use transmission fluid in these systems? Thanks, Milt Lucius

No Instructions call for 10W-30 only.
