Gehl ctl80 hydraulic fluid

[jkimmerling]

Hello, I am new to the skid steer world. I have a mustang mtl25/Gehl ctl80, and it is a bit low on hydraulic fluid. The manual says it uses 10w/30 API-CD oil. Apparently that oil is obsolete, so I need to know what the new version is called. Any help is appreciated

People get hydrostatic fluid from tractor supply companies. I personally use engine oil 20W50 or 10W30, whatever is on sale.
