I recommend that you continue to us the MB hydraulic fluid, part # 000989910310. I've had customers use different fluids that aren't compatible and turns the fluid into almost a grease.

This.

The OEM stuff is expensive. Use a clean turkey baster to get the old stuff out or something else similar.
