You say that the manual lists 20W50 motor oil as a substitute for the Hydro oil. I'm a little leery of using motor oil for hydraulic systems. I used HyTran in my old 1450 and the newer synthetic Drive System Plus in my 3235. I've read other posts here about using motor oil but to me it always seemed to have a much different vicosity than hydraulic oil. If all else fails you might want to consider flushing out the motor oil and replacing it with the correct hydraulic oil.
Just my two cents.
