Hi Guys,
Can anybody please tell me what is the correct hydraulic oil for my W123 230TE. I am able to buy Castrol Hydraulic Fluid Hyspin AWS. Which it describes as a high quality solvent refined mineral oil based hydraulic fluid, treated to inhibit oxidation/corrosion. Which sounds just the job, but is it correct for this system.I have checked past posts and have only been able to find that it should be" mineral based".

Any help would be much apreciated
David
