Convertible top sluggish. Suggestions?

[PhilG]

996 (1999) top operation is sluggish. You tube videos say to change the hydraulic fluid and gives instruction, but does say what fluid to use. Does anyone have recommendations on which fluid to use? Thanks !

I was able to find two options for it, Genuine Porsche Convertible top hydraulic fluid and Febi Porsche Convertible top hydraulic fluid
