Please forgive the previous no message, finger slipped. I need power steering fluid for my 94 530i. Resovoir says "CHF 11S only". Common p/s fluids locally have no reference to this on labels. I assume this is some sort of hydraulic fluid that is required. Does anyone have a definitive answer as to what can be used that can be easily found? I'm in rural eastern NC with somewhat limited resources locally so far as fancy p/s fluid & other ferrin car stuff is concerned. Thanks-Bob Thomas
