We've heard this before about brake fluid.
Anybody know why brake fluid would be manufacturer used over hydraulic oil. Brake fluid seems just plain dumb for all kinds of reasons, not the least of which is that it is hygroscopic for heaven's sake - duh... But we are not engineers. What do you engineers say?
Since it is available, today we guess that one should use top of the line true synthetic hydraulic oil but which brand and exactly which Spec.? On expensive to fix cars, people today are using more and more Red Line, Royal Purple, Amsoil and the like.
We are interested in reading what knowledgeable others have to say.
Sooo what should we do and why?
