Gents, I have a new (to me) 95 E300D and have changeg the tranny/engine fluids. Looking in the provided manual it calls for MBZ power steering fluid/brake fluid. Is it nec to use the MBz stuff. Is the p steer fluid ( reddish brown) compatable with reg PS fluid? Any dot4 brake fluid? It's a 2 hour drive to the nearest dealer so using something local would be nice.
