blackmercedes - I do not undertand do you change it yourself? and what is SDS and how it tells you the level? I also do have a 722.6 but I am cluless. I am reaching 100K Mi and was wondering when to change the fluid.
I know it is fill for life but what is a life of a car? I am under the impression it may be 120K mi.
