The level in the reservoir next to the radiator and washer fluid in my SL600 is showing low - what type of oil is required? Am I right to assume it's for the suspension system... don't have WSM yet and there is no mention in the owners manual other than MB hydraulic fluid.
Also, what type of oil is used for the top? That too is showing low, it is measured with top up or down?
Last, I have LHM (green stuff that I use in the Citroen hydraulic system) will that work vs the MB product?
