Dexron III ATF or MB Power Steering fluids are the recommended PS fluids for your car For that era, MB PS fluid is basically ATF with improved cold flow properties. U.S. PS fluid is not recommended for ANY Mercedes, and Pentosin CHF 11S (synthetic) is recommended for SOME of the newer models. One possible problem with using non-recommended fluids is incompatibility with seal materials which COULD cause leaks. For my car, I use Mobil 1 synthetic ATF.
