Hi,

My 83 300D makes some groaning noises when steering when first started for the day. I checked the PS fluid and it is a little low. Whenb I went to the store, I noticed there are two distinct types, fluid for Honda/acura cars, and fluid for all other cars. The honda fluid must have something special in it that makes its use required. I guess it must be for seal compatability, or operating temperatures/pressures, or something like this.

My question is, it is more expensive, and seems to be a superior fluid. would there be any benefot to using Honda fluid on non honda cars, like in my MB, when PS fluid is specified? If used, will it ruin parts of the PS system in non-honda cars?

Any info is most appreciated.
Thanks
