That car takes ATF as its power steering oil - the mercedes and Febi oils are just that without the dye and a lot of anti foam stuff. The Febi oil is sold at NAPA too.

Motorcraft Mercon V is a very good power steering oil as it behaves very well in cold too - the only downside to it is that its very smelly.
