My '92 w/167k has cold morning steering sickness. It has no leaks (at least not yet). I want to replace the P/S fluid and add some 'Lucus'. I'm going to use a turkey blaster to remove the old fluid (I don't want to disturb the p/s hoses). My ??? is should I replace it with fresh Dextron and drive it for a week or so and drain it again and then add the Lucus or just add the Lucus the first time... I want to get in as much fresh fluid as possable...
