For a 1990 I really like synthetic motor oil like mobil1. In the winter, I would use 10w-30. in the summer 10w-40 or even 15w-50 if you have over 100k on the engine.
You have to use a special and expensive fluid for the power steering. The part number is 000 989 88 03. You will have to go to a good import part store for this, it is made by Bilstein. That is what the factory recommends.

Any NAPA, Autozone or Pepboys sells the fluid you need. It's not that expensive. AMSOIL is far more superior to mobil one.
