IIRC, the '93 had Saab Blue G48 as factory fill. The Mercedes or Zerex G05 coolant (labeled for Daimler Chrysler/Ford) is similar and is what I would suggest. These 2 coolants give better protection especially in view of the engine construction (Fe/Al). If you want to use the Saab coolant, go ahead. If you use the G05, it'll similar protection and is easier/cheaper to find. Green stuff is similar (basically any standard coolant) in makeup, but is not as well buffered and should be changed more often. DexCool should be avoided like the plague in any car regardless of factory fill.
