Phosphate corrosion. I'm pretty sure Saab's anti-freeze is made by BASF
(who make lots of OEM anti-freeze). Their trade name is "Zerex". The Zerex
Extreme product is probably the very same stuff as the Saab dealer sells
you. There are concerns about mixing these sorts of coolants, so you have
to completely flush the system. The Zerex product has been approved by BMW,
Mercedes-Benz, Audi, VW, and others. It's probably worth checking to see
if Saab is on the list (BASF numbers: BASF Customer Service: 1-800-445-4134

Propylene glycol based (Propylene glycol is a food additive of some
sort...). Performs very much like traditional ethylene glycol based
anti-freezes. If it's made with correct bunch of additives (corrosion
inhibitors, things like that) it should work just fine. Oh, and just
because it's made with propylene glycol doesn't mean you should dump it down
the drain! There are nasty things in used antifreeze, and all anti-freeze
should be properly disposed of -- recycled.
