Riff, The W50 of the multiviscosity is not needed. I had tried it in my 83 900T and went back to 10W40. Using 5W50 or 20W50 can create problems you don't want or need, especially if yours is a turbo model. Aside from the fact that no Saab owner's manual I have seen calls for anything beyond 10W30 or 10W40 in the crankcase...So unless you have more collective experience than all of their engineers, I wish you luck.
