Hey Scott,
The Saab 0W-30 Full Syn is ACEA A5, just like the Mobil 1 0W-30. The 5W-30 "Semi Synthetic" used to be A3, but they seem to have changed the formula a bit & now it's rated A1 (it happened around the same time they changed the name to "Synthetic Blend").
An interesting side note:
I've never run OE oil in my '90 Saab 900 (non-turbo) for the nearly five yrs I've owned it. With all the oils (either dino or syn), I've always had a slight tick on cold-start-up (general opinion on SaabNet is valve noise), which would go away after a few seconds. Filters have always been Saab OE, Mann, UK-ACD, or PureOnes. For the past 10 mos I've been running M1 15W-50 & have the same noise; no big deal.
I'm leaking a small amount of oil, so when I needed a 4oz top-up I used the Saab A3-rated 5W-30 I've got. My cold-start-up tick immediately went away, & has stayed away for over a month! I can't explain it, except that maybe the extra diesel-style additives are part of the "OE intent" of the oil spec? All I know is, I'm seriously considering running Delvac 1300 Super in this car on my next oil change!
