Chris,
From what I know, it's Mobil-made 0W-30. All the '03 Saabs are coming with a "Use Mobil 1" advertisement in the engine compartment. The only thing I haven't heard yet is whether it's US made or Euro made. It's API-SL, ACEA A1/B1-A5/B5 rated, & includes the new GM/Opel LL-A-025 long-life spec. I haven't been able to get a "real" price from any of the 3 dealers in my area; prices ranged from $5.25-$10.78 per liter bottle, & $21-$28 for a 4-liter jug, but they all admitted their quotes were suspect.
Two interesting side-notes here:
1) Reports from folks who work in the assembly plants in Sweden & Finland say that ALL the turbocharged cars get M1 0W-40 as factory fill, regardless of their destination or manual's recommendations. Saab even has an OE full-syn 0W-40 oil, but it's not distributed in the US. All the local dealers can pull it up on their screens via "the Swedish P/N," but none of them can bring it in.
2) I have 5 liters of 1 yr old Saab OE 5W-30 semi-syn, & it doesn't have any US markings or P/Ns on it. The remarkable thing is this: the same oil with a US P/N is API-SL, ACEA A1/B1 rated, but this "un-US" oil is SJ, A3/B3 rated. I've heard speculation that all the OE 5W-30 semi-syn is also Mobil-made, & the bottle looks frighteningly similar, but I have no real proof. I'm guessing it's Euro-Mobil, but EuroM1 web-specs don't list any ACEA ratings for anything but their 0W-40.
