Got my UOA from Blackstone yesterday. The relevant info: '03 9-5 Aero, 14,414 miles when sample taken, 3,776 miles on this oil, from March 4th to May 8th. This was the oil and filter from the "free" 10k service at the dealer. I was told it was a full synthetic, the reciept said 5W30.

"Aside from a little gas in the oil, this analysis result looks normal. You can pick up this much gas from city driving and idling. It was enough to affect the viscosity, but we doubt your engine wear could get much better than this, after a 3,776 mile oil use run. Our average sample from this type of engine has 4,370 miles, so you could go a bit longer if you wanted. Your bearing wear metals are doing very well, so we think this oil type is working well. Upper cylinder wear was average. No moisture or signs of any engine coolant found. Nice wearing Saab engine!"

Properties
Were Should
Viscosity 55.6 56-63
Flashpoint 340 365
Fuel % 1.3 Antifreeze 0 0
Water % 0 Insolubles % 0.3 Did not get a TBN
So, what do you guys think? Looks like whatever the dealer put in did not have much in the way of Moly, that lead to any conclusions about it's possible identity?
We put those 3,776 miles at a much faster rate than we put the first 10k. Ran into some paperwork problems with the wife's Civic that kept it off the road for a couple of months, so the Saab saw extra duty. My wife put many of those miles on with her 20 mile commute, almost daily 1 mile trips to the gym and other short errands. Now that the Civic is back, the 9-5 won't be doing those short trips, so hopefully that gas % will get dropped.
I changed it to Mobil 1 5W-40 and a PureOne filter, which will stay in there for ~5,600 miles to the 20k dealer service.
