Car is a 2006 Saab 9-3 SportCombi Aero that has the 2.8L V6 Turbo and 6 speed auto. Factory hp is 250 hp and 258 lb. torque however I "tuned" it and is now 295 hp and 340 lb. torque--lots of power.
Car was bought new in April 2007. First oil change was done in May 2007 with about 3700 miles on the oil but I didn't do an analysis.
10,140 miles on this change, 13,700 total miles.
5 months of the oil. Total miles 55,200. Mostly highway.

Blackstone's comments on 4-8-09:
"DAVID: You ran this oil almost twice as long as what our universal averages are based on. But your engine
wear looks great. All of the wear metals we found read at or below those averages, which are based on
6,300 miles of oil use. We don't know what your secret is but you may want to patent it! The TBN was 4.7
showing lots of active additive left. Sodium may show a little coolant in the system, but we're not entirely
sure about that because with coolant we usually see potassium too. We'll know more when we see your next sample. Wear looks really good."

"The high wear metals and silicon are not unusual finds in the oil from your new Saab. In fact, we would have been surprised if we didn't find them. The wear is high due to break-in of new parts, while silicon is from sealers and sand-casted parts. Universal averages show typical wear metals for oil from this engine after 5800 miles of use. We expect your engine will look that good after future oil changes. The TBN was 5.2, lots of active additive. 1.0 is too low. Try an ~5000-mile oil change to get rid of excess metals in the oil and check before trying to extend oil use."
These comments are pretty useless and generic it seems. Did they realize this is the second oil change? And what are they talking about universal averages of 5800 miles? Where do they come up with these figures? And extended oil use, factory interval is 10,000 miles.
And is it normal for all these wear metals to be so high after the second oil change? Extended break-in period I guess...
So what do you all think?
