Long time lurker, first time poster. I purchased this Aero at 108,XXX miles and immediately performed coolant flush, oil change (to RP 0W-40 w/ Napa Gold Filter), Spark Plugs, etc. All standard serviceable items. I found the usual discrepancies; incorrect coils, plugs, filter etc. I ran the oil for 5,756 miles. I don't like running over 6k, and since I drive a lot, I don't personally have a time limitation on oils. My bike won't go past 4, maybe 5 months if the weather is bad and I don't ride. I chose RP because I have had a horrendous experience with Mobile in another Saab of mine (1985 900 Turbo) and will never repeat that mistake. I fell for the Amsoil sales pitch and put in 0W-30 Signature after this Royal Purple, which I just can't justify the price for with so many other options meeting and exceeding GM-LL-A-25 / Dexos2. I'll ask about that later as well. Not quite sold on Pennzoil Platinum, but still looking. No oil additives in this one, only fuel. Seafoam and Chevron Techron cleaning. I have used ASL CamGuard in aircraft for years and have seen astonishing results. Doesn't mean I don't see Lycoming engines failing left and right (because the suck), but overall durability and corrosion resistance really shines in those engines when I have to replace cylinders or perform other functions. I think I will add some CamGuard after I see the next oil report. I apologize for the format, I read the first sticky on the oil analysis thread and don't have a comparison yet to make a nice format.

The lead in the mix indicates to me that the previous owner/s may have used additives in the oil. Upon breakdown and inspection of the filter, I didn't see anything alarming. No massive carbon deposits and no metallic slivers or flakes like I've seen in my old Saab or various aircraft over the years. I will have a better idea upon my next analysis (I have 3,500 miles left before change). I've read that GM engines have more copper than others, and this being an LP9 I could almost understand that. Wrist pin bushings and such. Also read into seepage from the oil cooler? Around the Saab forums I've run into a few who have been changing the stock oil cooler to run remotely, which would be my preference. Difficult since the cooler also runs coolant through the oil cooler to decrease warmup time. Logical, but I'm still going to wait the 5 or so minutes for a proper warmup. Rapid metal expansion and contraction should be avoided at all costs. With a noticeable lack of other metals (looking at chromium mostly), I wouldn't quite say my bearing wear is a cause of concern, but if my next report comes out similar, I need to start looking at options.
