First UOA on this vehicle, since I purchased it with 39,000 miles on the vehicle. The prior owner took excellent care of this car, and had all receipts to back it up. Oil was changed every 5,000 miles using SAAB Turbo Oil from the dealer (5w30 semi-synthetic blend). Because the 2.3L LPT of this vintage has had sludge problems, I performed a preventive Auto-RX clean/rinse program (used Shell Rotella T synthetic for clean and rinse) and have been using Auto-RX in 2oz maintenance doses since. I use either SAAB or MANN filters - this sample was filtered by MANN. These engines are notoriously hard on oil - the type of driving my wife does doesn't help much either - lots of short trips (maybe a half-dozen or so under 15 min). She does have at least two 25 minute trips every other day. Most driving is city and rural back roads - perhaps one extended highway trip every 4-6 weeks.
Blackstone's comments from this analysis:
"Other than a little gas in the oil, measuring at 0.5% of the sample, we didn't find anything much out of line in this sample. We don't consider fuel a problem until it reads above 2.0%. It didn't hurt viscosity, which was fine for a 0w/30. Wear accumulations were close enough to average to be considered normal. Universal averages show typical wear levels for this type of engine after about 5,200 miles use on the oil. The TBN was strong at 3.6, so the oil has plenty of active additive left. 1.0 is low. Try going 5,000-6,000 miles on the next oil. We'll watch fuel."
I'm pleased with the performance of this oil, and plan to continue using it - it's the specified weight for this engine, and is very shear stable.
Question for the board:
Are the Iron and Copper levels are anything to be concerned about?
I guess it's possible for enough oxidation due to short trips to spike the iron ... is the silicone high enough to cause this wear? Perhaps it was just a freak sample - I will send the next oil change in for analysis, and plan on keeping the OCI to 5k on this engine.
Thoughts?
