2001 Saab 9-3 SE
Mods: 3inch exhaust, stock boost(15.5psi)
Temps: July to Dec, temp range from +30Celcius - -1Celcius
Car was driven a little harder over this period, I was into boost at least once a day. Car is driven at least 26km 1 way each day and about 60/40 hwy/city.
L/100km: 7.0-9.0L/100Km
Additives: This is my first oil change since doing a auto rx clean/rinse cycle, this oil had 4oz maintenance dose of auto-rx. Also used the maitanence dose of Redline fuel clean SL-1(or whatever it is called).
I put a Amsoil Ea026 filter on (equivalent to Nappa 1773 in size) which allowed me to add 2 liters of oil to the sump. Total oil was 6 liters and this is why I pushed my OCI. This engine is known as a sludge monster, I have taken every step not to get sludge (updated PCV, New exhaust which moved the cat behind the oil pain and larger oil Filter). Some of you will say I should go much longer on my oil change, but even Amsoil only recommends a max of 7,500miles (12,000km) and 5,000miles for severe service for this engine.

Black Stone: Those oil rinses are a good idea for clearing out the residual wear and other things which gather and tend to accumulate in an engine. You have one of the nicest wearing Saab engines we've seen and we'd guess your engine has a long healthy life ahead of it. We do have a question about the silicon. It appears innocuous rather than abrasive, we'd just like to know its source. Do you have any silicone gaskets on the engine? Do you use an anti-foam additive? The TBN was 6.0 so you are good to go for more miles. Try 11,500-km for the next sample.

I was very happy with this oil and the engine stayed nice and smooth all the way to the end, I am glad I have another 6 liters of this stuff in my basement.
Edit: I have silicon vacuum lines all over the engine, this is the only place I can think that the silicon is coming from. The air filter was replaced this past summer.
