Just received my lab report on the last oci.
Shell Helix Ultra 0w-40, 10782km (6735mi) in a Saab 900 turbo 16V (B202L).
https://turboseize.wordpress.com/2016/08...-turbo-b202l-2/
Saab 900 turbo 16, model year 1985. Engine code B202L. Total mileage 591006km, which equals 369148 miles. Engine rebuild at 410000km/254700mi due to defective LH-jet (did not enrich enough under full boost and killed a piston ring).

* the german word was "Schmutztragevermögen", hope I translated that right.
** the lab has introduced the "Rußindex", an in-house tool to check for soot in
gasoline oil, as soot from direct-injection engines will not show correctly in the
standard test for diesel oils
Here is the original. On the left: Shell Helix Ultra, then Aral Super Tronic, to the right Mobil1 "New Life".
