Filter was Wix. Driving pattern was my normal 200-250 miles/day, a mix of city and highway. There were no long highway trips.
The injector nozzles were replaced with Kerma (Bosio) PP520's on Feb 2nd, about two weeks before the Feb 17th oil change. So new nozzles during the entire interval.
Soot is high but trending down. Silicon is just slightly elevated. Copper and aluminum a bit high. Viscosity pretty high, as in recent tests.
Next oil change in early July.
