If the K&N pre-filter and/or cone filter has any silicone content to it, that might be the reason for the 15 ppm of silicone. Otherwise, it could be excess dirt getting past the air filter, so you may want to check that out. All of your engines wear metals read below the universal averages ,which are based on a 3500-mile oil run, for this type of engine. The TBN registered at 6.1 ,loads of active additive remaining in the oil, - 1.0 is low. No fuel, water or anti-freeze was found and the viscosity measured in the upper SAE 20W range @210F for your oil mixture.
I am pleased that the silicon levels dropped with the addition of the oiled foam K&N installed over the K&N cone filter. The air must be getting filtered a little better. Chromium went to 0 so that sounds like less ring wear from dirt. Silicone may be still leeching out of the RTV pan gasket and I have noticed a few small chunks of RTV that have come out when draining the oil.
The oil was dark brown in color when changed. I will continue to change the oil and filter at 5000 mile intervals even with the high TBN still there.
This car is driven in a spirited manner on a 70 mile a day commute with a mix of interstate and town driving delivering 30 to 34 mpg. There were 2 short 5200 rpm top gear 120 mph+ runs on this oil change. The thin oil blend is protecting the engine well according to the UOAs and the throttle response and turbo spool is very crisp. Based on these results I feel comfortable running a thinner oil in an older engine and will use a similar blend in our other vehicles
