Vehicle in question is a 2008 S2000
My air filter was pretty dirty (as was postulated by Blackstone for the last sample based on the high silicon reading). I changed the air filter about 1/2 way through the latest sample, and the silicon reading dropped. Note that Virgin 300V already contains 10 ppm silicon, so even with the dirty air filter, the oil filter and air filter were performing admirably.
Also, I attribute the (unusually high for this oil) breakdown of the previous sample to the high temperatures. I was tracking the car in 100+ ambient temperatures. That sample included 2 track days (about 200 minutes of constant 6000+ rpm load) + my usual "spirited" driving.
The latest sample includes only one day and the usual drive.
Note that my daily commute is 7 miles of lights, and may include a few 2nd gear pulls... highway underpasses are tempting.
Virgin 300V for comparison.
Oh, and my first post here
