I still question their levels of anti-foam "silicon."
I would not use more than 5ppm.
Mobil 1 racing oil VOA's, both 0/30 and 0/50 have more than 14 silicon. As do other high preformance and racing oils, some motorcycle oils also have high(more than 7) silicon numbers in their VOA. One thing I do, is look at a VOA and see what my UOA silicon numbers are, if my UOA silicon is about the same as the VOA then I know my air filter is doing it's job.
