explanation of oil additives
(OP)
Analysis of an new oil sample used in a high performance gearbox application highlighted the following main elements: -
silicon 1200ppm
sodium 15ppm
Boron 62ppm
Moly 970ppm
Obviously these are due to the additives in the oil, could anyone work out the likely additives being used in this oil from this admittedly very basic information and the reasons for their presence (ie anti-foaming or anti-friction purposes).
Thank you in advance for your assistance.

..then I noticed it's for a gearbox, not an engine, and decided I didn't know much about that topic.
RE: explanation of oil additives
The application is a race car gearbox and the grade has a particularly low viscosity to reduce efficiency losses.

Siloxanes have been known to have high spreading (wetting) rates on metal surfaces even when exhibiting high viscosity.
