Healthy oil anlaysis - but high silicon

[N2897M]

Hey engine gurus,

Got my oil analysis back from Blackstone and everything looks good...except silicon. Came back at 32 ppm versus a previous average of around 6 ppm. Aircraft only flew about 15 hours in 5 months. 600 hours SMOH by Penn Yan in 2013.

Here are the lab's comments:

Silicon is a whole lot higher than normal, but without a simultaneous increase in the wear metals,
we don't think the silicon is abrasive or harmful. Some extra Dow-4 on the oil filter gasket, for example,
might be the source of the silicon. It could also be sample contamination.

Curious for further input and the typical sources of silicon in oil samples in addition to those mentioned above.

Thanks.
