Don't really understand all that. Looks more to do with oil than air.

59ppm of silica in engine oil indicate poor quality of air filter or silicone grease contamination.
silica might use as the anit-foaming agent in oil but will be lower than 15ppm.
Any value higher than 20ppm is inacceptable.

Still none the wiser. How does the Silica get into the oil, and where does it come from in the first place?
If Wikipedia is to be believed, Silica is used in the manufacture of high octane fuel.
Sorry only educated to O level and then studied at the University of life. Never really bothered with the white coat and test tube brigade.

iron level was higher but not alarmingly higher than expect. This make me think is has to be sand coming through the air filter rather than other silica source.
I did use sealant on the rocket cover before but i have got 2 oil change after that already.

en.wikipedia.org/wiki/...tamination
sand, dust, glass fibre are all silica....
gasket sealant, battery terminal grease. anti-foaming agent in engine oil, are siloxane, which is also silica....

Gasket sealant is silicone and I don't think that is anything to do with silica.

depends on the exact type of sealant but most of them contain up to 30% TALC by weight....
all those thing contain Si element...which is determined by IPC-Spectroscopy.....

Always thought about having oil analysed - how much for your lab as I couldn't find them on the web.
