Air Venturi AVA regulator issue

Regarding adding silicone oil to the fill port, I tried this approach in my first PCP but when I eventually took it apart, I could not find any evidence that the silicone oil atomizes and migrates through the system. There was a little bit just beyond the check valve on the air tube walls but everything else was bone dry as best I could tell (e.g. wiping a finger on metal surfaces and then observing the surface with light reflecting at a shallow angle).

Granted it won't hurt anything.
