Just changed the oil and received a oil analysis back. The results show high levels of Silicon (21ppm). 213 TT and 25 hours since last change. Using Shell Aero-4 oil and only auto fuel.
Have only flown 25 hour this passed year due to extended travel.
Does anyone know what would cause this high reading?
