Today I received the results of the Blackstone analysis from my third oil change. I love how they say I'm "borderline inactive". True I only averaged 5 hours per month as life's been pretty hectic lately... Now I have something to show my wife, "See! I'm not flying enough!!" :)
Left Engine:
ADAM: Thanks for the note on the ferrous metal in the screen. That's always cautionary, and it's something to monitor. Wear metals were a little on the high side for only 20 hours on the oil, but iron was the only metal that really increased. Universal averages show typical wear levels after about 40 hours on the oil. This engine averaged about 5 hours per month, which is borderline inactive in our book, so that might explain these metals. Silicon was on the high side again, but if the air filtration system is okay, it's likely just a harmless sealant. Check back in another 20 hours.
Right Engine:
ADAM: This right hand IO-520-E looks a lot like its twin, which is what we'd expect for two engines in the same aircraft operated by the same person. You found ferrous metal in this screen as well, so we have to treat this as a cautionary report, though the fact that both engine look so much alike is a good sign. Wear actually looks a little better this time, so hopefully we'll see even more improvements in the next sample. No fuel or moisture was found and silicon is heading in the right direction. Stay vigilant and check back in another 20 hours.
