Hey - I'm still new at the whole airplane ownership game and have a question on oil analysis.
I have an Aero Sport Power IO-375 on my newly flying 7A. In April or so, I drained the perservative oil and filled it with Aeroshell 100 mineral oil.
I ran this oil for the first 10 hours then changed the oil. I did not send that oil in for analysis (I figured that it would be high in metal content due to breaking in a new engine)
For the next 15 hours, I also used Aeroshell 100 mineral oil, but went ahead and sent in a sample to see how thing were going.
As you can read in the numbers and the summary below, the folks at Blackstone labs were a bit suprised at the very low metal content in the oil given the very low hours on the engine.
I am assuming that this is good news and that the engine was pretty much broken in during the first 10 hours.... am I interperting this correctly or is there any other reason why the metal content would be so low after only 25 total hours (15 on this oil)?
Thanks,
Jason
