I'm a newbie to the forum, and was hoping for a little insight on oil analysis interpretation. I posted this on the oil analysis forum first, but it was recommended I might try it over here.
I built an experimental aircraft with a XP-IO360 engine. It was broke in using straight mineral oil to seat the rings for the the first 48 hrs, then changed to the additive containing Aeroshell 100 plus oil. After 42 additional hours I changed the oil, and sent a sample of this oil for analysis to Polaris Labs, and got the results back showing a high amount of lead.
Since this engine is run on 100 octane leaded aviation fuel, I would expect there to be lead, but I was wondering if anyone in the forum would know what the normal amount would be, and for that matter what the norms would be for all the wear metals, contaminant metals, multi source metals, and additive metals ?
Thanks!
