Dave, suggest you use Blackstone Labs in Ft. Wayne IN for your oil analysis in the future. They don’t toss out generalizations using words like “seems high” they list the data for each element just like a physician lab report would do on your blood draw so you can see the baseline vs. your blood- or in this case- engine oil. If they see something suspect they call or email you and ask for additional data to gain perspective. They also don’t force you to consult forums for analysis advice, yes there’s a lot of experience here, but you’re paying for this oil analysis dadgummit. They also won’t just tell you to consult with your engine manufacturer for anything suspect or out of tolerance, not that Rotax wouldn’t be the ultimate authority, they are, but Blackstone will provide professional analysis and recommendations for those elements that are suspect or out of tolerance. They will also call you 24/7 if they see something of immediate safety concern.
