Well,

It was the 3/16 up AND the full oil cannister. It was empty when I replaced the oil. So, it filled the cannister AND rose 3/16ths.

That's about a quart in volume increase after 30 minutes of engine time. Can't be good. But, maybe it's a really really bad float setting? Don't know, but I worry about bearing washdown and burning them up.
