I had the same problem, and after MANY hot miles, it didn't go away. There are only two things you can do to get rid of it. First, you can change the oil - but make sure it's HOT before you drain it. Most condensation occurs when the oil is cold and THEN changed. Second, you can add SEAFOAM which is a fuel/oil additive that you can get at any auto store, and maybe even Wal-Mart. I've used it for YEARS in everything from my car to motorcycles, to lawn mowers, to R/C airplanes.

Yeah, that’s a statistic sample size of 1, category “anecdotal evidence”, but there it is.
