This is the first mention I've ever heard of an engine taking 30,000 miles
to break in.  Except for chrome rings which I don't believe are used much
any more, I thought break-in was as complete as it was going to get at 8-10k
in the worst case.

The reason this is of interest to me is my new engine has 18k miles on it
and still uses a quart of oil every 8-900 miles.   An amount I consider as
evidence that something didn't seat.

After usual gentle break-in I'm down to trying 40 wt non detergent per the
rebuilders suggestion.  Any other ideas?
