"The following conclusions are achieved, based on this research:

The wear occurred in the highest rate at the beginning of the break-in period. The wear rate then decreased sharply during the first hour. The wear reached its low steady rate after three and a half hours of engine break-in. Accordingly, the wear particles reached a high concentration in the oil after the first hour. Change the oil after one hour would reduce the wear in an engine."

It seems as if changing oil within the first 100-200 miles and changing to synthetic immediately might be a really good idea.

Some experts would have you make your first oil change in the 1st 50 miles. They also tend to belive that this is the most critical part of engine break-in and that the most effectiveness or damage can occur here.

Nice read Wes. Thanks for the link.
