I would be the first one to defend what you are saying in regards to break in, but keep in mind that these engines are pretty old school in design, construction, and materials.

Modern engines are also assembled with modern techniques, etc, and are often sent from the factory these days where there is minimal break in time required and with synthetic oil in them.

From my own experience, trying to break one of these in with only synthetic will result in a much longer break in period and a higher level of oil consumption during the break in period.

By all means, if you want to give it a go with the full synthetic break in, go ahead. I was just offering my own 2 cents. I gave it 500 miles on T4 and it still took about another 1000 miles with 15w40 T6 before I could confidently say my break in period was done.
