Clip from Road & Track on the "break-in" subject (bottom of page).

Mobil's response was that engines break-in just fine on synthetics, and that
any wear point in the engine significant enough to be an interference, and
thus susceptible to rapid wear, would be a wear point no matter what
lubricant is used.

Redline, on the other hand, has found it best to recommend a mineral oil
break-in. Occasionally an engine will glaze its cylinder walls when
initially run on Redline, they say, so by using a mineral oil for 2000
miles, verifying there is no oil consumption and then switching to the
synthetic, glazing is eliminated.

Can someone explain to me Mobil's response?
