Early oil change is not really meant to break-in the compression rings. Rings would break-in by the time engine has less than 50 miles on it regardless of oil change. Or it is completely missed by then.
This kind of fuel dilution is usually as a result of improper warm up/too much idling before sampling.
Classic "Blame the victim" response. Sure, idling can contribute to dilution but it is fundamentally a part of the design of most DI engines. My Honda is a good example: FF left in for 5,000 miles, lots of attention to proper break-in, no idling to speak of, still turns in >5% dilution after a 400 mile Interstate drive. Maybe none of this matters in terms of durability, but I can't help think most DI owners have been duped.
