Still missing the point. The point is that there could be foreign objects in the system that could cause damage when it was built. By flushing the oil after a few minutes of running, the oil picks up and suspends those objects so they will be removed when the oil is changed.
Then refill and run for the 5 hour break in. Break in does contaminate oil as well, but with minute particles from wearing in, not the 'big' stuff from manufacturing.
I think those venerable red engines are built in China too. When I did my break in on my Champ, the oil did not have any filings in it. Change is happening in the generator world. Red and Blue better be ready.
