Break In Method: Hard or Babying It?

What he said. Break in is for the drive train not the engine. Engine rings and bearings get seated at the factory with one full throttle pull with break in oil.

Break in is still for both. Engine is not fully broke-in when you get your new Corvette.

No way GM fills the crankcase with break-in oil, then dumps it and refills it with Mobil 1. No way. The only break in your Corvette engine gets at the factory is when they drive it off the end of the line to the "alignment bay," and then hook it up for the diagnostics test before it goes out into the parking lot. And that's on regular old Mobil 1, and not at full throttle.

Yes it is. Been that way for decades.

Documentation? Based on what the factory tour says, the engine first gets fired up as it leaves the assembly line and heads to the alignment bay.
