i think on factory new stuff you do the same but can skip the 20 minute oil change.

But I broke mine in on the dyno and then changed to synthetic after 200 miles.....And then went all out!

There will be a lot of opinions...
I've built a small handfull of two stroke motorcycle and snowmobile motors. My break-in for those virgin motors is a good amount different than if you were to buy a vehicle like a motorcycle or car/truck. With some of these motorcycles, and I hear some of these new vehicles - either the engine is run on a engine dyno, or the vehicle on a chassis dyno - they're supposedly "put through their paces" to make sure everything is in order. I'm quite certian my motorcycles get bounced off the limiter right at the factory.
I've broken in two high performance motorcycles (with less than 4 miles on them), and I've broken in three later model Chevy's. A 4.3, a 5.3 and this 6.0. All new, off the lot with around 4-5 miles on them.
I babied a motorcycle, and the 4.3 truck. I will never baby a new vehicle again. The motorcycle burns oil when it's getting spanked, and the 4.3 retired pretty early, also with oil consumption issues. Could have been coincidence... maybe not though...
Right off the lot, I put the pedal to the floor in the 5.3. That motor ran absolutely perfectly, with hardly any oil consumption up to about 40K miles, where it was traded for this truck. I ran this one hard too, and I'm in the same boat as above... little to no oil noticeable consumption.
When I say 'run hard' I don't mean doing a night of drag-racing... but very 'hearty' squirts of gas. Some long, some short. Different gears/speeds are good to.
I changed my oil in both trucks at 500 miles. I don't think it was necessary at all. Very clean, and no shavings. (unlike the motorcycles)
