I know that when I owned a 350Z it was common to think that guys that put synthetic in prior to 12 to 15 thousand miles could develop more oil usage. I know mine did. Has to do with the type of piston ring used.
I have forgotten more than I know..

Burning Brakes
Every year the factory that produces the engines has an open house. The engines are produced in St.Catharines, Canada (the Z06 and ZR1 are produced in the US with components made in St.Catharines) They have the synthetic oil put in them right there in St.Catharines. The engines are also fired up and tested using natural gas as a clean burning fuel. Engines that are going into Corvettes with a manual transmission are balanced right at the factory before being shipped to Bowling Green.

I am sure the engineers at GM knew what they were doing when putting synthetic oil in the engines from the factory... in fact over-all the whole series of LS engines are very very durable and reliable.

200-300k miles routinely obtained on these engines. I think we're fine.
I am thinking about changing over to synthetic for a '68 Pontiac 400 I have that was recently rebuilt and now how has a couple thousand break-in miles on dyno oil.

I thought the main reason people didn't use synthetic oils for break in was due only to the cost since you were going to take it out much sooner than the design life.

So I got this this newsletter from Corvetteforum and it had an article/advertisement about synthetic oil. Mistake #4 says using synthetic oil to break in your engine. Doesn't our cars come from the factory with synthetic oil when new?

C6 of Year Finalist (performance mods) 2019
Hey, IB (the owners of CorvetteForum) are consistently advertising that we need to put off-road truck mud tires on our C6. Just watch the second thread titles. At this moment the current second "thread" ad is for SUV tires. ("Looking for a reliable tire to get you where you need to go? The CROSSTEK® CUV is designed for crossover vehicles and compact SUVs.") Who is stupid enough to think someone is looking for SUV tires for their C6 or any generation Corvette for that matter? They are idiots when it comes to knowing their market. (Ooops, did they hear that? 
) I don't bother reading any of their crap.
As far as synthetic vs. dino oil, the C6 comes from the factory with synthetic. Evidently the engineers who designed the C6 know more about what the C6 needs than Joe's generic recommendations. Joe is correct though that when rebuilding an old engine it is better to use dino oil for the break-in. The reason is you use less accurately matched parts rebuilding an engine than the factory does when building a new engine. That means you need some wear to get them to fit better and dino oil gives more wear.
Bottom line - don't pay any attention to any ads coming from CorvetteForum unless they specifically say C6. Most of their ads have nothing to do with a Corvette and the products recommended will do far more harm than good.

Joe's a football guy who owns race car stuff. He's not even close to being on the same level as the GM engineers. The people he employs are race breeds whose main interest is ultimate power, not everyday engines for 250K mile daily drivers.
BTW, IB sells ads that blanket the spectrum irrespective of make. i.e. all forums see the same ad.

Don't understand comments like this. What is "typical" about 2-tone paint? I would say they "typically" make a great product, and every now and again they screw up.
My wife drives an Acura that is now 4 years old and several body panels don't match after a few years in the sun.
Maybe one of you could teach me something though. Are all body panels painted separately during manufacture? I was under the impression that the body was painted post-assembly. Is the fender painted separate from the body?

Flat tappet cams are one of the big reasons for using std oil during break-in. Most all modern engines use some type of roller lifter that significantly reduces the wear issues. Modern pistion ring materials and cylinder bore hatch patterns are designed to seat to the cylinder bore with synthetic oils.

Yep, and George Carlin used to say that they had discovered that saliva caused cancer------------ but only if swallowed in small amounts over a long period of time.

When I bought a LS6 crate engine from GM, my shop filled it with dino oil for all of the reasons previously stated...better break in etc...
This engine was installed in my 2001 SS Camaro.
Fast forward to when I bought the Z06 and learned then (2008) that it came filled with Mobil 1.
I asked the guy at the shop about this..his answer was...
"Because they break them in at the factory, they can put Mobil 1 in from the beginning."
Hmmmm

The main reason for the 500 mile "Take-it-easy" recommendation is for the gears in the rear axle, and to some extent, the gears in the transmission. Until the machining asperities are burnished into submission, they COULD initiate fatigue or spalling if highly stressed, say by 400 ft-lbs. of torque.
The engine is good to go from day one.
