I change the oil/filter right at 1000 miles on EVERY car I have owned (even pre-owned ones). My 2014 Stingray is sitting at 957 miles on it and will be taking it to my dealer this week.
It may be a waste of resources, but it makes me feel better.

My dealer is one of the will not change the oil until DIC is at 22% under the 24 month free scheduled maintenance plan included with the car's purchase. Good enough for GM, good enough for me. Satisfies warranty requirements.

Just a case of bad mojo IMO. Faulty oil filter causes engine to break. Too bad it happened on a long term test car, where it can be reported as "Car and Driver Uncovers trouble with Corvette Stingray's LT1 V8"
Just another case of a sensational headline that (in our sound bite culture) implies one thing while the facts reveal something entirely different.
Unless we start hearing this from a number of sources with the same causation, I'd not concern myself.

Looks like the cause was a defective oil filter shedding a piece of metal into the oil stream. So by changing from a known good filter to an unknown one, you just doubled your chances of the same thing happening to you.

If the filter, in fact, was the cause of the problem, I would definitely like to know the batch number of the filter and if all with that batch number are being pulled from the inventories.

It certainly doesn't hurt to do a quick audio/visual inspection of the filter. Several years ago I picked up a couple of AC/Delco filters for my 6.6 Duramax and I noticed one rattled when I picked it up. I shook it in the store and a couple of little fragments of metal came out of what should have been the clean side. I have made it a habit of checking filters closely since then. I really like the open construction drop in cartridge filter in my Cadillac 3.6, I wish GM used those for more of their engines.

Goes both ways..
I have had some pretty nasty looking oil filters new in the box, unless you cut it apart its hard to tell. Either way, I'll still use AC delco filters and let GM worry about the bottom end staying together for the next 4.5 years

C7 Engine Blows in the Car and Driver Long-Term Test Car
Hell, even the best of the best have a bad day sometimes. That appears to be the case with a manual Z51 Corvette loaned to Car and Driver magazine, which recently reported that the engine blew on their long-term C7 at around 6,000 miles.
Read the rest on the Corvette Forum homepage.

Had the dealer change the oil and filter this morning. Car has 1,500 miles on it, should have changed it out at 500 miles. Was willing to pay for the services but dealer ( Lakeside Chev, Rockwall, Texas) , said its on the house. 
it may still blow but it won't be because I was running the original oil and filter.

Out of almost 38,000 C7s we now know of 2 that have blown their engines. Even if there are a few more I'm not worried.
