I really don't think the reported blown engines are an attempt to deride GM. I don't see it as the Porsche event you describe either and hope it doesn't become that.
I do have a feeling that your simple oil filter change is not the answer.

Well thus far out of almost 40K the occurrence has been very limited to a few vehicles. With GM being under the microscope because of the ignition recall of the Cobalt I doubt seriously that if this were a real concern a recall would not have been issued immediately. Worst case scenario I could see is GM recalling the C7 for a oil filter change, perhaps to a new speced AC Delco or even a Fram or Mobil 1. This has not yet turned into a PORSCHE RECALLING $230K GT3s for a ENGINE CHANGE

He has a thread about his engine on this forum and whew there are so many posters bad-mouthing him for what he must have done wrong to cause it to blow.
Forum chatter should be taken for face value but I would expect some PR concern considering one of the most popular auto magazines has experienced failures in two cars firsthand. If there is an issue regarding failure frequency then I would like to at least be aware and my firsthand experience just happens to be seeing a white C7 blow a motor and catch fire at Roebling Road on August 16. I have no idea if the owner is active on these forums or not.

Wow
Silly waste of money but knock yourself out. Just do not even try to say that it makes any sense at all.

You are correct
I have a 2011 Z06 and for months there were 2 or 3 "experts" that went on and on and on complaining and crapping all over the LS7.
Got to the point where I actually spoke to a quality engineer that I knew from the BG plant and he confirmed that some bad heads got into the system and there were a few failures that GM replaced under warranty.
The real issue is that some of the failed engines were 2006 Z06s and out of the 5 year 100,000 mike warranty.
Really bad news for those folks......
I enjoy the forum but like any blog, there are always folks that like to create false alarms.
Take it all with a grain of salt,,,,,,

My Mercedes uses a drop in cartridge oil filter. It's top mounted and I don't spill a drop of oil replacing it during an oil change.

If you drive at 10/10 change oil filter after every track day

Now, if you know for sure that you have a bad filter (100% chance of being bad) or if you know with a probability greater than 50/50 that you have a bad filter, it would make perfectly good sense to change it because the new filter would have no worse a chance of being bad than 50/50 and you are likely to come out ahead by changing it - my 2 cents.

Car and Driver managed not just to blow up 1 motor, but 2. They also blew up a yellow one testing out at VIR. Cant blame the race track because the C7 was the only one out of 25 cars they tested. What is going on here ??

I changed my oil on my C-7 at 1000 miles and only use K & N oil filter, a little more expensive but worth it in my opinion and I like the wrench flats on the filter..... makes changing the filter so easy.
