The right motor oil

LDB,
Oh, I completely agree it's not worth the trouble for JJ to drain out the 10W-30 someone ill-advisedly put in his car. The odds are greatly in his favor, and he's more likely to be struck by lightning than have an engine failure over the next few thousand miles.
I'm just saying, I'm going strictly by the book on dexos™ and every other GM recommendation. It makes no sense to do otherwise, to save a few pennies. I don't want to give GM any excuses in an engine disaster scenario, regardless of the odds. That includes having all my routine services logged in GMVIS, so I don't have to mess with showing receipts or any other thing that might be questioned. Doing so also makes a vehicle easier to sell because any prospective buyer can just have the service history looked up by VIN.
As I said, I agreed with everything you said, I just had the one minor quibble that I articulated.

I am going to be doing all of my oil changes so in the rare event of an engine failure I will be keeping every receipt of the oil and filter purchases. In addition to this, I plan on continuing the practice of getting my oil analyzed after every interval too. So GM would be able to see the dates and mileage of each change as well as the proof that I ran the correct oil when they see the data from each report.

That works too, and I used to do all my own changes, but I'd rather spend my time doing other things now, and let GM do the record keeping. While the oil change itself is easy, I'm tired of the hassle of old oil disposal, etc. I think most prospective new owners are also more comfortable having GM tell them all services has been strictly complied with, rather than me handing them a pile of paper saying the same thing.
It's easy to avoid an over-fill on the dry sump by giving strict instructions to only fill w/ 9qts., and provide me the extra quart to adjust the level later. That's been noted on all my past invoices, and in 4 changes I've never had an overfill issue. My car actually came slightly overfilled from BG. However, with the low revs recommended in the first 500 mile break-in, it's not an issue.

Mobil 1 0w-40 ESP is recommended oil for all C7's prior to 2019 per Tadge. I will be changing my oil in my 2016 C7 as soon the weather gets better. I got 2 cases = 12 quarts of Mobil 1 0w-40 ESP from Speedway for 54.99 a case, 10.00 discount for first order, free shipping, plus tax = 9.07 a quart.

That's one heck of a deal. Isn't the 0W 40 $10+ a liter?

Are you sure they used Mobil 1 0W40? Sounds like it is too good to be true.

Always cringe when these threads start with “my mechanic did/said...”. The obvious answer is to follow GMs guidance.
In this case likely he just buys 10W/30 in bulk drums and tells all his customers your GTG. Much easier than carrying multiple differnt viscosity oils.
