I know that Mobil 1 0W40 Dexos 2 is required in the C8. However, it appears that it is not readily available. In a Goggle search I cannot find it for sale anywhere.
Are any other Mobil 1 grades such as 0W40 European Car Formula or 0W40 ESP acceptable??
Where are you buying 0W40 Dexos 2?
Mobil 1 European 0W-40 is not compatible with the C8, nor is is Dexos-approved. Please see below:

You can buy it from some dealers. Unfortunately I have found 3 dealers using the wrong oil which is why I change my own
Thanx for the heads-up re AutoZone. They had a deal where I got fifteen 1-qt bottles of Mobil 1 ESP 0W-40 and three Mobil 1 M1-113 oil filters for $134.64 w/ free shipping.

Wow that is a really good deal! I better go check that out for myself. I've switched my vehicles over to Fram XG filters from the M1, but at that value I can certainly accommodate changing back
*EDIT*
Found that deal and I'm ordering it for myself now; appreciate the heads-up! I might order 15 qts since it's enough to do 2 complete oil changes...I'll just be swimming in oil filters at that point $133.11 total shipped to my door for 15 qts + 3 filters.
This site has a list of Dexos licensed oils: https://www.gmdexos.com/brands/dexos2/index.html
A specific brand is not a requirement. If you trust this list there are two brands that would work.

My shipment from AutoZone arrived and they actually sent me Mobil 1 0W-40 ESP x3 along with the oil filters.
Is this oil truly an "upgrade" vs. our factory oil or should I exchange it?
The M1-113A filter appears to have been redesigned since I last saw one, now with larger drain holes. Still not as large as the Fram XG's, but the inside tube louvers actually look better. Overall, the XG canister is slightly larger, but the M1 is heavier.

For me, the biggest controversy with the M1-113A oil filter is how they can specify it for the C6 with a lower bypass pressure but also for the C7 and C8 with a higher bypass pressure requirement.
Is the same Fram XG listed for the C6, C7, and C8 also?
I know Champion Labs used to make the M1 filters but I believe Mobil 1 switched suppliers.

Fram XG12060 is specifically for the modern GM vehicles requiring the higher bypass pressure. The bypass is rated 19-25 psi. This is my preferred filter for C7 & C8 applications. Fram does not list it for the C6. It also is rated 99% down to 20 micron while M1 is rates 99% at 30 micron. I am getting more annoyed they sent the wrong oil and may go return it... I want the stuff specially engineered for the C8.

the X3 is the best oil M1 makes, it meets the stringent Porsche test levels and certification and is dexos approved. Ive been running it for a few months now. Superior to std fill esp, keep it and consider yourself lucky....most people dont know about it yet.

the x3 is a better oil.
Id use oem filter only under warranty. If the oem oil filter shows a failure you're still fully covered on an engine replacement. If an aftermarket oil filter fails they would not have to cover you.
Heres the last brand new m1 filter i cut open anyways...
Well that filter looks like a steaming pile of garbage! BITOG is big on the Fram XG filters so I think I am going to stick with them. Honestly haven't seen or heard anything bad about them; no horror stories anyway.
For anyone who is running the M1 filters (I used to on my C7), here is what I was directly told by Champion Laboratories (the maker of the M1 filters) back in 2017:
The Mobil 1 M1-113 or M1-113A both use a 22psi by-pass valve.

I ended up returning 2 of the 3 M1 filters to my local AutoZone and got about $30 back. End of the day not a bad deal considering I got 15 quarts + 1 filter for about $100! I kept one and will use it to give it a shot since it's the new redesign with larger oval drain holes. My local store had the new box on the shelf, but the filters inside were still the old style with smaller circular drain holes. Here's a comparison of the "new" M1-113A vs. the XG12060 (original style with metal screen backing on the media):

Yep, I have a similar email from them. It just seems strange that they list the same filter for both the low and high bypass pressure requirements of the C6 and C7/C8 Corvettes. Depending on you the specifications are written it could be possible for the requirements to overlap and have a single bypass design meet both requirements but we aren't privy to that information.

Mobil 1 also has a warranty when using their filters. So if GM were to deny coverage of an engine failure due to a M1 filter failure then you would have documentation that the failure was caused by the M1 filter. Additionally, we have documentation the the M113A meets the GM requirements. But this is highly unlikely, and I don't think GM would throw their strategic partner under the bus.

Exactly. Why in the world would anyone want to go through that when the OEM filter is readily available right?
Think about the actual situation. GM blames the oil filter and denies the claim. Then you deal with M1 and the M1 coverage states they will only cover a failure if its proven their filter is the cause. So then M1 says its not their filter. What are you going to do then? Hire a lawyer?

You use the oem filter you avoid all of that.
While possible, this scenario is extremely unlikely. I take a lot bigger risks then this.
I have never heard of GM denying warranty coverage because a failure was caused by an aftermarket filter that met GM specifications and the filter manufacturer didn't cover it. If you have any links I'd be interested. And, if GM did deny coverage, they would have to prove that it was caused by the filter failure, not just the fact that it wasn't a GM filter. This is the very reason for the Magnuson-Moss Warranty Act. If they did state the the failure was caused by the filter then you have the proof for Mobile 1 was responsible. Yes, you could get stuck in the middle of this. You could also be struck by lightening.
