This is encouraging news. I wonder if the "big" Corvette dealers are getting it first. This would make sense. Perhaps someone from Kerbeck and MacMulkin will chime in. I'm tempted to call my local dealer and see if they even know about the new oil. They sell only a few Corvettes each year.
That's what I did with both my local Chevrolet dealers. Provided the service manager with all the info and prompted them to reach out to GM. They are ahead of the curve, so to speak, now. Neither had any idea before I reached out to them.

Everyone should do what you did. I'd suggest sending the Mobil 1 flyer to your local dealer. It clearly states that Mobil 1 ESP 0W-40 is now recommended for all C7 MYs, and will probably prompt most of them to look into it.:
EDIT: Looks like the flyer isn't in this thread, so I posted a PDF file of it below:

Thanks for reposting it, Foosh. I did give all the information previously to my closest dealer, Novato Chevrolet. They actually received the first shipment of ESP 0w-40 oil last week. However, they won't do an included oil change with it on my 17 GS, because they have not received an official service bulletin from GM stating that the ESP 0w-40 is the recommended oil for older C7s. I was going to have to pay for the oil out-of-pocket. They wouldn't do an included oil change with 15w-50 either. So, I'm going next Wednesday to Rich at Abel Chevrolet in Rio Vista for a 15w-50 oil change, and then I'll move to 0w-40 at the end of the track season, assuming all of this has been sorted out by then.
If anyone else is able to get a dealer to do an included oil change at no charge with ESP 0w-40, please be sure to post how the dealer handles it.

Yeah, I think it's going to take a dealer who's willing to get a little creative until GM starts getting a bunch of noise from owners, which will prompt them to straighten things out and update all the old guidance. I suspect that will happen in the next few months, but big bureaucracies don't move very quickly.
However, it seems to me that a creative dealer could just use the 5W-30 part number for free-oil change reimbursement purposes, and then fill w/ 0W-40 from their stock. If there's a small price difference, I think most would be willing to pay the difference.

I would think that the retail price of the new(0w40) oil should be close to the old (5w30) oil. Am I off base?

There's no reason I can think of why it wouldn't be the same cost, except perhaps that it's new, and not available in retail outlets. If it is higher cost now that will change as soon as it hits Walmart and auto parts stores.

I've been running the European formula 0w40 fill in a '99 Mercedes-Benz E300 turbodiesel sedan for 5-years now.
My '06 Mercedes-Benz E320 CDI turbodiesel, I'd have to look it up which Mobil 1 synthetic was used.
My Ford 7.3 liter turbodiesel is still running 5W-50 Mobil 1.
Pep Boys had the least expensive European 0w40 when I bought last. A LOT less than my Mercedes Benz dealer, even with my trade discount applied.

Not relevant. The Mobil 1 "Euro" 0W-40 is not dexos™ certified. We're talking a new and different oil here.

Did the Mobil 1 lecture cover the differences between the European 0w40 Mobil 1, and the new 0w40 Mobil 1?

The only difference you need to worry about is that the new Mobil 1 ESP 10W-40 is dexos™ certified and meets GM specs for the LT engines. The old "Euro" version that's been around for years does not.
You're quoting a post more than a month old. The new oil is now being received by dealers, but is not yet available in stores.

Since hisvett was the one at the Mobil 1 lecture, perhaps he'll have some information he picked up on the new version of Mobil 1 0w40 to share.

It's all here on this thread if you really think getting into the minutiae is going to enlighten you. Just read it, but I suspect that's just going to confuse you more.
All that really matters is that you comply w/ GM specs, unless you just want to go rogue for the hell of it and test your luck.

Been doing some more reading on the differences between the existing 5W-30 Mobil 1 Dexos 1 and the 2019 0W-40 Mobil 1 which is Dexos 2 derived from Europe.
The primary difference is that the 0W-40 has much less Phosphorus content in the additives which helps extend the life of the emission system, specifically the catalytic converter matrix coating. However everything is a compromise, so the reduced Phosphorus content implies more metal to metal engine wear.
It appears that the main reason for the change is indeed, to negate having to do an oil change to 15W-50 racing oil for the track. However, if you are hard core with the track, you will still want to use 15W-50 as the 0W-40 is still a compromise for street and track.
So far I haven't heard anything about this 0W-40 that would make me want to switch because I would rather prioritize better metal to metal wear protection over catalytic converter protection.

So hopefully they don't decide to price 0w40 ESP like that.I guess the tricky thing is that when this oil starts being sold at Walmart and other auto parts stores, who is going to buy it? Just Corvette owners at first, until they also specify it for Camaro owners. But even if they do, that's still a very small market. So why would they take up a lot of shelf space and have it in the 5 qt jugs when sales of it will be much much lower than with 5w30?

I suspect Patman is correct.
Walmart might take a flyer on the new oil as a special incentive, package deal on the roll-out but if it doesn't move off the shelves, they won't come back for more.
They are all about inventory turnover.
Perhaps, if those who have been buying the original 0W40 consider this new formula equal to, or better than what they have been using, sales volume will work in our favor.

When I started using Mobil 1 0w40 European Formula, Walmart was still months from carrying it. I suspect the same will apply to the Mobil 1 Dexos II 0w40 formula.

Is there an official GM document that states the use of Mobil 1 ESP 0-40 oil for my 2017 C7?
My dealer has refused to use Mobil 1 for the routine 2 free oil changes within warranty. They wanted to provide me with Brand X Dexos oil. I refused. I just need some written official GM proof of the Mobil 1 requirement.

There are definitely tech bulletins that dictate they should use Mobil 1 for the included maintenance oil changes, do a search. However, I don't think there is anything official about the new 0W-40 ESP oil. The closest we have the are Mobil 1 flyer and Tadge posts that it's recommended, but it doesn't state it's included with the maintenance package.
Yes, that is what I understand...unless I can present my dealer with GM verification of the new oil standard I will not be offered 0-40 or 5-30 Mobil dexos oil... which is why I have paid for my 2 "free" oil changes at local repair shops.

They still don't show the new 0w40 ESP on the Mobil 1 website, but I noticed something interesting on there when I checked it out this morning. Their 5w30 ESP formula has the dexos 2 rating, just like the 0w40 ESP has, so technically speaking I think we should be able to use that formula and maintain our powertrain warranty just the same.
I know I mentioned this before, but the HTHS value of the 5w30 ESP is virtually the same as that of the 0w40 ESP, even though the 5w30 is slightly thinner (12.1 vs 12.9 cst at 100c) The problem is, you'll have a hard time finding the 5w30 ESP just like the 0w40 ESP is hard to find. They sell the 5w30 ESP up here at Canadian Tire but it costs $16.79 per liter! So that would be a $132 oil change (including tax) and that's for the smaller wet sump!
Anyhow, here is the link to the 5w30 and 0w30 ESP (the 0w30 doesn't have the dexos 2 spec)
