Thanks for the info. Comparing the data between the current FS 0W-40 and the ESP, there are definitely some differences included less Zinc and Phosphorus content (as expected), but it is dexos, so for those still under warranty the ESP is the way to go. Curious to hear what the oil connoisseurs (cough, cough Patman) think of the ESP compared to the FS.
So far everything I am reading about this new 0w40 ESP looks good, and I'm very anxious to run it in my car when it arrives at Walmart. I was hoping it would arrive soon enough to do it on my first oil change, but I can't wait until summer to do my first change, I'm planning on doing it in the next few weeks actually. So I will start running it in my C7 on the second oil change.
One thing that gives me confidence in this new 0w40 is the fact that it's been specifically designed for our Corvettes. It's not often you get an oil company that makes an oil specific to one engine like this. That alone is huge! Even though M1 5w30 is a great oil that has served Corvette owners well for many years, I do believe the LT1 has different needs, with it's direct injection and AFM. Those two things place different demands on the oil than the LSx engines did. I also like that this oil has an HTHS value of just over 3.5, vs 3.1 for 5w30. That provides a bit more protection under hard usage and high oil temps. But it's also not too thick that it will hurt MPG either (most probably won't even notice a difference at all)

The dry sump itself hasn't changed, so the 0W-40 cap is exactly the same as the 5W-30 cap.
The same applies to the wet sump cap, which does not fit the dry sump. However, the valve covers haven't changed either so 5W-30 and 0W-40 caps will be interchangeable on them as well.

Yes, but folks here are looking for the new 0W-40 cap because of the new oil recommendation, which are back-ordered.

Called my dealership today to schedule my 500 mile oil change. They have no clue about 0W40. They said that if Mobil 1 recommends it, that doesnt mean Chevy does. And if I wanted 0W40 would cost me because they are only putting in what GM recommends and that is 5W30.

Does this mean that going 0W-40W oil in 2014-2018 Corvettes that have 5W-30W oil as the recommend oil that the Warranty is still in effect?
Based on everything I have read and forgetting the cost I would prefer the 0W-40W oil
if someone could tell me no impact on the Warranty.

if this is what you are referring to, no where is the Warranty issue addressed?
If someone can tell me Tadge is speaking for GM/Chevrolet and they will back his statement rather than the warranty book with 5W-30W in it that great, again I want to use the 0W-40W but not interested in dealerships telling me you go by what is in your warranty book.
Tadge answered:
Yes, the new Mobil1 OW40 Dexos 2 oil (Mobil 1 ESP Formula 0W-40) is also the recommended oil for all C7's prior to 2019. This oil was specifically developed to meet all of GM's performance requirements during engine dyno testing, vehicle road testing and performance track testing including the 2014-2018 Corvettes (all models). The Multi-grade Mobil 1 ESP Formula 0W-40 synthetic motor oil has many benefits including exceptional fast oil flow at startup along with low temperature pump-ability and exceptional viscosity/performance characteristics at high-temperature and high-RPM operating conditions. We are still refining our recommendations for the LT5 in the upcoming ZR1, so they may differ.

Tadge Juechter is the Chief Engineer of the Corvette Division of Chevrolet, so yes, he is speaking for Chevrolet and GM on this matter. Saying it is recommended for all C7s back to MY1 '14s obviously means it complies with the warranty. You can use either dexos™ certified oil and remain warranty compliant.

Thanks, after talking to GM/Chevrolet and getting a response to stick with what is in your warranty booklet, I was getting concerned that the 0W-40W would not be accepted as suitable for the purpose of the warranty staying in effect.

Consider the source. I don't know who you talked to, but phone reps, dealer sales, or even service people are often not terribly up-to-date. The safe thing for them to say is "read your owner's manual."

I went to the local dealer, who is heavy into Corvettes, to inquire about ESP 0w-40 M1 for an upcoming oil change.
The were well aware of the product but have not been able to get it in for service or sale over the parts counter.
Their supplier could not give them a date for shipment at this time.
They have 5 '19s setting on the floor and are not sure how to provide the required oil changes once the go out the door.
Maybe the shipments will flow. I wonder if you brought some empty jugs to the Bash you could get them topped up at the factory.

Yeah, a lot of people aren't going to be happy when all those sold dry sump 19's being delivered now need a 500-mile oil change in a couple of weeks. I won't name names, but I haven't found any dealer who says they have it yet. I'm due for a 500-mile change in 80 miles.

I think it's going to be a step up from the current 0w40 FS formula, which has actually gotten a little bit worse than before, as they've dropped the BMW LL specification and it doesn't have as much PAO in it's base oil either. I was running the 0w40 FS in my wife's BMW up until last weekend, and then switched it over to the European made Castrol 0w40 (which does have the BMW LL spec)
So far everything I am reading about this new 0w40 ESP looks good, and I'm very anxious to run it in my car when it arrives at Walmart. I was hoping it would arrive soon enough to do it on my first oil change, but I can't wait until summer to do my first change, I'm planning on doing it in the next few weeks actually.

According to the technical properties for this oil, do you think this oil would be acceptable for for extended drain intervals? I'm thinking other cars could use this oil, too.

The UK version of this oil does meet the BMW Longlife 04 but it's not clear if the reformulated version for the US is going to have it or not. If it does have it, then you could safely do extended intervals (I'd go no higher than 15k though) But if it doesn't have it, I would keep it below 10k.
