Gentleben, I believe the 0-40 oil cap I purchased off Amazon was $13 and is a genuine GM part.
Sorry to tell you this, but the Mobil 1 0W40 motor oil on the Costco website is NOT the Mobil 1 0W40 formulated for your Corvette. It is the European blend designed for use in European brands only. The Mobil 1 0W40 designed for the Corvette is ESP 0W40 and has Dexos on the label. I have attached a photo of the label on a quart for reference. DO NOT use the European blend in your Corvette. It is not Dexos 2 certified and doesn’t have the same temperature rating as the ESP 0W40.Available at Costco.com $38.69/6pack. Get an extra $10.00 off special price through 4/28

The new recommended oil for the C7 Corvette is Mobil1 0w40 Dexos 2.
So after doing some online searches and calling a few places, no one carries this weight of oil, Walmart has the european spec for Porsche, BMW, etc. "Not for the C7".
So I reached out to Mobil1 and inquired when will this product reach the supply chain of Walmart, and the parts store chains.
Here is their response - Thanks for writing in. Can I assume that you have a (2014-2019) Corvette? The situation with the ESP 0W-40 is that at the moment, it's a low demand item and it is only for C7 Corvettes. As such, it will be difficult to find on the shelf. However, if you give the part store our Mobil part number 123875, they will be able to order it for you. It might save you some time if you ask to speak to a manager. They should have a better understanding of their company's supply chain system with regard to new products that they've not yet carried in-store.
Thank you for choosing Mobil,

Due to the confusion between the ESP European blend, which will damage your Corvette catalytic converter, and the ESP Dexos 2, recommended for the C7 non-ZR1and factory fill on the C8 Stingray, Mobil1 has rebranded the ESP Dexos 2. It is now Mobil1 Supercar. The name Supercar is in an orangish-yellow rectangle.@ Amazon.
Do you know the GM part number for theDid the spring oil change on Mr. Cash today. Great day to spend in the garage, 10” of wet sloppy snow the last 2 days, hopefully Mother Nature will turn the page for us. Anyhow, I used up my “free” oil changes from Chevy and did this one myself. Relatively simple once you can safely get under the car. Went the 0w-40 Mobil 1 ESP route with a PF64 Delco filter. Ordered all off of Amazon along with the new oil cap which is a GM part. Thanks to all who have given out good information and advice for those of us not as schooled in all things Corvette. Yet.......
Gentle BenI had a 0W-40 oil cap on my Z06 when I took it to the local dealership for an oil change. According to the receipt I was given they used the 0W-40 oil that I directed to be used. They charged $9.30/quart for the oil (GM 19353135) but somehow the oil filler cap had magically morphed into a 5W-30 oil cap when the car was returned. My fault for not checking immediately and it was over three weeks before I noticed the substitution. I'll still go to that dealership but both I and the service writer will agree that the 0W-40 cap is on the car when the car goes in for service and when the service is completed. A new 0W-40 oil cap costs $38 and I'd rather not buy another one.
