Gentleben, I believe the 0-40 oil cap I purchased off Amazon was $13 and is a genuine GM part.

 

[GentleBen]

I'm sure that you are correct but the cap (GM 12680708) that I purchased was the one recommended by Harlan Charles, who is the Corvette Product Marketing Manager.

Unfortunately, the cap was supposed to be delivered today but the USPS says that it cannot be delivered due to an incomplete address. I will not name the supplier at this time as I will give them another (and final) chance on Monday to correct the error and send me a new cap while the original one is being returned to them via the selfsame USPS system.

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.

Could someone post a link or item number for the cap from Amazon? Thanks!

ACDelco FC265 is the oil cap that has the Mobil1 0w-40 dexos branding on it. The “dexos” is not visible in the photo of the product on the web due to the angle the picture is taken, but it IS on the cap. Currently priced at $10

0W-40 Mobil 1 - Oil Cap Part Numbers

The official GM part numbers for the new oil caps are:
• 12686472 – 2019 Corvette Stingray w/o Z51
• 12680708 – 2019 Corvette Stingray w/Z51, Grand Sport, Z06, ZR1
We checked around online and the new oil cap part numbers are starting to show up in various Chevrolet/GM official parts websites. We found them starting at the low price of $6.45 at ChevroletOnlineParts (The Stingray Z51/Grand Sport/Z06/ZR1 oil cap is priced at $23.12). These prices DO NOT INCLUDE SHIPPING. When I checked for mine, $6.45 + $11.00 shipping. I saved $8.33 by getting it at the local dealer a mile from my office.

JoeCT you would need the 12680708 cap. My Vette is a non Z51 and I picked up the cap at my local dealer for $9.12 out the door. They had to order it and it came in the next day.

Just a reminder to those of you planning on replacing your filler caps: the caps are NOT interchangeable between a base wet sump and the dry sump Z51, GS, Z06 and ZR1. As CruznCorvette noted in his post #28, they are different part numbers.

Here in the Phoenix are, I've found exactly one source for the Mobil 1 OW-40, that's Freeway Chevrolet. No other dealer or auto parts store has it, even the ones who are self-proclaimed Corvette specialists. I used it for the last change on my '15 Z51 and for the 500 mile oil change on the '19 Camaro. I'll get some more as soon as the Z06 arrives as well; maybe lay in some inventory at home. I'm wondering if this thin supply line will improve anytime, and what if the C8 spec is for something different?

Mods - Please remove if repost.

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,

@ Amazon.

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.

Did 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.......

Do you know the GM part number for the
Mobil 1 0W-40 cap? I only see 5W-30 caps

I 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.

For my ‘17 Grand Sport I found it on Amazon. The same cap will fit any LT1.
