Had my first oil change today..Only had 2600 miles so I PAID for the change...$183 ,,,,,Wait till next year for the free bee....Everything went fine and cked. oil level when i got home and it was fine...Since the vette only takes 7.5 quarts I asked If i could have the 1/2 quart left over and they said fine...So If i get low I can add...They use quarts and had the supercar oil...
Only took an hour....
Ready for another year and plan on putting more miles on her
Very pleased with the experience..
So the dealer actually used 1 qt bottles for the change? Usually they meter the oil from a larger container such as a drum.
If that is what they are doing (from a drum), you probably aren't getting Mobil 1 0W-40 Supercar (or ESP - the prior name). You're most likely getting generic Dexos 2. Mine always uses bottles for the Vette - I can see exactly what they are using.
I changed the oil myself and it took all 8 quarts to bring the level to the mid-point of the hash marks. I let the oil drain from both the filter and the drain plug for a very long time until it completely stopped dripping. I am surprised that accounted for an extra 1/2 quart being drained.

They might not be packaging the oil in bulk yet given a newer formula, but for a commercial unit like a dealer to be working individual 1 qt bottles makes the oil more expensive throughout the supply chain.

Most dealers don't service enough Corvettes to justify buying that particular oil in bulk. I have mine done at a Corvette Signature Dealer and they use bottles. For other vehicles, they use bulk.

That was the problem with my two C7's and why free was not worth the risk to me at the large Chevy/BMW/Mercedes dealer in town so I did my own. The usual Newbie tech working the Oil Change Bay (hard to find mechanics today and that job may be filled with a person flipping burgers the month before) may well use the oil in 55 gallon drums the boss bought from the Low Cost Supplier! There are many dexos 1 approved oils that are on the GM approved list. Some even blends NOT full synthetic!
In addition that Newbie tech, rather than fill the C7 (or C8) the proper way (per the C7 4 volume service manual and what I have been doing for ~70 by the oil level mark) might read what the service manual says is an ESTIMATE in a table. With the C7 and C8 have to heat the oil to 175 F to measure the level. Takes time.
Many working the oil change bay may NOT want to go to the parts department and lug 8 quarts of oil back to their work area. Just dial up whatever # is in a table and fill cold with whatever oil is in their work area! Easy to overfill!
Unlikely from drums unless it's a very large Vette dealer and IF Mobil supplies ESP 0W-40 or the latest acceptable oil for the C8 in drums.
Luckily found a small dealership with a great Corvette tech who is the only one who works on Vettes, oil changes etc. He filled my C8 from quart bottles of the right stuff. After the oil was @175F, he checked the dip stick twice!!

Great that the dealer did a good job with your oil change. If they do something like an oil change well, hopefully they will be a good source for other repairs that involve more complicated work.

I had sent you a pm a while back but maybe you did not get it?
But yes I called days and they were real nice to me but they were having trouble getting the oil
I went to Hardys cause they said they had it and they are closer to me...Did not make an appointment..just use tue-thurs. to go. I got there at 7:25 and was 4th in line..Took only an hour...
Be sure to ask for that 1/2 quart....when I asked they said why not and the guy brought it around..Supercar oil...cool..
I think either place is ok...The mechanic said he noticed my low millage and understood my reason to get the next year the free bee.
Good luck....
ps. They also did a factory update on the battery software??? Did not ask about it but they said there was a recall on it----

GM has 2 packaging types available to dealers both under the old name and the new name of it. 6 pack of quarts, or 55 gallon drum.

I may have missed your message. I've been dealing with Long Covid since June and the brain fog is unbelievable. I'm glad to see that you went to Hardy's. I tried to get Day's service department on the phone unsuccessfully three times yesterday so since I get my other two trucks serviced at Hardy's I called them and asked if they had a certified C8 mechanic. They do so my C8 will be there tomorrow getting the oil changed. I'm glad the mechanic there knew about the extension to two years for the free oil change and DCT filter that GM gave us because the Service Writer I spoke with there was confused about it. I really like the people at Hardy's and am glad I can now get all my vehicles serviced there. Thanks for the info!

sent you a pm...Feel better...oh...they have a 2023 z-51 convertable in the showroom . Its white... It only has like 145 miles....someone just traded it in...ck. it out while changing your oil

Yep FWIW the European 0W-40 Mobil 1 has been available for years. Same price in 5-quart jugs as the Mobil 1 meeting the required GM dexos spec I bought from Walmart for my 2014 Z51 and 2017 Grand Sport.
Just checked and yep still the same price: $5.49/QUART! Wouldn't that be nice. BTW it meets API (American Petroleum Institute,) Porsche A40 and other specs BUT not the GM required dexos spec, or ANY dexos spec.
Heck why would European Car Manufacturers want GM to get a royalty on oil they specify!
PS: Like many other oil company claims, it may reach 10,000 miles before it's worn out IF YOU DON"T EVER SHUT THE ENGINE OFF, HAVE COLD STARTS, etc! You're changing the engine oil at max 12 months for the contamination from cold starts, stop and go acceleration, additive depletion etc. Just like it said for all 6 of my Vettes starting with my 1988 1st.
I noticed that the 2020-2022 Owners Manuals list the required oil as dexos2 approved, 0-40. The 2023 Owners Manual lists dexosR approved, 0-40. The manuals mention the www.gmdexos.com website. Looking there, it appear that the dexosR is the so called Supercar formula, and only one oil is licensed to meet that specification. On that same site, under dexos2, there are 4 oils licensed to meet that specification, one of them is Castrol, the others are Mobil 1 formulations.
DEXOS 2
DEXOS R
FROM THE 2023 MANUAL, PAGE 247 WHICH IS THE SECTION FOR THE LT2 ENGINE. THE Z06 SECTION ALSO RECOMMENDS DEXOS R IN A DIFFERENT VISCOSITY

Small point BUT "dexos" is a GM registered trademark for their spec test, that they charge oil companies to use! It's a small "d."
Being the one who managed our many trademarks and wrote to folks using Heliarc etc saying STOP, just thought I'd mention! BTW API and SAE also charge for oil companies to use their oil specs and for putting meets API XYZ etc on their containers.
I conjecture, BUT probably true, in ~2000 when Mobil sued Castrol for using the word "Synthetic" (for just a more highly refined, what folks call "dino oil" and lost (forcing them and others making truly synthetic oil to switch to the half cost to produced more highly refined "dino" oil) BOTH SAE and API supported Castrol. Because they wanted oil companies to use (and pay for) their specs! That occurred ~2000 before GM decided to create their OWN spec and charge oil companies as well! BET API and SAE never saw that coming!
