The dealer said GM won't pay for it. Does this sound right to you?
If you buy it new from a dealership you get the first 2 or 4 free. My first one was free from a dealership, but was not the dealership I bought it from.
My local dealer in AZ (bought mine from Kerbeck) charged me $30 extra for Mobil1, but I've heard some people say they switched to Mobil1 for no up charge. I guess it's up to the dealer to decide what they charge. But one thing is for sure, you should get the first 4 oil changes for free during the first 24 months if you stay with the brand used at the factory.
Correct, factory fill is not Mobil 1 and GM only covers the factory fill (Dexos) under the 2 year free maintenance. We charge customers the cost difference between Dexos and Mobil 1 should they choose a Mobil 1 oil change (usually around $20).

Doesn’t matter who you buy it from, GM service practices apply. GM calls for DEXOS synthetic blend. The dealer has no requirement to put in full synthetic. They can if they want to be nice but they don’t have to.
Dealer makes the call on when and what goes into the car and any additional charges. Don
Bought my 2 jugs of Mobil 1 at Walmart for $21.88 ea and did it myself. I know what's in there and know it was done right. BTW, 10.3 or 9.8 is WAY too much oil in a Z51.
Yes it is! I've found ~9 qts to be correct for an oil change.
You're right. By the time I finished sucking out enough oil to bring the level to mid-range on the dipstick I had a 9-quart refill. Will be much easier on the next change!
My local dealer put in Mobil 1 at no extra charge. I thought that was really nice, considering I didn't buy the car from them (they had no allocations.)

Ah, not so fast. In the manual, page 10-14 to 10-15 (MY2014)
Specification
Use and ask for licensed engine oils with the dexos1® approved certification mark. Engine oils meeting the requirements for the vehicle should have the dexos1 approved certification mark. This certification mark indicates that the oil has been approved to the dexos1 specification.
Corvette recommends Mobil 1® engine oils that meet the requirements of the dexos1 specification for its dry sump equipped engines
There is also an insert I received with the car referencing Mobil 1 as the preferred fill as well as the Mobil 1 site quoting that the Z51 C7 is factory filled with Mobil 1.
NO NO NO, 9.7 qts is the new correct dry fill on a Z51.
I was told 10.2 quarts at the museum on the Z51 with a dry sump when I had a museum delivery and Mobil 1 is the preferred oil to use. I also was told by my dealer (not the one I bought from) I could have 4 oil changes anytime during the first two years.

this is what Palmetto Chevy in Conway SC told me, just pay the difference between dexos and mobil1.
The 2015 manual page reflects the same numbers as the corrected 2014 manual....
10.2 quarts is asking for trouble. Most who take the time to look in their intakes have seen the oil burps firsthand from the overfill, me included.
Plenty of discussion on this if you search. I like many fill with 9-9.4 quarts and have the oil about 1/3 up the hash marks. No more oil burps... This liquid oil in the intake can be a very bad thing if ingested in any quantity in the engine.

Then they told you wrong. There was a TSB along with a new owners manual insert that changed it to 9.8 (I was off too) and it was actually 10.3 qt. in the original manual.
Go here and look on page 12-2 for the proper fluid levels.

This was incorrect early information on fill quantity. Did you read the manual and/or update insert that was in the 2014 deliveries?
