Oil

oil life is a product of time as well as mileage. if i remember manufacturer maintenance directive for c8's, its either of 7500 miles or 1 year but you really need to talk to your dealer if your purchase date is different than the book date from the dealer which is also different than its birth date from bowling green. Example, my 2025 car was born on oct. 11th, 2024, and arrived at the dealer on dec. 2, 2024 but listed the sale through GM as Jan. 2, 2025 but I didn't sign papers and write the cheque until march 26, 2025.
My dealer is letting me have my first oil change as soon as the roads are swept from rocks and sand, so a conversation with your dealer is important.
Personally from a break in point i highly recommend oil change after your second break in mark of 1500 miles at which point you are allowed to track the car as well as perform launches. I also highly recommend changing your DCT filter at this time. Some people recommend doing the oil change at the first break in point of 500 miles. Choice is yours really as its above and beyond what GM describes but when i cut open the dct filter and the oil filter i did find extremely tiny fines of break in material so i myself would highly recommend against continuing to recirculate that in the initial fluids from bowling green. Best to keep it as clean as possible and reset with new filters. You'll sleep better at night.
The DCT can be testy for some, but keep in mind the majority of forum posts you read on the DCT are only those who have problems and not the thousands that don't. I strongly believe you will prolong any potential valvebody issues by simply changing the DCT filter more often. Changing the internal filter at the prescribed GM interval is a whole 'nother discussion but i'm pretty sure its not required by GM techs at the 7500 mark or the next one...
my vin is 801, what's your 25?
