1/3 of a gallon bottle.
At 1700 Miles I had a track day, the next day the top res was down about 2 inches from totally full, the lower was down about 1-1 1/2 inch. I topped them both off. Did another track day, only the lower res was missing about 1 inch. 3rd track day same thing, lower res down about 1 inch. Then about a week later (maybe 100 miles of driving) the lower res was down about 1 inch.
This is my 3rd gen 6 camaro, the first 2 being SS 1LE's (2020/2022). Neither of them took this much coolant. The 2020, needed lower res topped off after about 20k miles. Both were tracked without coolant loss in the same area/environments.
Day 2 haven't heard back from the dealer.
