Check out this video by YouTuber HorsePower Obsessed where he gets his first oil change done on his C8 Corvette which is free after 8200 miles *usually due at 7,500 miles. He mentioned the transmission filter should be replaced too but he thought that is suppose to be free or a credit for $205.00 to replace that.
He also shows C8 Corvette owners why they should have an oil catch can.
