I will be picking up my 2010 Corvette Coupe this weekend. I am undecided which oil to use in this beast! I recall reading that the oil must meet GM's spec GM4718M. The dealer has told me that Mobil 1 is the factory fill and should be used. I am a PP fan and was hoping that I would be able to use it without voiding the warranty. There is way too much information on the web and I was hoping to make sense of it all on BITOG. I plan on keeping track of all oil changes for warranty sake. TIA for some insight!
