Re: Best Oil for Z06 (Alternatives to GM4719 Spec Mobile1)
Realize I'm late to this party, but just bought a Z06 yesterday, and this is the first priority. I just got rid of my Accord with 185k, and my wife's with 150k, ran Mobil1 and feel there was a lot of life left in both cars, just got spooked--never kept a car that long. Also, talked to a NASCAR tech school graduate who had a Z06 for sale and he said no matter what oil sticker was on the car, every single NASCAR ran Mobil1. That said, he used royal purple, thought Mobil1 tended to cause leaks, but was a great oil. Just some input--sticking with Mobil1. Thanks for the great info!
