Mobil 1 is dexos approved and is what I run in my V. Any dexos approved oil will satisfy warranty.

Not all dealerships are alike. My local dealership changes my oil in my 2011 V Coupe with whatever GM covers, which is the AC Delco Dexos 1 Synthetic Blend motor oil. If I want Mobil 1, I have to pay for it. Since I am leasing the car, I just have the dealer do it with what GM covers. If I bought the car and planned on keeping it forever, I would run Mobil 1 or better oil like Amsoil. No way I would let them put the cheap shit in my car if I was keeping it. The oil cap under the hood of my V Coupe says Mobil 1, but the dealer won't put Mobil 1 in it. Service manager told me that the factory used up whatever Mobil 1 oil caps they had left over, but GM won't pay for Mobil 1. Newer cars don't say anything on the oil cap. If your dealership is putting in Mobil 1 and charging GM for it, keep going there!
