I was told by the service manager of the KIA dealership I bought my Stinger from that I would void my warranty of the car if he was to put in Mobil One Synthetic 5-30 into it on my first oil change at the dealership. He said they do not use that oil. He said I could bring the oil (over 6 quarts) into their service and they would use it but any engine damage or failure associated with the oil would void the KIA warranty.....I have never heard of this policy and wondered if anyone else has.
