Howdy, Just wondering on the gas situation? I realize that the car takes premium fuel only. Now thats all i have been puttin in it since 53,000 miles. And the original owner put premium in it until he sold it to the guy i just bought it from at 20,000 miles. so from 20 - 50k miles on the car it was only being given mid grade gas. Is there any harm that could have done the car? thanks.
