Any dino recommendations for the new Kia Turbos? Its a 280hp DI 4 banger so I have a feeling its gonna be rough on oil. I say Dino because the manual, as well as the onboard computer say 3k oci. 5w20 is recommended for "optimal fuel economy", but the manual states I can run up to a 40 weight. I'm thinking a 5w30 would suffice in a quaker state green bottle flavor. Any thoughts?
