I bought a new kia forte, the dealership offers the first oil change for free. I emailed the service department and asked what brand and wieght oil they use. The service manager replied back with Mobil 1 Synthetic Blend 5w 30. I have never heard of or seen a Mobil 1 blend, can anyone shed some light on what he might be talkin about. Or maybe this guy is just a suit behind a phone and a desk and doesn't know what he is talkin about.
