I have had my car for three months and thought Ow-16 was the oil it took, but have recently discovered southern and northern U.S. may use two different oils, Ow-16 and Ow-8. I live in northeast Indiana and kind of plan on doing my own oil changes and so, should I use 16 or 8? The owners manual specifies Ow-16, but I think this was originally sold in a southern state.
