Why not just tell us the nearest big city and state?
Stay far away from any 5w20 with your Hyunkia four cylinder. Even in the colder Michigan winter, I run a blend of 10w30 and 0w40 in my 2.4 GDI.
Our Kia uses Amsoil Euro 0w30. It's thick.... right around 12.3 cst@100.
Thicker is better for these engines. Look what member Accent Abuser is doing with his.... and he runs 10w40 or 5w50 in cold Boston winters. Last I read, he was entering around 210,000 on his odometer and the engine hasn't been replaced.
