We are neighbors,(im in Indiana. My wifes 07 accord v6 gets 5w-20 constantly, with (OUR) climate and the tempts we see, i dont see any necessary reason to go to the 0-20, although i do run SYN in the winter, and Dino in the summer, try it if you like.. let us all know if you notice a difference..
Now if we lived in a climate that seen negative numbers often in the winter i might think of trying it, but we dont.. so i dont see the point myself.
