True, but with racing, and me doing the short changes, it isn't worth it probably. I had three races on my last oil change with Amsoil 0-30 and it game out pitch black (never seen Amsoil come out that dark when I have changed it). I know you can't say by color, but that was pretty bad. With 4500 miles on it, that was pushing it. I think PP every 4-6k would be enough depending how much I drive.
Still trying to decide between 5w30 and 10w30. hehe.
