Seriously though why are you departing so far from the honda recommended oil viscosities? If you look in your manual Honda only recommends 0W or 5W oils for very low start temperatures. Just get 10-30 Red Line. Track tested in 2 different states at a variety of temperatures on a ghetto old high km DC5.
