As before I've run 0w-20, 0w-30 and 5w-30 with no refinement, economy or performance changes that I can percieve. I've just picked 5w-30 on price and the fact I use the car to commute, shop and lug the family around. I barely drive it above 3.5k, often not even 2.5k rpm.
Some will swear by 0w-20 or otherwise. Just use whatever you can afford or think is best. I think Honda themselves used to service with 0w-30 but have gone down to 0w-20. Although Coxs will sell you both grades, Honda's own is 0w-20.
