My new Civic recommends 0w 20, however it is a bit more expensive, especially if done at a dealership. Is there much difference between 0w 20 and 5w 20? I heard the only reason Honda uses 0w 20 is to meet the MPG guidelines.
The reason the 0W20 is more expensive is that the base stocks it's made out of are of a substantially higher quality. Use the 0W20 and do NOT pay attention to anyone telling you to use the 3 month, 3,000 mile oil change interval- it's bunk on any car built after 1996.
