I would stick with 5W30 and here's why. A multi-viscosity oil has a base weight of the lower number. Various polymers/additives are then added to the oil to prevent the oil from thinning beyond the upper number in the range. Ideally if we weren't racing a 30W oil would probably be ideal. However to allow us to drive around in the cold you want the lower base weight. Think about it as a polymer that's coiled and as it heats up it elongates. The 5W30 doesn't have to control the elongation as much as a 0W30 would? (Does this make sense?)
Please see this great link for info that better explains it than I.
In any case, I know that many 0W30 oils are starting to appear but until the manufacturers actually test and advise for them I'll pass.
