You could use the 5w30 all the time and your car will probably be better for it. the 1st number (5) represents how well is flows when cold at start up. The next number is how thick it will remain at operating temperatures when your car is warmed up and going.
Most of the world dosent use 0or 5w20. It's something imposed on the consumer here and in Japan etc. to try and drive down fuel usage a little bit at the expenses of proper lubrication. Ya know whenever you have the government involved in anything you can bank on it being useless and counterproductive.
Um, 5W-30 was also the result of "government interference", much like clean food and non-leaded paint and fuels...
