Price Relief Seen in CA Release of Winter-Blend Gas

So ... Why not use it all the time?

State air pollution regulators said Monday that California's air quality is not expected to worsen appreciably after the governor ordered the release of a dirtier blend of gasoline to help slash record-high pump prices.

The California Air Resources Board issued a regulatory advisory a day earlier after Gov. Jerry Brown ordered them to allow so-called "winter-blend" gasoline to be sold in California earlier than usual to increase supply.
