PRICEY FILL 'ER UP: The average price of regular gas in California inched up to $4.671 a gallon, making it the highest in the nation for another day.
WINTER COMING: Officials expect prices to fall after the governor ordered the release of a dirtier blend of gasoline to help slash record-high pump prices. But they say it could take a few days depending on how quickly refineries can get the so-called "winter-blend" fuel to market.
EARLY CHILL: California usually converts to winter-blend gas on Oct. 31. It tends to evaporate in warm weather faster than summer-blends, releasing more pollutants.
