SAN FRANCISCO -- The average price of regular gas in California has inched up to $4.671 a gallon, making it the highest in the nation for another day.
AAA reported the price was higher than Monday's price of $4.668, which also was an all-time high for the state.
Officials say they 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.
California usually converts to the gas on Oct. 31. The fuel evaporates in heat more quickly than summer-blends.
A fuel's evaporation rate indicates how much raw fuel enters the environment, especially in warm weather.
