Gasoline Prices Hit All-Time High Gasoline prices in California rose to another all-time high on Sunday after passing a four-year high a day earlier, according to AAA. The four-cent-per-gallon jump Sunday was even bigger than Saturday's jump, which was just a fraction of a penny. AAA reported in its latest update on Sunday that the statewide average price for a gallon of regular unleaded gasoline is $4.655. Saturday's average of $4.6140 was the highest since June 19, 2008, when it was $4.6096. Sunday's price, like Saturday's, was the highest in the nation, with the Golden State leapfrogging Hawaii this week as the state with the most expensive fuel due to a temporary reduction in supply. Californians are paying 24 cents per gallon more than motorists in Hawaii, according to the AAA report. In some locations, fuming motorists paid $5 or more per gallon while station owners had to shut down pumps in others. AAA's Daily Fuel Gauge report said the national average both Saturday and Sunday was about $3.81 a gallon, the highest ever for this time of year. The situation is compounded by a California pollution law that requires a special blend of cleaner-burning gasoline from April to October, said Denton Cinquegrana, executive editor of the Oil Price Information Service, which helps AAA compile its price survey. Among the recent disruptions, an Aug. 6 fire at a Chevron Corp. refinery in Richmond that left one of the region's largest refineries producing at a reduced capacity, and a Chevron pipeline that moves crude oil to Northern California also was shut down. There was some good news, however. Exxon Mobil Corp. said a refinery in Torrance returned to normal operations Friday after the power failure Monday disrupted production for most of the week. State officials said with the refinery coming back online, prices should start falling.
