SAN FRANCISCO (October 4, 2012)--The cost of gasoline in California jumped 8 cents overnight and is set to soar to the highest point this year in what analysts say is a supply problem fueled by refinery and pipeline outages, according to the AAA's Daily Fuel Gauge released Thursday.
The report showed the average price for a gallon of regular gas rose 8 cents overnight, to $4.32, and was up 18 cents over the past week.
Average prices are also high nationally at $3.78 a gallon, but inventories in California are lower than they have been in more than 10 years.
The state's supply is hampered by its strict pollution limits, which require a special gasoline blend.
Patrick DeHaan, senior petroleum analyst at GasBuddy.com, said prices should continue to rise because wholesale gasoline prices have increased $1 a gallon, but average retail prices are only up 30 cents.
